RKI GX-3R 4 Gas Confined Space Monitor 72-RA-C



RKI GX-6000 PID Gas Monitor - Super Toxics 6 Gas Monitor 72-6AB


One of RKI’s innovative gas monitor options is the GasWatch 3. It’s one of the world’s smallest and lightest single-gas monitors, and while you can wear it on your wrist like a watch it can also be clipped onto your lapel, hard hat, or other gear with its alligator clip. It can operate for up to 4,000 hours, last up to two years, and comes in five versions: CO, H2S, O2, CO/O2, or H2 compensated CO. PPE that’s inconvenient to use won’t get used and won’t be able to do its job, which is exactly what makes the easy-to-use GasWatch 3 such a great tool.

For a configurable option, the Eagle 2 is a solid choice. Its sensors can detect volatile organic compounds, oxygen levels, hydrogen sulfide, and carbon monoxide, and it comes with the accessories and equipment you need to take samples remotely—a crucial feature for making sure you know about toxic or other hazardous conditions in advance. This is an easy-to-use monitor, even while wearing gloves, and is durable, low-maintenance, and has varied warning systems to make sure the message gets across. For the budget-conscious, the GX-2009 Portable Multi Gas Detector & Monitor is a comparable alternative for measuring the standard four gases.

If you need some of everything, PK Safety also has complete confined space kits from RKI. The GX-3R 4 Gas Confined Space Kit has the GX-3R 4-gas monitor, accessories, and everything you need to calibrate it all in one case; the GX-2012 Confined Space Kit has a case that contains everything you need to bump test and calibrate the included GX-2012 Multi-Gas Detector. We also have other calibration kits for other monitors available and a padded carrying case to store the gear that you already have.

Of course, that’s not all that PK Safety has to offer from RKI Instruments. In addition to confined space monitors, detectors, and complete kits, PK Safety has everything you need to keep your team safe and the experts to help you find your ideal PPE. RKI replacement sensors for various gases, filter disks, adapters, pumps, tubes, gas cylinders, calibration stations, stand-alone monitors, and other supplies that you need from one of the brands we trust most.

Innovative gas monitors and gas detection equipment saves lives and protects property from gas and vapor hazards. They’re an essential part of PPE across an array of industries, and you shouldn’t go into a confined space or hazardous atmosphere without one. RKI has created monitors that will provide gas protection for life: with proper care, these may be the last gas monitors that you ever need to purchase. RKI has solutions for your gas detection needs, and PK Safety has the expertise to help you find the right solution for your work.
