The Gas detector is designed for the detection of Ammonia NH3 and provides 2 internal relay outputs for ventilation control and alarm, a 85 dB Alarm buzzer and an LED alarm indicator.
The Gas detector provides analogue (4-20mA and 0-10VDC) and digital (Modbus RTU) output signals.
The supply of the gas detector is 24 VDC or 230 VAC and can also be operated „standalone“ without any gas monitor.
The light grey ABS plastic enclosure is IP 65 protected and the internal sensor can be easily replaced when its life
time is over.
Optionally the Gas detector is also available with an remote sensor, integrated display or in a neutral IP20 enclosure for Indoor-Installation.
