OMEGA HHTP21 Timer Counter, 0 °C, 60 °C, 1, 1 to 99% RH

HHTP21 particulate meter and particle counter is ideal for monitoring particulate pollution in department stores, burning plants, petrochemical facilities, thermal power plants, restaurants, hospitals, mining facilities, metal refineries, commercial and public buildings.
