MRCARTOOL L302 Digital refrigerant gauge adopts the most advanced digital circuit and the high precision pressure sensor, used for both high accuracy refrigerant pressure and vacuum pressure,90 refrigerants build-in according to NIST standard refrigerants pressure and temperature relationship database, real-time test of pressure got relative temperature which can help you more convenient for refrigeration system installation or servicing.
- First, attach the hose securely to the low-pressure pipe to ensure a tight fit.
- Next, connect the vacuum machine to the right port and make sure it is sealed properly.
- Then, carefully unscrew the low-pressure valve to release any pressure, using the right tools to avoid damage.
- After that, turn on the vacuum pump and let it run until it reaches a complete vacuum.
- Once the vacuum is reached, connect the service hose to the refrigerant canister, making sure it is tight.
- Meanwhile, start the vehicle’s engine to power the air conditioning system during this process.
- In addition, set the air conditioner to the maximum level to ensure proper refrigerant circulation.
- Finally, check that the unit is in switchable mode for efficient operation and make adjustments as needed.

I gotta say, this MRCARTOOL L302 digital refrigerant gauge is a solid buy! Super easy to use, and the digital display is clear and accurate—no more guessing like with those old analog gauges. The build feels sturdy, and it works perfectly with R410A and other refrigerants. I’ve used it for a few HVAC jobs already, and it’s been spot on every time. If you’re looking for a reliable gauge without breaking the bank, this is the one!
I'm very happy with this digital manifold. It works great and it's extremely capable. You can use a ton of different refrigerants with it and it's very easy to select which refrigerant you're servicing.
Thank you
Top unit, ultra fast. Parabens mrcartool
