Review on 🔥 Portable 4-Gas Detector Alarm Handheld: O2, H2S, EX, CO. Professional Gas Monitor Analyzer Sniffer Meter Battery Operated (Black) by Jerry King

We live in an old house and from time to time it smells interesting, especially in our basement. or explosive (natural gas), so I took this PDA. Detector. The device looks well made. The instruction manual is poorly translated into English and was difficult to understand even for me as an engineer. I finally made it, long enough to get the device working and get useful information out of it. watch the video The box contains a detector, a micro-USB cable for charging, a USB plug for a socket and a strange cover for sensors on the front, which is not described in the instructions ... at least I could not find it. This poor translation carries over to one of the main gas monitor displays where "unit" is misspelled as "uint". watch the video Seems to be a decent product. After an overnight charge, it lasted 10 hours on the first charge. I hung it by a ring at the back where some odors accumulated, the stairs led down to the basement and was assured there were no explosive gases present (EX refers to propane). and natural gas). Since one of the problems with testing an emergency detector like this is that you're not usually in an emergency, I backed up what I called low O2 by breathing on the sensors. The normal ambient O2 is 20.9% and the normal exhaled O2 is about 17%, so I could easily induce anxiety. It also allowed to see what the charts look like. See video. In addition to the ring, there is a clip on the back that can be attached to a small hose or even a belt or harness, allowing the detector to be carried around the neck on a lanyard or elsewhere when entering an unfamiliar environment. .Units, time, etc. can be changed. Like most things, the manual is very cryptic. You must bring up a screen where you can enter a password and then enter 1111. This will bring up the system screens shown in the video. A useful point written in the manual: when an alarm sounds, it can be turned off by pressing the "OK" button twice. So I am satisfied with this product. It's expensive and made by a brand I'm not familiar with (Honeywell for example), but the fact that I can exhale to alarm it gives me confidence it will work. I plan to test it next to a propane tank with the valve ajar for a short time and also test the EX sensor. In addition to O2 and EX, other sensors are H2S (hydrogen sulfide) and CO (carbon monoxide). So I can recommend this product. It loses 1 star for a poorly translated user manual and a clunky user interface (UI).
