HVAC/R Gauges

Refrigeration Ammonia Gauges are designed for use on ammonia compressors and other ammonia refrigeration equipment. Ammonia Gauges include a restrictor that protects the gauge against sudden shock or pulsating pressure.

The inner dial arc shows pressure, (psi/kpa) outer arc shows the corresponding temperature scale. Refrigeration Ammonia Gauges are available in plain stainless steel case.
