Multifunction Wireless Thermometer/Hygrometer with Three Remote Sensors

Monitor temperature and humidity in multiple locations from one convenient display.

This multifunction thermometer and hygrometer includes a main console with a built-in sensor and three wireless remote transmitters, making it ideal for offices, laboratories, storage areas, workshops, greenhouses, warehouses and other indoor environments. The comprehensive LCD displays indoor and remote temperature and humidity readings, recorded minimum and maximum values, environmental trends, time, date, and day of the week. Each remote transmitter also has an LCD for viewing measurements directly at the monitored location.

Programmable upper and lower limits provide immediate notification when environmental conditions move outside the selected range. The receiver uses color-coded alarms to make out-of-range conditions easy to identify. Real-time trend indicators show whether temperature and humidity are rising, falling, or remaining stable, helping users recognize changing conditions at a glance.

Constructed from durable ABS material for dependable, long-term use, the system provides wireless transmission at distances up to approximately 328 feet (100 meters) in unobstructed areas. Temperature units can be switched between Celsius and Fahrenheit with the press of a button.

Package Includes: One main display console, Three wireless sensors/transmitters, USB power cable, Users manual, (9) AAA Batteries.
