Specially designed for pressure measurement in refrigeration systems operated with ammonia-free refrigerants ((H)CFC / HFC)
Twin scale in bar and °C. The line pressure in bar corresponds to a converted refrigerant temperature in the cooling circuit. The temperature scale is coordinated with the respective refrigerant, e.g. R12, R22, R502, R124a.
Easy mounting in control or indication panels from the front with screws or rivets
Bayonet housing allows correcting adjustments after calibrations
Suitable for gaseous, low-viscosity and non-crystallising measuring media that do not corrode brass
