SF6 Gas Quantitative Leak Detector

Product Introduction

The MEJL-WK1 Portable SF6 Gas Leak Detector is a high-precision, high-sensitivity leak detection instrument developed by our company. It utilizes non-dispersive infrared (NDIR) technology to locate and quantify leaks. Compared to previous generations, it offers faster testing speeds, enhanced portability, replaceable batteries (enabling unlimited runtime), greater reliability, and superior cost-effectiveness.

Utilizing the Smart Quick Intelligent Power Testing System (Software Copyright Registration No. 1010215, Trademark Registration No. 14684781), our company incorporates internationally advanced detection technology in its R&D and production. It is primarily applied for leak detection in GIS and SF6-filled electrical equipment within the power industry. It enables both qualitative and quantitative testing of SF6 gas electrical equipment. The annual leakage rate of SF6 gas electrical equipment is measured using the wrapping method. Additionally, this device is widely used for SF6 gas leak detection across multiple fields, including power supply bureaus, substations, high-voltage switchgear companies, laboratory safety fume hoods, and scientific experiments.

FAQ

1)Why does the MEJL-WK1 SF6 Gas Quantitative Leak Detector not require regular sensor replacement?

Answer: This instrument employs Non-Dispersive Infrared (NDIR) technology paired with top-tier sensors imported directly from Germany. Its non-contact measurement capability prevents sensor poisoning. Additionally, the sensor is housed in a temperature-controlled chamber to prevent thermal drift, ensuring stable performance without wear-prone components. Consequently, regular sensor replacement is unnecessary, eliminating secondary investment costs.

2)Is the MEJL-WK1 SF6 Gas Quantitative Leak Detector convenient for use during elevated field operations?

Answer: Extremely convenient. Compact in size (245mm × 125mm × 140mm) and weighing only 1.5 kg, it can be handheld or worn on the body. Equipped with Russian military-grade Picatinny rail mounts, an air-cushioned massage anti-slip shoulder strap, non-slip handles, and a fall-prevention wrist strap, it allows operators to carry it effortlessly during elevated work while ensuring safe and comfortable operation.

3)How does the MEJL-WK1 SF6 Gas Quantitative Leak Detector prevent false alarms during testing?

Answer: Firstly, the instrument exhibits single-gas responsiveness to SF6, remaining unresponsive to any other gases. This design principle fundamentally eliminates false alarms caused by interference from other gases. Secondly, the instrument features an ambient SF6 gas zero-offset function (tare function). When the environment contains a baseline concentration of SF6, this function allows setting the ambient concentration to zero, preventing environmental gases from affecting test results and further reducing false alarms.
