CPS VG200 Digital Vacrometer Vacuum Gauge, Measures Microns, Millibar, TORR, Inches/HG, Two Button Operation, Automatic Temperature Compensation, 5-digit LCD Display, Padded Case, T-Fitting and Hook

I needed a micron gauge for a DIY heatpump install. Usually I go super cheap on tools I'll really only need once but I wanted to be sure that the reading was accurate as a leak is pretty expensive problem with today's refrigerants. This is a nice high quality gauge from an established company with a calibration certificate. I've seen a fair number of these being used in videos from HVAC professionals. I found the gauge to function flawlessly. This was a great value for a gauge that is certified to be accurate. Unit is easy to use, and includes the needed 9v battery. One of the best features is that per the manual, this gauge can withstand the pressure of the refrigerant when releasing the system charge so you don't need to remove the gauge from your core tool prior to releasing the refrigerant. It also includes a small padded pouch for storage which was a nice touch.

This worked perfectly to get my new AC unit set up and operating. Does not include battery so make sure you have a 9v handy.

This is a great vacuum gauge. It is very accurate and works perfectly. I’ve used it in two air conditioners already and used it on the same air conditioner multiple times. I highly recommend this brand for how easy it is to place on the low side valve. They even give you a t fitting to tee off the hose. Because of the price, I try to treat it well but I can see how durable it is. Everything can be hand tightened and it doesn’t leak.

This unit works as advertised.

Gauge seems to be accurate, included tee is JUNK! Gauge went to 3 microns…. Gauge with the included tee won’t go below 500 on a 9cfm pump. Tried a different seal in it with zero change. The solder / braze job on it is leaking. Not happy about that!

This is a high quality, well made product. The sample speed is fast enough, but there is a delay between the actual pressure and the displayed pressure. It has multiple different units that it can display the value in. I bought it because I needed a micron display. Included accessories are a hanging bracket, a pouch for storage and a "T" adapter. To power it up, you need to install a nine volt battery.

The price is right on this vaccuum guage for the buyer, and the quality is high. It does have a plastic case so you still have to try to NOT drop it from very high...... might or might not break obviously. Even so, it is an excellent and simple device that will take merely a few minutes to install the new battery and have it ready to perform for you. I like the compact size, the very high quality of the MADE in USA parts and pieces, and the nice little protective carry case that comes with it. Compact, high quality, handy and easy to use, low priced..... how can you go wrong? It all fits in this small soft case that is about 6" long by 3" wide, by about 1.75" deep, that is so compact and well protected that it should provide long time good service. Do enjoy! UPDATE 29 May 2014: I finally received my new vacuum pump and put this to work. It takes a little bit for it to settle down at first, but after that, this is a fine instrument I could recommend to anyone. I like the compactness of it, and the quality in the brass fittings is excellent! (USA made, so no surprise there,eh?) It is easy to read, just large enough to be great. The ability to select any type of readout you desire, from Torr to Microns, is good too. It did not repsond well to upper vacuum levels of say 10" and less, but once pumped down below that, all worked very well and was stable. Enjoy!

I purchased a discounted CPS micron gauge from JBTools, who described the gauge as being in "very good condition". The gauge is advertised to include a 9V battery, which was missing from the package. I purchased and installed a new 9V battery. Without pressing the gauge power button, the gauge instantly displayed a 1-micron vacuum (see pictures) without being connected to anything. I repeated the process several times and obtained the same result. I quickly returned the item and also sent a message to JBTools, who has not yet responded. If you look at the reviews for this gauge sold by JBTools, there are MANY Amazon customers who have had the same or similar experience with both new and used CPS micron gauges, suggesting that JBTools KNOWINGLY sells defective CPS gauges. How long will Amazon allow this to happen?

Arrived quickly and is exactly what I ordered.

Works fine on test easy to use Fast delivery

The gauge worked extremely well. The gauge arrived in good condition and was never opened damaged or broken. Remember to use nylog on all connections including the testing valve seats this will help prevent leaks
