TopTes Guard-101 Gas Detector, 4 Gas Monitor for H2S, CO, LEL and O2, with Vibration, Visual and Audible Alarms, 14h Long Battery Life, Safety Explosion-Proof, for Work, Home - Orange

I got this for home use for when I go under my house. I thought I smelled gas. It works great. For the price is well worth having around the house before you call the fire department. I highly recommend this.

I kept smelling gas at my Grandmother's house. I could smell it but Grammie couldnt. I called the gas company because this gas meter kept alarming. The gas company's detector wasn't picking up the gas and the gas technician couldn't smell it either. I kept insisting there was gas. This gas meter helped me convince the gas technician to keep searching for the leak. He finally found it and Grammie's house didnt blow up. Very thankful!

Worked right out of the box. Put it in front of my truck exhaust and it sounded a CO alarms immediately. Breathed into it and sound a O2 less than 20% alarm. I won't be so nervous in confined spaces.

Worked once...first time I used it was great. Then about a month and a half later went to use it again and it endlessly alarms on low oxygen even in the middle of an outdoor grass area with a good breeze blowing.

Worked as it should just would’ve liked it to have been a little more sensitive. I had the gas company out and they found a leak that this did not they have a better detector.

Part of my job is training new individuals for confined space. New individuals are often unsure of what they are doing. I wanted an air monitor that would work but also be expendible if the trainee would drop it or it would get misplaced in traveling to and from locations. I compared this unit to my name brand ones costing 5 to 10 times more expensive. Its actually significantly more accurate than i would have expected. I would actually reccomend this unit. Its a great value for a first air monitor. It was very easy to used and battery last forever.

Battery does not stay charged long. Have to keep entering pwd # to look at levels instead of it automatically displaying them all. Presets are not accurate. Book doesnt give enough information like charts of gas levels. Cant turn of pwd protect.

Muy buen detector

Use this in mines, caves, tunnels etc. Good piece of kit. Feel safe with this

Bon détecteur multi gaz

Bewertung: Der TopTes Guard-101 Gasmelder macht einen sehr hochwertigen und zuverlässigen Eindruck. Besonders überzeugend ist die gleichzeitige Überwachung von H2S, CO, brennbaren Gasen (LEL) und Sauerstoff (O₂) – das gibt ein hohes Sicherheitsgefühl, egal ob im beruflichen Einsatz oder privat. Die Alarmfunktionen sind hervorragend umgesetzt: Ton, Licht und Vibration sind klar wahrnehmbar und lassen keine Zweifel, wenn etwas nicht stimmt. Gerade in lauten Umgebungen ist die Vibrationsfunktion ein großes Plus. Die Messwerte werden gut ablesbar angezeigt und reagieren schnell. Auch die Akkulaufzeit von rund 14 Stunden ist praxisnah und ausreichend für lange Arbeitstage. Das robuste, explosionsgeschützte Gehäuse wirkt stabil und langlebig, die auffällige orange Farbe sorgt dafür, dass man das Gerät nicht so leicht verlegt. Fazit: Ein professioneller, zuverlässiger und einfach zu bedienender Gasmelder mit umfangreichen Sicherheitsfunktionen. Sehr gutes Preis-Leistungs-Verhältnis und klare Kaufempfehlung 👍

Works excellent. High quality gas detector! It detects when my elderly neighbor doesn't turn off her oven! Im adding photos of the manual, since the listing isnt too descriptive. Comes with hard case.

I have had no problems with this gas detector
