Sussex-based Servomex has launched a sensor that measures ammonia in industrial processes. Built around a tuneable laser diode, ‘Laser 3 Plus Environmental’ is a two-part device that beams and receives a laser that passes though process gas – across the exhaust vent, for example. It is used as the sensor in industrial processes – specifically the ...
