DUST-AD
IP65 Aluminium and Stainless Steel body
Ideal for detection of combustible gases and solvents
Strong poison resistant properties
Thanks to introduction of modbus or Bluetooth protocols it is possible to establish a direct communication between the sensor and your PC, PDA or Mobile Phone.
This features allow you a complete control of all sensor’s functional parameters such as Zero, Span, Sensitivity, Alarm Thresholds TWA, STEL and Download maintenance operations reports or events Log.
