E-Sense is our new signature range of electrochemical gas detector. This versatile unit boasts several great features including: 2 or 3 wire operation, ability in the the 3 wire mode to be able to connect to either 4-20mA or 0-20mA controllers, it also boasts the ability to change the sensor detection range by half, other features are a test pot (gives the ability to test system wiring and alarms). Fine, course and span adjustment pots for a more accurate calibration, dedicated mA test points (for a single person calibration at the device). New brass design to allow’s you to have options when it comes to servicing, you can either replace the whole brass head or you can just replace the sensor element held within the brass. Replacing the sensor element will reduce your servicing costs, all while using this new design has helped us to create a more reliable sensor with a better IP (Ingress Protection) rating with the non-reactive gases that now include a titanium sinting that will give you an IP53 rating.
