Selling Fixed HCL Gas Monitor With LED screen

Description

QB***0N/T is Industrial grade LCD/LED gas leack detector, with ***0 mA or RS**5 ModBus RTU outputproportional to the gas leakage concentration with original imported electro-chemical sensor. The online gas detector transmiteer monitors gas leakage by natural diffusion. It is flexible, durable, accuracy, stable and etc. and it can be directly connected with DCS systems or Central unit. With relay output, once the concentration exceed the preset alarm point(threshold) it will start the acoustic-optical alarm on the central unit and drive the external equipment like exhaust fans.

It has been widely used in petrol, chemistry, metallurgy, artifice, gas transportation, biological medicine and water procession etc.
