## Description

Multigas 4 Gas Monitor | with USA NIST Calibration Certificate | CO, H2S, CO, EX LEL |: desertcart.com: Tools & Home Improvement

Review: It works perfectly - I am vetting inspector working on board ocean going Petroleum and Gas ships. As a part of my job and to be a good role model to the ships crew, I carry this personal gas detector with me. I bought it 3 months ago. It works perfectly. Battery - I use it for about 3 hours every ship and it lasts about 3 ships ebfore recharging. I also like that it has a usb recharge and no need to carry a separate bulky charger. It clips on the boiler suit pocket. It also looks very stylish. It does the job from the safety point of view. It arrived with a calibration document valid for 12 months. I highly recommend it.
Review: Continues to work well. Better than expected, and without the higher price tag - I was in a bind looking for a 4X monitor to use at a job site for a site engineer. I did some research and chose this one instead of another major brand. For half the price, this is a great option. It's not just a compliance item, but a reliable tool people can use with trust.

## Questions & Answers

**Q: when measuring oxygen readings, can you set a range of time, duration or frequency for data logging?**
A: Great question, see video for a detailed answer.

**Q: will this unit pick up propane and natural gas leaks during a home inspection?**
A: This is not made to pick up leaks during a home inspection. What would be more appropriate is a gas leak detector with GOOSE NECK. The gas leak detector is more sensitive (in ppm) range where this detector is a LEL % detector, for exposure safety purposes.

**Q: Does this 4 gas detector come with a clip to attach to my FR shirt?**
A: The detector has installed on its back a belt clip. Thanks

**Q: Is there a calibration kit available?**
A: The detector comes with a calibration cap to be plugged into calibration gas.
 For calibration, a standard mixed gas NIST gas bottle with a regulator will work very well. Our recommended product is ASIN: B015O16X32.
Multi Calibration Gas: 25 PPM Hydrogen Sulfide, 100 PPM Carbon Monoxide, 2.5% (50% LEL) Methane, 19% Oxygen, Balance Nitrogen
