Yellow Jacket 40852 Mini Refrigeration System Analyzer

Product Description

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.

Compatibility

Designed for use with existing analog brass refrigerant manifolds. Supports nearly 100 refrigerants for broad compatibility across residential and light commercial refrigeration and air conditioning systems.

Installation Notes

Installation and use of this analyzer should be performed by a licensed HVAC/R technician familiar with refrigerant handling and EPA Section 608 regulations. Connect the Mini RSA to the manifold and temperature probe before attaching to the system service ports. Ensure the system is isolated from power before connecting or disconnecting service hoses. Follow all applicable safety guidelines when handling refrigerants under pressure.
