AUTOOL Auto Digital Refrigerant Manifold Gauge sells well in more than 160 countries and regions around the world, and are widely trusted and praised by users. 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. AUTOOL LM120+ is a new generation of multi-functional intelligent auto digital refrigerant manifold gauge introduced to the market. This product can be used as an auxiliary measuring instrument for the installation, testing, and maintenance of auto air conditioners and other refrigeration equipment. It is characterized by dual pressure test, dual temperature test (test clips required), digital display, digital display, multi-unit conversion, multi-mode function, and refrigerant parameter database. It is committed to becoming a professional measurement device for the maintenance and commissioning of air conditioning and refrigeration systems. Compatible with 89 Kinds of Refrigerant: R11 R113 R114 R115 R116 R12 R123 R124 R125 R1270 R13 R134A R14 R141B R142B R143A R152A R170 R21 R218 R22 R227EA R23 R236EA R245CA R245FA R290 R32 R401A R401B R401C R402A R402B R403A R403B R404A R405A R406A R407A R407B R407C R407D R407E R408A R409A R41 R410A R410B R411A R411B R412A R413A R414A R414B R415A R415B R416A R417A R418A R419A R420A R421A R421B R422A R422B R422C R422D R423A R424A R425A R426A R427A R428A R50 R500 R501 R502 R503 R504 R507A R508A R508B R509A R600 R600A R717 R744(Co2) R1234(R1234YF) 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). 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). 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. The pressure difference between the initial test pressure and the secondary test pressure is calculated to determine whether the refrigerant is leaking. Measures the pressure of the refrigerant in the high and low pressure pipes in the air conditioning system. 1* AUTOOL LM120+ Main Unit 3* Special connection hose (red, blue, yellow) 2* Test clips (with temperature sensor) 1* User Manual 1* Certificate Pressure test: Surface pressure Pressure test unit: Kpa; Mpa ; bar ; inHg ; PSI.

  • 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

  • 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.

  • 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

  • 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
