E40 portable multi-gas detector (hereafter referred to as the detector) is a type of intrinsically safe equipment for continuous detection of combustible gases, oxygen, carbon monoxide, and hydrogen sulfide.
Quote NowE40 portable multi-gas detector (hereafter referred to as the detector) is a type of intrinsically safe equipment for continuous detection of combustible gases, oxygen, carbon monoxide, and hydrogen sulfide. It is suitable for explosion-proof and toxic gas leakage prevention, underground pipelines, or mines, effectively ensuring the safety of workers and protecting production equipment from damage.
The detector employs natural diffusion for gas detection, featuring high-quality gas sensors with exceptional sensitivity and repeatability. Its embedded microcomputer control system ensures simple operation, comprehensive functionality, and high reliability, while offering multiple adaptive capabilities. The user-friendly interface and compact, aesthetically pleasing portable design make it both an indispensable tool and a convenient companion for on-the-go use.
The detector shell is made of high strength engineering plastic and anti-slip rubber, which is waterproof and dustproof.
The instrument employs an advanced ultra-low-power 16-bit microcontroller.
The ultra-wide viewing angle display interface has the advantages of clear display, rich content and wide temperature range.
Multi gas detection to meet the requirements of special testing scenarios
The combustible gas sensor has high concentration protection;
with sensor fault self-test;
The system has the function of self-test and self-repair.
Automatic calibration function to reduce detection error;
Two-level triple alarm (sound, light, vibration) is not easy to ignore;
Toxic gas also has STEL and TWA alarms;
It allows convenient monitoring of STEL, TWA, and peak concentrations since system startup.
Battery low voltage alert with charging management feature
Provide real-time clock display;
Anti-slip design, durable and strong;
Intrinsic safety instruments.
It is suitable for explosion-proof and toxic gas leakage prevention, underground pipelines, or mines, effectively ensuring the safety of workers and protecting production equipment from damage.
