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.
1. Please operate according to the requirements of operating instructions or theguidance of professional personnel.
2. The digital gauge should be keept clean, the display screen should be bright andclear, so that the data on the display screen clearly.Use slightly alkaline detergentor soapy water to wash the case and connector.
3. The pressure gauge is perishable goods,need to checking regularly to ensure itsaccuracy. 4. Handled gently , to prevent shock and fall.
5. After use, please close all the button, to improve the service life .
6. Plug the joint when not use,to prevent foreign body from entering, clean andreplace regularly refrigerant tube, remove dirt and impurities in valve.Online Support>>
Working Principle: The Digital Manifold Gauge Set for HVAC accurately measures refrigerant and vacuum pressures (±0.5%), making it ideal for installation and servicing.
Double Display Interface:This AC Refrigeration Tester shows both high and low pressures and temperatures. The blue arrow indicates low pressure, and the red arrow indicates high pressure.
Three Working Modes: The system features three modes: refrigerant pressure, vacuum percentage, and leak detection. Select the mode that fits your needs.
Built-in 90 Refrigerants:The MRCARTOOL hvac gauges includes data for 90 refrigerants, following US NIST standards.
After Sales Service: Enjoy a 2-year warranty and 24/7 customer support. No need for extra warranty coverage. Contact us with any questions or issues.

Jeremy Sainsbury (store manager)–
This is a very nice manifold set. I love the backlight. I can finally see pressures when I’m back behind some equipment. I also like that I can see vacuum pressure on high and low sides — my old manifold set would only let me see vacuum on one side.
This set takes two 9 Volt batteries. It includes 5/16″ SAE adapters that you need for R410A ductless mini split systems. It doesn’t include any car adapters but those are easy to come by.
The valves are 90 degree turn butterflies and are quick and smooth.
Everything on this manifold set works rather well. It is a tiny bit cumbersome to cycle through all the refrigerants but if you know your pressures you can just skip that so it’s barely an inconvenience.

As someone who values precision and efficiency, I was skeptical whether a digital manifold gauge would truly meet my expectations. However, the L302 set pleasantly surprised me – it combines technology and user-friendliness in a way that is ideal even for ambitious DIY

The high-pressure gauge reads -0.80, and the low-pressure gauge reads zero. The specification specifies an accuracy of ±0.50, but the actual reading deviation is 0.30. Other functions, such as the temperature and pressure of various refrigerants, are easy to use. Hopefully, this pressure gauge will continue to function normally until it completely breaks down.

This MRCARTOOL HVAC manifold pressure gauge kit is fantastic! It accurately measures refrigerant pressure and vacuum pressure (with an error of ±0.5%), making it ideal for installation and maintenance. It supports 90 NIST-compliant refrigerants, features dual displays clearly showing high/low pressure with red/blue arrows, and offers three modes (pressure, vacuum, and leak detection) that perfectly meet my needs.

Easy to inspect, convenient to use, capable of testing most refrigerants on the market. With this tool, you can even check your home air conditioner. One meter, multiple uses—truly excellent.
