Made to order to your spec — you choose the size and configuration.
This is a portable multi-gas detector built for confined, hazardous work — coal mine galleries, tunnels, utility vaults and any inspection route where combustible or toxic gas can accumulate. A worker clips it on or carries it on a sweep; it samples the air continuously and shows live concentrations on its display, with an audible-and-visual alarm the moment a reading crosses a threshold.
The sensor mix covers the four gases that matter most underground — methane (LEL combustible range), oxygen depletion or enrichment, carbon monoxide and hydrogen sulfide — and the accessory sets extend that to nitrogen dioxide and an infrared methane channel depending on the configuration you choose. An explosion-proof housing lets it run in atmospheres where a spark would be dangerous.
Simultaneous detection of methane, oxygen, carbon monoxide and hydrogen sulfide, with NO2 and infrared CH4 options
Combined audio and light alarm for noisy, low-visibility conditions
Explosion-proof metal construction for mine and tunnel atmospheres
Rechargeable 3.7 V battery sized for full-shift operation
Pocket-size body — single unit measures 70 × 40 × 20 mm, about 200 g
The unit measures methane, oxygen, carbon monoxide and hydrogen sulfide simultaneously. Depending on the accessory configuration you pick, it also covers nitrogen dioxide and an infrared methane channel, so you can match the sensor mix to the hazards on your site.
Is this gas detector safe to use in a coal mine or tunnel?
Yes. It has an explosion-proof metal housing designed for use in atmospheres where combustible gas may be present, which is why it is built for coal mine galleries, tunnels and other confined hazardous spaces.
How does the alarm work when gas is detected?
The detector monitors the air continuously and shows live concentrations on its display. When a reading crosses a set threshold it triggers a combined audible and visual alarm, so a worker notices it even in noisy, low-visibility conditions.
How long does the battery last on a shift?
It runs on a rechargeable 3.7 V battery sized for full-shift operation, so a single charge covers a typical inspection round. Recharge it between shifts to keep it ready.
What is the measuring range and accuracy?
The combustible channel reads 0–100 %LEL and the toxic/ppm channel reads 0–100 ppm, with a measurement accuracy of ±3 %FS. Specify the exact sensor configuration when ordering so the ranges match your gas targets.
Is shipping included in the price?
For in-stock items — anything you can add to the cart — shipping is included in the listed price. For made-to-order items, delivery is either free (marked on the product page) or calculated when you place your order, based on destination and volume.
How long does delivery take?
In-stock items typically arrive within one to three weeks. Made-to-order items take three to six weeks, since we work directly with manufacturers and need time for production and logistics before shipping. Your assigned manager confirms a more precise estimate once your order is placed. Please note we can't be responsible for delays caused by customs clearance in the destination country.
Are import duties and taxes included?
In most cases, yes — we aim to ship Delivered Duty Paid (DDP), which means duties and import taxes are handled so you don't face extra charges on delivery. In rare cases we may ship Delivered Duty Unpaid (DDU), where you would settle import charges directly with the carrier — but only when agreed with you in advance.
Do your products come with a warranty?
Yes. Most of our equipment comes with a one-to-two-year manufacturer's warranty covering factory defects and technical faults under normal use; the specific term is stated on each product page. If a defect appears, we arrange a replacement or refund in line with our Exchange & Return Policy, and our team guides you through the claim step by step.
