The 70-2900-0570-4 from Macurco is a PM500-IR-NH3 multi-gas monitor with pump (O2/H2S/CO/LEL IR/NH3). Macurco's newest addition to the AimSafety portable gas solution lineup is the PM500 sampling type monitor. This rugged handheld, combined with a strong internal pump, can measure up to six gases simultaneously to allow for safe entry in confined spaces and hard-to-reach areas. PM500 monitors are equipped with audible, visual and vibrating alarms to alert the user of unsafe gas concentrations. The large backlit LCD provides sampled gas concentrations in real-time along with configurable alarm setpoints (low, high, STEL and TWA). Standard target gases include carbon monoxide (CO), hydrogen sulfide (H2S), oxygen (O2) and combustible gases.
