Why is Auto Digital Refrigerant Manifold Gauge needed?
Nowadays, the technology used in auto air conditioners is more and more advanced, but its basic refrigeration principle has not changed, that is, the compressed refrigerant absorbs a large amount of heat energy through rapid volume expansion at the moment of pressure release. This is the same as the working principle of indoor air conditioners, but because the working conditions of auto air conditioners are more complex and severe (bumps, high temperatures, and frequent switching) compared with indoor fixed air conditioners, refrigerant leakage is prone to occur. Repairs and maintenance are also more frequent.
Refrigerant Manifold Gauge also known as refrigerant pressure gauge or fluoride gauge. It is mainly suitable for air extraction and pressurization in refrigeration maintenance, for filling air-conditioning refrigerant, and displaying real-time pressure.
With the continuous innovation of refrigeration technology, with the new device of the auto digital refrigerant manifold gauge, users will be able to process all measurements on the auto air conditioner refrigeration system and heat pump faster, more reliably and more flexibly than ever before, helping users to better understand the auto air conditioner system operation, quickly debug or solve system failure problems.
With intelligent professional measurement technology and detailed display interface, the auto digital refrigerant manifold gauge has become a reliable partner for debugging, repairing and maintaining refrigeration, air conditioner systems and heat pumps.

Evaporating Pressure and Temperature Measurement
Measure the maximum pressure when the refrigerant changes from liquid to gas, and the minimum temperature when the liquid changes to gas (the lower the evaporating pressure, the lower the evaporating temperature, the higher the refrigeration cycle efficiency, and the greater the refrigeration capacity).
Condensing Pressure and Temperature Measurement
Measure the minimum pressure when the refrigerant changes from gas to liquid, and the maximum temperature when the gas changes to liquid (the lower the condensing pressure, the lower the condensing temperature, the higher the refrigeration cycle efficiency, and the greater the refrigeration capacity).
Intelligent Digital Display
The AUTOOL LM120+ Refrigerant Manifold Gauge adopts large-size LCD liquid crystal display, which is supported by LCD backlight, and the data display is clear and easy to read. Users can complete the operation through the buttons on the operation panel throughout the process. The display is rich in content, and the operation process and data are clear at a glance, which significantly improves the maintenance efficiency.
Pressure Maintaining and Leakage Test
The pressure difference between the initial test pressure and the secondary test pressure is calculated to determine whether the refrigerant is leaking.
High Pressure and Low Pressure Measurement
Measures the pressure of the refrigerant in the high and low pressure pipes in the air conditioning system.

Rubbish things, the tubes are not sealed at all, my refrigerant has leaked out, and I didn’t see the storage bag that came with it, it’s really rubbish

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.

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. :-(

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

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.
