Signalpoint Pro Detector
Use
Fixed point gas detector designed to detect toxic or Oxygen gas hazards that are
commonly found in industrial applications. When installed with a suitable barrier it is
suitable for safe area and European Zone 1 or 2 and North American Class I Division 1
areas.

Detection performance is temperature and humidity dependent. Listed data is based at 20°C, 50% RH only. Response time is
longer when operating in colder temperatures.
* Based on a 20-25°C temperature, 50 to 80% RH, using a calibration gas flow housing on a freshly calibrated instrument. If different
cylinders are used, other that the calibrating source, the cylinder tolerance will be taken into consideration.
