Valtest 371 A/C Diagnostic Tool

The Supercool Valtest 371 A/C Diagnostic Tool is designed to diagnose failing A/C systems with electronically controlled compressors. The Valtest 371 performs a quick, easy-to-understand analysis of the compressors operation, the strength of the electronic control unit signal, and the functionality of the valve by determining whether there is a short-circuit or open-circuit and whether the failure is in the electronic control unit or the compressor. The Valtest 371 makes it possible to effectively diagnose the new generation of electronically controlled A/C compressors.
