Handheld Combustible Gases Leak Detector Natural Gases Leakage Tester Portable PPM Meter Combustible Gases Detection Tool 4 Concentration Indicators with Sound and Light Alarm ( Item#: E22598 )

This combustible gases leak detector is a fully intelligent gases detection alarm designed with digital technology, with high stability, communication and self-diagnosis capabilities, ease of use and maintenance that greatly meets the requirements of a high-reliability device for industrial field safety monitoring. Combustible gases leak detectors are widely used in petroleum, chemical, metallurgy, refining, gases transmission and distribution, and other industries and enable on-site detection and alerting.

Features:
Portable gases detector, compact body, quick response to quickly detect leaks.
The housing is made of high-strength ABS engineered plastics, which is dust-proof, blast-proof, splash-proof and has a long service lifespan.
There are antislip textures on the sides of the housing, and also has comfortable buttons, and heat-emitting holes.
Quality high-sensitivity sensors, with built-in temperature compensation and calibration coefficients, are characterized by high accuracy and linearity; Provides high stability and response recovery speed.
The extended flexible probe, with flexible adjustment of the arcs, is suitable for a variety of special scenarios.
Built-in simple calibration, automatic calibration and zeros-back and automatic compensation programs.
4 concentration indicator design, where different indicators correspond to different detection values from high to low.
A bright LED indicator displays the power supplying and prompts the battery status for replacement.
The sound-and-light alarm design prompts a concentration indicator and a buzzer to sound an alarm when combustible gases reach an alarm value.  ​Radiation resistance and electromagnetic interference to reduce false alarms.
Extensive application scenarios meet the detection needs, suitable for petroleum and petrochemicals, natural gases, gases pipeline detection, kitchen gases detection, restaurants and hotels, chemical plants, gases tankers, etc.
