PCE-555 is a combination digital hygrometer and digital thermometer used to measure relative humidity as well as air temperature, dew-point temperature and wet-bulb temperature. This handheld multifunctional meter allows for quick and easy analysis of environmental conditions indoors and outdoors. Applications include monitoring of refrigerated trucks, warehouses, construction sites and heating, ventilation and air conditioning (HVAC) systems. PCE-555 is ideal for use anywhere excess moisture, condensation and uneven temperatures can create mold, spoilage and health hazards due to heat stress or poor indoor air quality (IAQ).
