Non-intrusive calibration

Calibration can be performed locally without the need for hot work permits – minimises operational down-time
Local display and buttons enable calibration without opening the junction box

Flexible output options

4-20mA current sink – works with a wide selection of control panels
2 wire format

Rugged and reliable

Made from tough carbon loaded nylon
Ingress protection to IP65 as standard

Low cost of ownership

Non-intrusive one man calibration – easy to operate and maintain
Long life sensors – keeps interuption to on-site activity to a minimum

Simple parts replacement

Wide range of sensors
Extensive range of electrochemical sensors for toxic gases and oxygen
