US Gauge Model 1706 Ammonia Pressure Gauge

The Model 1706 gauge is usually installed in ammonia refrigeration systems. The 1706 compound gauge can also be used to handle other chemicals not injurious to wetted parts. The silicone dampened movement greatly extends gauge life, particularly on tough services like ammonia compressors. Temperature equivalent scale in red provides easy analysis of refrigeration systems.
