Thermo Hygrometer PCE-444

PCE-444 is a combination digital hygrometer and digital thermometer for measuring air temperature, relative humidity, dew point temperature, and wet bulb temperature. Environmental conditions. Applications include climate monitoring of refrigerated trucks, warehouses, construction sites, and HVAC systems where excessive humidity, condensation, and uneven temperatures can cause mold, rot, and health hazards.

• Temperature units displayed in degrees Celsius (°C) and degrees Fahrenheit (°F)
• Minimum, maximum, and hold functions
• Easy-to-read backlit LCD screen
• Low-battery indicator
• Quick response time
• Automatic shutdown (can be disabled)
