It isn't warming up for 3 minutes. It doesn't read anything until you only have 1 in of mercury of atmospheric pressure left. It doesn't read until you have 25,400 microns because the gauge is used in the HVAC field, and we don't care about anything above that. Shuts down at after 5 minutes to save battery life, because we never use it INSIDE a vacuum, we use it to read a vacuum in our refrigeration systems.

It will not start reading until it gets to about 25,400 microns, which is about 1 in. of mercury of atmospheric pressure left. This gauge is used a lot the HVAC-R field for us to pull down a 500 micron to dehydrate our systems. To my knowledge, there is no way to remove the 5 minute shutdown. We use these vacuum gauges to read the system directly via a schrader core, or our manifold gauges, and obviously the shutdown feature is there to save battery life, because we can simply turn it right back on. Used this specific vacuum gauge for awhile, and various other ones for 25 years now.

I'm a refrigeration tech, and I use gauges and pumps exactly like this on a daily basis. CPS is in the low end of tools, but I suspect nothing is wrong with it. It's accuracy is measurable under 1000 microns. The auto off is almost mandatory because the heater element will chew through AA batteries in no time. I use Yellow Jacket, and it takes larger D Cell batteries, has no auto-off, and can operate about 6 hours on one battery. Assuming Cody is using standard 1/4 refrigeration hoses for his pump, he just needs a 1/4 flared MMF tee and hook up the gauge outside the chamber. Otherwise, he might have to get creative and weld in a fitting. Other tips for pulling vacuums. Any liquid moisture will almost certainly degrade your pump oil. Change it every time, or at least every time you pull a very high moisture load. If the oil is not clear, change it. Also, don't be shy to run the pump for 24Hrs. On one extreme job where I had a vandalised 50 ton AC unit exposed to the Canadian winter for months, I had to run 2 pumps in tandem for a week.

Hey, I hope you see this, Cody! I bought a high vacuum system with a roughing pump, turbomolecular pump, all of the gagues AND the instruments to read them (thermocouple gague and parani gague, automated valves...the works! Only problem is I live in Taiwan (and I already have other components for a system, just not all put together yet) and I think shipping it here would take forever. I don't know if I will stay here forever, so if you want, in the meantime (probably at least a year?) you can totally use it for all sorts of awesome stuff! It is in Denver right now, so if we can find a way to get it to you its cool if you use it for anything!

This is for use on a refrigeration manifold with 3/8 ports and reacts faster as it's connected via a small port directly on the manifold and can easily be switched on and off to check if vacuum is holding at a specific micron range there are analog versions of these that read in torr you still will need to connect it to a gauge manifold however it will not turn off every five mins 👍🏻
@rcflyer182

Use this particular micron gauge for work. One option for you Cody would be to get a cheap manifold gauge set. You could put the micron gauge on the manifold gauges and then you could also isolate the vac pump if you wanted to hold the pressure. The manifold gauges also go into negative pressure.

I work with micron gauges everyday in the line of work I do. In HVAC when we vacuum your copper line set we have to pull to a minimum of 500 microns by law. if your having issues pulling a deeper vacuum change out your vacuum pump oil IT IS hydroscopic. Also take your new vacuum pump oil and grease any threads on your hoses and connectors to reduce leaking.
@AWIERD1
7 жыл бұрын
Also I assure you I'm 99℅ positive it's not a defective micron gauge. Are the hoses you are using vacuum rated or a good HVAC quality brand like Yellow Jacket? Do you only have a 1/4 threaded fitting off your vacuum pump? Use 1/2 hose or 5/8 if it's available it makes a huge difference. Also like other people suggested a smaller hose is more efficient as well. I have a 2 stage 7cfm vacuum pump with vacuum rated equipment and I can pull a 50 micron vacuum in less than 5 minutes. This would be 20 feet of 7/8 and 1/4 copper and the evaporator.

I calibrate gauges and chart recorders for a living. May I recommend you look at gauges by Druck or by Keller. Accuracy of them can be as little as 0.05% fsd. Not cheap but some of them also have recorder functions allowing you to view your data afterwards. Failing that, I would look into the cheaper option of a vacuum transducer with a digital indicator threaded into the side of the vacuum chamber. Also, car turbo boost gauges can be bought fairly cheap and can be purchased pre calibrated. Sorry to go on. Great videos!

