When we first started offering gas detection technology in the mid ‘70s, the units seemed quite modern. Some models were able to detect two gases and didn’t need to be recalibrated more than once or twice a day.
Today we offer self-calibrating units that detect a range of gases for a variety of work environments and can run continuously for years. We have built this site to provide you with the most in-depth and up-to-date information about gas detection units and their capabilities.
The brands we offer have been vetted over the years by customer feedback and our own experience to provide you, the user, with the latest, most dependable technology, the best support and the best value for your money.
Our staff knows the nuts and bolts of our technology as well as the specifications. We are a
Factory Authorized Service Center of gas monitors for both RAE Systems and BW Technology by Honeywell. If your monitor needs repair or re-calibration, we can help.
Whether entering a confined space, assessing air quality in an office building or responding to a hazardous material spill, trained personnel make observations of the environment around them. In the case of gas detection, most of the hazards are beyond our ‘sense of smell’ to quantify. That is where portable gas detectors with substance specific and broad spectrum sensors step in. They extend our ability to ‘see’ the hazards around us and take appropriate action.
So what has allowed this evolution to occur? First is sensor technology. The Hydrogen Sulfide sensors we used in the ‘70s were larger than a 35mm film canister and had liquid acid inside that was used up as the sensor was used. This made the unit position sensitive, you had to keep it upright, and it used a lot of power. Not to mention that the sensor output varied as the acid was consumed. Now, an RKI Instruments H2S sensor is the size of a watch battery and is so trouble free that it is warranted for 2 years, and will be replaced free if it fails.
Then there are the electronics. Instead of a pointer needle on a sweep dial to give you readings, an energy efficient LCD screen shows you virtually everything you need to know at a glance, and far more with the press of a button. Underlying this are microprocessor chips that manage and store this information that may include temperature, humidity and time of day. But if the worker only need a ‘go - no go’ display, all of our instruments allow that as well.
The sensors and electronics have reduced the power needed; this has allowed us to use smaller batteries. Then the introduction of Lithium Ion rechargeable batteries, which replaced Ni-Cad, further enhanced the utility of maintaining an instrument. So for some users, having a single gas instrument the size of a
wrist watch, or a 4-gas monitor not much bigger than a deck of cards, is the answer to their needs. Of course not everybody wants small for the sake of being small. But now you do have the choice.
