  • Great gauges
Model: LM 120
Great value for the money, easy to read and built well. Easy to use and accurate

  • Will need analog gauges
Model: LM 120
It's decent but you will need analog gauges to verify pressures. You can recalibrate and zero out the pressure but you could have pressure in your lines still. Temperature sensors are good but would work better if the clamps had a copper insert for the sensor that covered the surface area of the hoses toy clamp to. I'm gonna make some new clamps with my 3d printer and add space for thermal conducting material in the clamp so the sensor gets a more accurate reading. But still it's decent for the cost. Just have to know what you are doing and verify your pressures when you use this ... show more

  • Disappointed over all
Model: LM 120
So far I liked it up till I used it, got to a job as an Hvac tech hoses do not work. Don’t know weather they are for a different refrigerant but they did not work. I was under the impression it includes “clamps” for sub cool and super heat, fine that may be my fault, it advertises Bluetooth has no Bluetooth feature. No plug in for the clamps either pretty disappointing. Note: if you are a using them for regular gauges with out clamps (No super heat or sub cool) just for charging, pressure testing, vacuum then these are for you. Tip: if you service 410-a, 407c/r22 KEEP IN MIND THESE HOSES WILL NOT WORK THEY DONT READ AT ALL. Make sure you order separate hoses ... show more

  • Good design easy to use for charging
Model: LM 120
I use this for charging and checking super heat and subcool. My testo meter temp sensors failed just cause of the location it’s on the sides. I ended up buying these and it’s sensor connections are on top so less likely to get messed up. Use it now for every call for a couple months no issues yet.

  • Not a micron gauge
Model: LM 120
This product is alright. It will not work for us hvac systems technicians looking for microns. You’ll need the Lm130 not the Lm120. Gotta return it. :-(

  • SH/SC function did not work, AUTOOL non-responsive
Model: LM 120
If you know refrigeration the unit functions fine. The onboard P/T tables match my printed material. The temp clamps are a bit cheezy, but hey, it's a $125 unit, not a JB or Yellow Jacket. The unit photos show a SH/SC function, and the chenglish manual mentions it, but I found no way to enable it. Yes, I can take saturation temp and the measured temp and calculate the SC (TXV systems) or SH (piston systems) but if the unit can do it, why not use that feature? I contacted AUTOOL, the 1st time they said I needed to purchase temp clamps (included so why purchase?) and when I plugged them in, the unit would automatically switch from Ev/Co to SH/SC. I replied I already have the clamps and the unit does NOT do so. No response. Follow up email 48 hrs later....no response. My 2nd inquiry where I was clear I have said temp clamps has also gone unanswered, hence the 2 star rating. If any fellow owners have made the SH/SC function to work, I'd love to know how, otherwise I'll just use it the same way we've used analogs for years. ... show more

Works as described!! Good battery life. Temperature clamps are junk though. Didn't use the hoses as I have better ones than it comes with.
