RKI Portable Single Gas Monitors

RKI Portable Single Gas Monitors

RKI Instruments makes several single gas monitors that are great for a variety of gas detection programs and  each monitor is equipped to detect the presence of a single target gas, such as hydrogen sulfide, carbon monoxide, oxygen, ammonia, and combustibles that can cause a flash fire. If the worker needs to detect a range of gases, they will need to use a multi-gas detector instead.

The single gas monitor’s sensor detects the amount of gas in the air and if the quantity of hazardous gases in the air surpasses the acceptable limit, the sensor will alarm, so the user can either ventilate or evacuate the area to prevent exposure. Most alarms issue an audible, visual, and vibrating signal for maximum employee awareness.  

Portable single gas monitors are designed for continuous monitoring. Most devices operate using either two alkaline batteries or a rechargeable Ni-MH battery. Battery life depends on the make and model, but every device should operate continuously for at least 16 hours, giving each worker enough time to complete their shift. 

RKI Instruments has a long reputation for making quality and reliable gas detection equipment. These monitors are used by professionals in various industries, including firefighters and first responders, utility crews, safety inspectors, and oil and gas workers. 

How long are gas monitors good for?

The sensor on the single gas monitor should last between two to three years. Workers can replace the sensor to extend the life of their device. 

Select RKI portable gas monitors come with warranties that cover the cost of repairs. Users will need to bump test the device before each shift to ensure it’s working properly. If it fails the bump test, calibration will be necessary. We recommend calibrating at least every six months to ensure the device produces accurate readings. 

How much does a gas monitor cost?

Single gas monitors cost between $125 and $500, depending on the sensor and model. Small, compact devices tend to cost less than heavy-duty instruments. Some competing single gas monitors may cost less, but they typically won’t last as long.. Replacing this equipment may exceed the cost of buying a more durable monitor that will last for several years. 

Where should I place my gas detector?

Users should place their device in the breathing zone, or the ten-inch radius around a person’s nose and mouth, to ensure the monitor is taking in the same air the person is breathing. 

Most monitors come with a clip that makes it easy to attach the device to the person’s collar, lapel, or bag. RKI even has the GasWatch line where your single-gas monitors can be worn on your wrist. Workers can also clip the device to their hard hat to keep it out of the way. Every portable RKI monitor is lightweight and compact to keep workers mobile in the field.
