The Testo 0638 1742 Oil Pressure Probe enables reliable measurement of lubricating oil pressure in refrigeration compressors, helping technicians prevent failures caused by low pressure and insufficient lubrication. With its compact, user-friendly design and a long 2.9 m cable, the probe offers unrestricted access even in tight installation environments.
Resistant to refrigerants and oils, this probe is engineered for demanding HVAC/R applications. Its 7/16" UNF (¼ SAE) pressure connection ensures secure and leak-free attachment to compressor oil measurement fittings. When connected to a compatible Testo measuring instrument and set to the “Pressure/Compressor” menu, the lubricating oil pressure is displayed instantly—improving diagnostic accuracy and maintenance efficiency.
Ideal for refrigeration service professionals, the probe provides essential performance data for maintaining compressor reliability and protecting system components.
