We sell a wide range of replacement parts for RKI gas detectors at PK Safety, including sensors, filters, batteries, and more. RKI makes some of the best fixed and portable gas monitors on the market, but you will likely need to replace certain components as they age or get damaged in the field. In many cases, you should be able to get your gas monitor working again by replacing these parts. This is much cheaper than buying a new detector altogether. We carry various RKI gas detection parts including chargers, NiMH batteries, vehicle plugs, filter disks for different sensors, and more.

You can test your gas monitor to make sure it is working properly by performing a bump test. If it fails the bump test, or you want to test for accuracy, a calibration test is necessary. Perform a bump test to ensure that the detector components are working properly, including the alarm and sensors. The test gas should trigger the alarm on the device, so you know that it will go off if it detects the target gas in your work environment.
Perform a calibration test to ensure that the sensors on the device produce accurate readings. Start by setting the monitor to zero. Insert the test gas into the gas monitor and compare the readings on the sensor to what’s listed on the target gas cylinder. If the monitor produces an accurate reading, the device is ready to use. If the readings on the monitor don’t accurately reflect how much gas is in the cylinder, you’ll need to recalibrate the device. If the device still does not produce an accurate reading, you may need to replace your sensors.
The battery on your device may also need to be repaired or replaced over time. Fixed gas monitors can run continuously for up to two years, but portable gas monitors usually need to be charged more frequently. The battery should last 24 hours or more — at least through a full work shift. If the battery doesn’t last as advertised, it may need to be replaced. You can buy replacement batteries and charging cables to resolve the issue.
Your gas detector is bound to get dirty over time, especially if you’re working in areas that aren’t meant for human occupation. Dirt and debris can damage your gas detection equipment and negatively impact your sensors. Workers should clean their equipment to prevent long-term damage. Solvents such as alcohol, paint thinner and the like should be avoided as they will negatively affect the sensors and could even poison them.
Use a cleaning solution made of 8 to 10 parts water and one part dish soap. Apply the solution to a dry, clean cloth. Use the cloth to wipe off any dirt and grime that’s collected on the surface of the device.
Use a cleaning solution made of 50 parts water and one part bleach to properly disinfect your devices. The solution removes bacteria and viruses that can lead to infection and illness.
Keep your gas detection equipment sanitary to reduce the spread of disease. Your workers should be able to use their devices without putting their health at risk.
It’s important to bump test your gas monitor at the start of each shift to ensure it will work in the field. Every worker should test this equipment before entering the work environment.
It all depends on what kind of gas monitor you’re using. Most 4-gas monitors that are designed to detect carbon monoxide (CO), oxygen (O2), hydrogen sulfide (H2S), and combustibles (EX) will last anywhere from four to five years.
However, individual sensors that test for CO, O2, and H2S usually only last for 24 to 36 months. These sensors degrade faster than the device itself, so be sure to replace them often.
Most RKI gas detectors come with a 3-year warranty that covers most repairs. You can send your device to a professional for gas detection calibration or servicing. Refer to the owner’s manual when replacing or repairing your device. Remember to thoroughly test your device after installing new parts to ensure they are working properly.
Use these spare parts to extend the life of your RKI gas detection equipment. If your devices need calibration or a diagnosis for a potential repair, PK Safety can help with our gas detector calibration and repair services. We are a Factory Authorized Service Center for RKI Instruments and our staff is directly trained by RKI.
