- This multi-gas monitor features a built-in 3000mAh high-capacity battery that surpasses most other devices on the market in terms of capacity, offering extended standby time.
High-strength ABS plastic
This gas detector is constructed from high-strength ABS plastic, ensuring durability and also water-proof, dust-proof, explosion-proof. Its non-slip concave design provides a secure and comfortable grip.
Multiple alarm function
When the detected gas concentration exceeds the preset alarm threshold, the gas data on the screen will immediately turn red, and the device will alert you through buzzer alarms, vibration, and warning lights.
Sturdy alligator clip
Equipped with a sturdy back clip, it is easy to carry and can be securely attached to clothing or belt during inspections, work, or assessments in confined spaces or toxic indoor environments.
4 Gas Monitor
This 4 gas detector features four sensors - a CO sensor (0-1000ppm), O₂ sensor (0-30% vol), H₂S sensor (0-100ppm), and combustible gas (EX) sensor (0-100% LEL). Designed for professional use, it delivers accurate gas concentration readings with rapid response times. Each sensor undergoes individual factory calibration, guaranteeing measurement accuracy and long-term stability in working environments.

This meter had typos and weird ranges for safe and dangerous levels. I don't trust that it actually works properly. It kept giving weird alerts for oxygen, even outside.

Use this in my garage in the winter when I've got my heaters running to make sure that I dont have any carbon monoxide issues

The quality of the 4 gas detector is superior, i have used gas detector all my life in my line of work and I am very impressed with accuracy of this multi gas detector monitor.I have used plenty of time since received.It come already calibrated and certified as well.The two modes available makes versatile, the lock screen is something I really like as it prevents it from being activated accidentally.USB capability, excellent manual, so much more!

The 4-in-1 gas detector has a bright orange housing with a USB-C charging port on top, a clear 2-inch display screen, and a metal clip. I can switch from the pump suction to natural diffusion by removing four screws from the rear. This detector simultaneously monitors four gases: oxygen concentration ranging from 0 to 30%, flammable and explosive gases measured from 0 to 100% LEL, hydrogen sulfide levels up to 100 ppm, and carbon monoxide concentrations up to 1000 ppm. On the back I read it's powered by a built-in rechargeable 3000 mAh Li-ion battery, and the device meets EU standards with its CE certification logo on the back. When I start it up, it does a self-test followed by a 10-second preheat sequence before entering active detection mode. When I see two green LEDs flashing periodically I know the readings are within safe levels. The display is small but the sharp screen has a simple menu navigation through up/down buttons and a power button. I can view real-time gas concentrations in graph format and go over the alarm history log. The menu system provides control options, allowing me to adjust alarm thresholds for each gas, implement password protection, look up device information, and configure various settings including time, date, backlight duration, language, and pump parameters. The detector comes with a few accessories, including two sampling hoods, air tubing, a USB-C cable, and a charger. For me, the carbon monoxide detection is the most important, as I can't see nor smell this dangerous gas.

Having used 4 gas detectors for a number of years I have grown pretty accustomed to them. While this looked like a good value detector on the surface, in function it is a failure. The manual, as should any 4 gas detectors, tells you to calibrate the device before use, but the calibration menus require a passcode to get into them, that isn't supplied and I can't find anywhere. These leaves me unable to even calibrate it for use, which raised another concern. The exposure levels that this meter uses to trigger unsafe alarms are far higher than OSHA or any other safety governing organizations I have ever seen. Some are so high they are outright hazardous to your health well below the alarm is set to sound.

Perfect for safety. I use this when I have to go in an atmosphere that doesn’t have monitoring so I can ensure that I have safe, breathable air. I never know what I may walk into so this works well as it stays clipped onto me and alerts to unsafe conditions.

This gas detector feels heavy and is easy to use with clear readings, shows gas levels in real-time, can view records and curve.

Nice little meter. Easy to operate and easy to read. Glad they included a manual but the print is tiny so be prepared. Overall use is good, easy to figure out, highly recommend as it's a handy dandy little tool for your box.