You could easly tap and thread a fitting into the front window. It probably isn't getting full effect because it's designed to have air from inside pulled out. using it the proper way would seat the inner valve better than what he is currently doing. the outside pressure would help it read more accurately with the outside pressure acting as an insulator. That being said it doesn't mean that it should read less In low atmospheric pressure, it would be the +/- 10% error in your readings. Again, I don't know much about the product it is just my theory.

I use micron gauges and vacuum pumps every day for refrigeration work and you should know that pulling a perfect vacuum is not an easy thing to do, a critical component of getting a good vacuum is to change the oil after every use and ensure any leaks are completely sealed, not only that it takes time to evaporate all the moisture from the air.

Cody, have you ever thought of increasing the number of pumps you have? In my opinion, what you have now, is a good middle vacuum pump. I would suggest you look at a simple centrifugal roughing pump (essentially you could steal one out of a seal-a-meal vacuum bag machine, or go a bit larger). This would be to save wear and tear on the oil vacuum pump. Once your roughing pump and vacuum pump have finished, you could go further with an ion pump (or ion sputtering pump). I would imagine you could build one, or you could find a surplus electron microscope to snag one from.

It would be easy enough to rig a system with an Arduino and a transistor to activate the meter remotely. The Arduino would just look at a photocell or a photoresistor, and when it is activated with a bright light or a laser it could turn on the transistor for a short time, which would emulate pressing the switch. The code for that would be a piece of cake to write.

This gauge is used in refrigeration and air conditioning. After a repair is made to a unit, by Australian law technicians must vacuum the unit to 130 microns before charging the AC or fridge with gas. These gauges are top of the line and work beautifully when combined with a proper vacuum pump and a correct set of refrigerant gauges.

If you do keep it you most likely can sodder a wire to pcb of the device on top of the current power switch, and then run the wire outside the vacuum chamber then a button on the other end. I would use ribbon cable from something like an old cd rom head (you could also harvest a button too), its flexible and runs flat. With a bit of silicone you could make a seal that can have the door seal to it and keep a vacuum. This would definitely void any warranty / return policy.

No, but that's just over complicating things. He'd just need to drill and tap a hole in the chamber big enough to secure a fitting in there for the gauge to go on. He could even weld it from inside to ensure it's airtight if he wanted to.

When you made the mercury vacuum gauge, did you fill the tube with mercury, then bend the glass? I really like that gauge and wish you had a video on making one.

hey cody, what would happen if u put a thermometer inside a vaccum and then shined a bright light on it. would the light still generate heat in a vacuum?

Cody you can solder on that meter photo light switch (light sencor), or how it is called in english so you can turn it on with laser, or maybe use the heating power of the laser ?

We also use digital meters to read out vacuum inside of our spectrometer measurement chambers. There the air is sucked out to not interfere with the X-ray's as the molecules of air would also be measured instead of only the measurement sample. For measuring liquid smples, we fill the chamber with helium, this is done just below outside pressure so we know the chamber is sealed for X-ray safety. For this we measure pressure on a different meter that is calibrated for reading close to atmospheric pressure. When the change of medium (vacuum to helium) happens in the chamber, the readout of both meters are always off. What I want to say is. It is "normal" that this gauge is not reading correctly on low vacuum. They are only accurate in high vac. It's due to the effective range of the meter. I even believe its not linear either. Our meters for reading 0,5 Pa to 20Pa, they only start to be accurate/reliable under 200Pa. For lower vac you need second meter. Hope my English was understandable as I greet you from Belgium.

I believe it was on too long before the vacuum s pulled. In a full atmosphere, the heater heated the thermometer too much, and it was waiting for it to cool back down before it got an accurate reading, which is why it dropped so fast once it started reading.

would it not be possible to just seal the end of a positive pressure gauge and use that as a vacuum gauge in the chamber? Maybe also add a small air tank to it?
