Ammonia Pressure Gauge.

Ammonia Pressure Gauges are specially designed for applications involving ammonia and other compatible refrigerants. These gauges are constructed using materials that resist ammonia corrosion, ensuring safe and reliable pressure measurement in refrigeration and cooling systems.

They are widely used in industrial refrigeration plants where durability and accuracy are critical.
