The measurement device is mounted with brackets at the back in control and indication panels without any visible screws
Bayonet housing allows correcting adjustments after calibrations
High measurement accuracy: class 1.0; i.e. +/- 1% of the span
The pressure gauge has a twin scale indicating bar and °C. The line pressure in bar corresponds to a converted refrigerant temperature in the cooling circuit.
The corrosion resistant stainless steel measurement system and housing is specially designed for use in refrigeration systems with measuring media containing ammonia (NH3 measuring media).
