Split Type SF6 Infrared Quantitative Leak Detector

The MOEORW-WQL30 SF6 quantitative leak detector adopts non-dispersive infrared (NDIR) dual-wavelength sensing technology with built-in temperature compensation, eliminating cross-interference with miscellaneous gases. Equipped with high-precision AD sampling and high-speed CPU, the device delivers stable, fast and authentic SF6 concentration measurement data. A 4.3-inch TFT touch color LCD realizes visualized operation without radioactive sources, featuring low power consumption and a miniaturized integrated structure. It is an optimal measuring instrument for low-range SF6 leakage detection in power industry scenarios, with a service life up to 10 years for the infrared sensor module and minimal post-operation maintenance costs compared to electrochemical SF6 sensors.

Hardware & Structural Design

1.4.3-inch full-color TFT touch screen for intuitive graphical man-machine interaction;
2.High-speed single-chip microcomputer control system to process sampling signals in real time;
3.Built-in large-capacity storage module for mass measurement record storage;
4.Stainless steel sintered filter probe to prevent dust and contaminants from blocking the gas circuit;
5.Integrated battery level real-time display module for residual power monitoring;
6.Radiation-free infrared sensor unit, safe for long-term field operation.

Performance Advantages

1.Supports zero-point calibration and multi-point calibration for measurement accuracy correction;
2.Fast signal response, superior test repeatability and long-term measuring stability;
3.Strong anti-interference capacity, no cross-response to non-target ambient gases;
4.Sensor service life reaches 10 years, zero consumable replacement cost;
5.Miniaturized cabinet design, lightweight and portable for on-site mobile inspection.

Practical Application Values

1.Independent audible alarm system, buzzer continuous alarm when measured concentration exceeds preset threshold;
2.Integrated data storage, query, printing and time modification modules for complete test record management;
3.Built-in automatic self-calibration program activated upon startup without manual auxiliary operation;
4.Overcharge protection circuit for lithium battery to extend cycle service life;
5.Customizable alarm threshold ranging from 1 ppm to 200 ppm to match different site inspection standards.

1.Power grid GIS combined electrical equipment air chamber leakage inspection;
2.SF6 circuit breakers, inflatable switch cabinet regular leakage testing;
3.Power station SF6 gas storage equipment daily monitoring;
4.Low-concentration SF6 trace leakage detection for power operation and maintenance departments.

1.Power switching and charging operations are prohibited in hazardous flammable and explosive areas;
2.Avoid severe collision, extrusion and violent vibration during transportation and field testing;
3.Charge the device timely when battery indicator shows only 2 grids left; charging does not require power-on state, adapter red light indicates charging, green light represents full charge;
4.Keep the battery fully charged for long-term storage; inspect residual power regularly during idle periods;
5.Standard calibration cycle: full calibration every 2 years; half-year calibration mandatory for heavily polluted gas circuit working conditions;
6.Do not disassemble the internal calibration module without professional authorization; multi-point calibration function requires password entry for access.
