Overview

M40 • M coal mine specific 4 gas detector

Product Details

The 40 • M multi gas detector can be used in coal mines, mining operations, or other work environments to ensure that personnel are not harmed by oxygen deficiency (O2) and peroxide, hazardous gases (methane gas CH4), toxic gases such as carbon monoxide (CO), and hydrogen sulfide (H2S). This instrument has obtained the China Coal Safety Mark (MA). The M40 • M is equipped with a sturdy shockproof, impact resistant, and fire-resistant casing, providing ultra-high performance and durability in harsh environments, without being affected by radio frequency and electromagnetic interference. Its four key interface enables simple and sensitive operation and calibration, with a 5-second "delay" function to prevent accidental shutdown. Other standard features include: vibration and sound light alarm device, 75 hour data recording (black box) performance, lithium-ion rechargeable battery, peak/hold reading, large screen LCD display, and dedicated protective case. The compact integrated sampling pump (optional) can achieve remote sampling and detection within 15 meters.

performance	advantage
Small size, light weight, durable ABS chassis	The compact body also provides reliable performance without adding any weight burden to users. The device weighs 250 grams and can be held in the palm of the hand or clipped onto a pocket, helmet, or belt. The sturdy ABS construction provides long-lasting protection from damage caused by impact or drop.

lithium ion battery	Provides longer running time and allows for fast charging directly within the device.

Standard data recording function	The memory can record up to 50 hours of measured four gas concentration data (black box), which can be downloaded from a computer for easy operation management and accident liability determination.

quick-cal	Using Mcal can calibrate all sensors simultaneously, saving time. Compared to standard calibration procedures, this device can reduce the amount of gas required for each calibration, thereby saving costs.

Image format LCD display	The large screen LCD display provides synchronized readings of all monitored gases. The graphical operation icon displays the battery charging status, missing sensor conditions, and other related data.

Vibration alarm	Additional alarm functions can alert users in noisy environments.

Visual and auditory alarms	Bright indicator lights with visual alarms and 90 decibel auditory alarms can provide direct protection in hazardous environments.
