    Gas Detection

    Multi-gas monitors, photoionization detectors and single-gas personal monitors for fire, HAZMAT, confined-space and industrial work. What separates FarrWest from a catalog reseller is what happens after the sale: we calibrate, bump-test and repair detection instruments at our own Texas depot, so your monitors do not leave the state or sit in a queue for weeks. Ask about scheduled calibration contracts and loaner instruments that keep a crew in service while their unit is being worked on — for most departments that is the difference between a compliance programme that runs itself and one that quietly lapses.
