When should I replace the sensor filter on my ROBINAIR LD5 leak detector?

[AniyahAnn]

To keep your ROBINAIR LD5 Dual Mode Refrigerant Gas Leak Detector working at its best, it's important to know when to replace the sensor filter. The device itself will notify you when it's time; the display will show "REPLACE SENSOR FILTER." This usually happens when the filter looks dirty or after about 30 hours of use. Replacing the filter is easy: first, unscrew the sensor tip to get to the filter. Then, simply put in a new one. The LD5 keeps track of how long you've used it, so you don't have to. Regularly checking and replacing the sensor filter is key to accurate leak detection, helping you get the best performance from your ROBINAIR LD5.
