RKI Instruments

RKI Instruments is partnered with Riken Keiki Co. Ltd. to provide leading gas detection and systems that serve workers in confined spaces, marine oil industrial settings, hospitals, LACT units, and more.

One of RKI Instrument’s advanced gas detection equipment is the HS-04 series H2S single gas monitor. It’s one of the world’s smallest and lightest single-gas monitors. 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.

The HS-04 series is designed to monitor the worker's breathing zone and can operate for up to 3,000 hours, and has a warranty of three years.

For a configurable option, the RKI GX-6100 4-gas monitor is a solid choice. Its sensors can detect volatile organic compounds, oxygen levels, hydrogen sulfide, and carbon monoxide and it features a strong internal sample pump. It is durable, low-maintenance, and has varied warning systems to make sure the message gets across. 

For the budget-conscious, the RKI GX-3R 4 gas confined space 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 Instruments. We also have other calibration kits from RKI Instruments 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 is a factory-authorized service center with our in-house technician ready to help. We also maintain a large stock of replacement sensors and parts from RKI Instruments for various hazardous gases, filter disks, adapters, pumps, tubes, gas cylinders, calibration stations, stand-alone monitors, and other specific gas monitoring applications.

Innovative gas detection technology 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 Instruments 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 Instruments has solutions for your gas detection needs, and PK Safety has the expertise to help you find the right solution for your work.
