Description
Overview
GAOTek industrial fixed online hf gas leak detector has an LED display transforms the gas density in the operating site into standard electric current signal(4-20mA). This device has excellent performance, stable operation, and easy maintenance. Since detector also can detect various gas, it meets various requirements in the operation site; it has been widely used in petrol, chemistry, metallurgy, artifice, gas transportation, biological medicine and water procession etc.
