Review: Works great, sensitive, descrete readings, easy to use - This little meter works great. Used it to pinpoint a tiny natural gas leak at the back of a range, probably since it was installed two years ago. Well worth it. Appears sensitive (picked up natural gas at a level below what my wife and I could smell), has a nice digital readout, simple to operate. My wife and I would very occasionally smell a trace of gas near the range, but could not pinpoint it. The majority of the time we could smell nothing no matter how hard we tried, and assumed it was associated with the small amount of gas that would escape before the burners lit. I grew suspicious, and bought this meter. Immediately it detected the hotspot was where the range met the wall at the back. I pulled out the range, and the hose and valved looked new and in good shape. Further detective work with the meter narrowed it down to the connection at the valve. I unscrewed the hose and found that the installers didn't use tape or pipe thread compound! Added gas pipe tape, screwed everything back together, and all is good as confirmed by the meter. Nice product!

## Questions & Answers

**Q: Can this detector measure helium?  At what concentrations**
A: Not recommended for helium. Helium needs a special sensor.

**Q: UL listed?**
A: Think so but not 100% sure. Contact manufacturer of product.

**Q: Will this unit measure natural gas to levels as low as 2-10 ppm?**
A: The fact sheet states that the range is from 0-9999ppm, and the accuracy is 10% full scale.(Detectable gases Acetone, Acetylene, Alcohol, Ammonia,benzene,Natural Gas, etc.

**Q: Can the sensor be replaced ?**
A: Yes it can, but we do not sell these sensors. Time to replace, recalibration and sensor cost too high, more than a new unit.

### ⭐⭐⭐⭐⭐ Gas leak detector

This gas leak detector works very well

### ⭐⭐⭐⭐⭐ Worked Perfectly to detect a gas leak
*by J***N on September 24, 2021*

I had a slight gas leak from an oven which I was trying to locate. There was sometimes a faint smell of gas in the house. I could smell it from the back of the oven but I couldn't determine, using my nose, if it was a lose connection or a sticking valve. Originally I bought a cheap gas detector from the PANGAEA brand for $25. This had a range of 0 - 10,000 ppm but it's sensitivity was terrible. I zeroed it outside the house but the only gas it would detect was if I switched a burner on. This Forensics detector is amazing. I zeroed it outside the house again. As soon as I bought it inside the house it registered 70 ppm. It was sensitive enough that I could hold the sensor over the various connections and pin down the leak to the valve going to the oven and not the broiler. It's 4x the price but it works. The ability to zero the readings, switch the sensitivity between high and low and to switch the buzzer off are useful. It's small and feels good in the hands with the rubber finish. I wish the display was a bit brighter and I don't like that the battery compartment is held in place by a screw. This isn't going to be used very much so I don't want to leave the batteries in it all the time. Having to find a screwdriver to open the compartment is an inconvenience.
