Ammonia Gauges
These gauges are designed for the pressure measurement of any system or equipment charged with ammonia.
All dials are furnished with corresponding temperature scales. Black inner arc indicates pressure. Red outer
arc indicates corresponding temperature. All gauges are equipped with restrictors to protect the gauges against
pulsating pressure.

Diaphragm Gauges
The Weiss DG series gauges are used in the measurement of pressures
below 10 psi. This line of diaphragm gauges offers an instrument highly
sensitive yet durably constructed. Utilizing a thin walled copper-alloy, the
diaphragm senses slight pressure or vacuum and expands or contracts. The
action of the element is quickly and accurately indicated within 1.5% of full
scale range. Some of the uses are filter monitoring, leak testers and LP gas.
