4 gas meter and pump

4 Gas Monitors

Easy to Use.

This is our basic 4 gas monitor with Pump setup by Forensics Detectors. The pump allows for point probe sampling or continuous sampling if one does not wish to enter the toxic environment or requires continuous controlled sampling. Easy to use and incorporates high-quality sensors, large LCD, and backlight.

USA NIST Traceable Source Calibration

Have the highest confidence in your gas detection accuracy. Possible only with best calibration practices to USA NIST Traceable Sources. Calibration of this oxygen detector is performed in the Forensics Detectors laboratory, located in Los Angeles, California, USA.

What is a 4 Gas Monitor?

A 4-gas meter measures gases such as carbon monoxide (CO), oxygen (O2), hydrogen sulfide (H2S), and combustibles (EX). When air quality is compromised, these devices are used for personal protection. Examples of hazardous gas environments include confined spaces such as tanks, vessels, silos, and tunnels. 4 gas monitors warn the user through audible, visual, and vibration alarms.

Gives an accurate reading of the levels of four gases. Will alert you to a level of carbon monoxide that is sufficient to make you sick, but insufficient to trigger a standard household alarm.

Works extremely well. Able to gas test the unit and with the addition of the external sample pump able to test various levels inside the confined spaces

Nice quality tool arrives with a calibration certificate. I selected this unit as a middle of the road replacement for another unit that had been stolen. I am very satisfied with this unit. Replacement parts and calibration services are local to the LA market which was also a factor in my choosing this unit. And the videos are great!

Seems solid enough, easy to use, battery packs were already charged, plug and play. Comes with certificate of calibration, and they recommend to send in for calibration every 6 months.

Our company has purchased several of these for green technicians as a way for them to be able to learn all aspects of a proper furnace maintenance and these work great for that particular use. Accuracy is not as spot on as I would have liked but that comes with the price point. Would still buy again for green techs and recommend it to them until they can afford the higher end tools.

I am an HVAC professional. I only use this item for explosive gas search and carbon monoxide detection. It is easy to use. The instruction are straight forward and the multigas detector seems to be as accurate as fieldpiece and sensorcon. I have zero complaints with this device.
