Yellow Jacket Gas Analyzer Kits

Overview

The YELLOW JACKET 40852 Mini Refrigeration System Analyzer, also known as the Mini RSA, is a compact digital add-on tool designed to work with existing analog brass manifolds. It monitors one pressure input and one live temperature, then automatically calculates superheat and subcooling values for nearly 100 refrigerants. Accuracy is rated at plus or minus 1.8 degrees F. The Mini RSA brings digital diagnostic capability to a traditional analog manifold setup without requiring a full manifold replacement. HVAC/R technicians use it to speed up system charging and diagnosis on residential and light commercial refrigeration and air conditioning equipment. The Mini RSA is suited for service calls where a technician already works with an analog brass manifold and wants digital readouts for superheat and subcool without investing in a full digital manifold system. It covers nearly 100 refrigerants, making it versatile across a wide range of modern and legacy refrigerant types. The unit operates in ambient temperatures from -4 degrees F to 122 degrees F, supporting year-round fieldwork in varied conditions. Key Features Automatic superheat and subcooling calculations for nearly 100 refrigerants Monitors one pressure and one live temperature simultaneously Accuracy rated at plus or minus 1.8 degrees F Designed to connect to existing analog brass manifolds — no full manifold replacement needed Battery life of 25 hours continuous use on a single 9V battery Operating temperature range…
