Testo 550 Data sheet

Refrigeration System Analyzer

The testo 550 is a high-performance Refrigeration System Analyzer that accurately performs temperature and pressure measurements in seconds. It automatically calculates

superheat and subcooling for 31 different refrigerants

quickly, and easily. The 550 is simple enough to use right out of the box and rugged enough for daily use by today’s demanding HVAC technicians.

Use it to service, maintain and commission all types of air conditioning, refrigeration and heat pump systems including the newest 16 SEER systems. Perform timed pressure drop tests as well as standing pressure tests required for properly commissioning AC/R systems. The testo 550 comes standard with a clamp probe, integrated hanger-hook and built in hose holders all packed in a rugged protective housing.
