This detector is best suited for wet and corrosive industrial installations, Coastal and marine and food processing plants, it has alarm data capturing function that will save the alarm value with date and time. The clear LCD display will allow you to see the preset alarm values and the real time value been measured. The SIG-G1-XD-SS has a self diagnostic software to identify faults with the sensors and faults with the wire ways. The digital sensor output is linear to the sensor reading with fast response ranging from 2-5 seconds depending on sensor type being used.
