Product Introduction

        The NDOP30 SF6 Gas Quantitative Leak Detector is a newly designed product by our company. Its principle is based on the fact that when the concentration of sulfur hexafluoride gas in the air changes, the degree of ionization of this mixed gas under a high-frequency electromagnetic field also varies. By detecting the degree of ionization, the concentration of sulfur hexafluoride can be determined.

      This instrument has been upgraded with an alarm setting function. When the detected gas concentration is greater than or equal to the set value, it automatically emits an alarm sound.
       This device is specifically designed for leak detection in SF6-filled equipment and containers in sectors such as power, railway, electrical appliance manufacturing, chemical industry, firefighting equipment, and atomic physics research. It enables rapid and accurate qualitative and quantitative detection.

Product Features

       The instrument uses a small vacuum pump, with the probe and main unit being separate. It features small size, light weight, portability, high sensitivity, stability, fast response time, probe resistance to poisoning, and no generation of toxic gases. It also includes an LCD display for gas concentration, making readings more convenient and accurate.
