Review: Good option compared to big brands - So it is good, and absolut priceworthy. If you are questioning weather it's reliable or not it is, I'm working withing telecom and have to use a GRU in the chamber for testing gases. There was a small gasleak at one of the entry points. And ingot the same reading on this one as my high end brand gdu 10-12% lel. This one has the benefit so with more options and parameters and so the logo history easily accessible for alarm dates. Just make sure that you set alarm levels to your industry standards as they are on factory defaults. Good and easy usb charge a, Downside is being mini USB that is uncommon but still easy to find a spare
Review: Works well, easy to use - An essential tool for those in the trade. A 4-gas meter measures gases such as carbon monoxide (CO), oxygen (O2), hydrogen sulfide (H2S), and combustibles (EX). Essential for personal safety. When the air quality isn't safe, 4 gas monitors warn the user through audible, visual, and vibration alarms. Works very well but bump testing and calibration are necessary. I like that it has a long battery life, a large screen that displays gas concentrations, and a belt clip to connect to clothing. It is robust and a good safety tool for those working and assessing a confined space or toxic indoor space.

### ⭐ Absolutely poor quality
*by L***A on 4 January 2024*

Honestly this is awful. Device came dirty, did not have any calibration certificates and measured 0ppm CO2 when placed in a 20% CO2 incubator 🙃. Instructions are also just taken from Google translate or something because they make no sense Edit: wanted to add this edit because I realised I made a mistake in my original review. So, I used this in a high CO2 incubator, the increase in CO2 reduces the O2 percentage. The O2 value on this machine didn't change. Infact it didn't change no matter where I used it. Also, in a high CO2 incubator, the CO increases, but on the monitor, this reading didn't change from 0 either. I will say though that the seller did sent through the calibration certificate, but since the monitor isn't working this wasn't helpful.
