Traceable 4380 Offers

Displays Humidity and Temperature from 100 Feet Away
Transmits on a frequency of 433 MHz. Range is 65 to 100 feet, depending on the location or number of walls.

Traceable to NIST for Accuracy

Relative humidity range is 25 to 90% with a resolution of 1% and an accuracy of ±2% RH mid-range to ±4% RH elsewhere. Switchable thermometer range is –4 to 140°F and –20 to 60°C, with a resolution of 0.1° and an accuracy of ±1°C. To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).

Displays up to Three Modules

Main unit can receive and display data from up to three different remote sensor modules. Data is transmitted every 30 seconds. Display's trend indicators show if humidity and temperature are rising or falling. Minimum and maximum memory display allows monitoring of conditions over short or long periods, including overnight or weekends. An alarm may be set in increments of 1% RH and 1°. The alarm sounds when the humidity or temperature exceeds the high and low set points. Jumbo digits (1-3/8-inches-high) may be read from 25 feet. Cases are high-impact, chemical-resistant ABS plastic. Furnished with a flip-open stand, wall brackets, and Velcro™ to attach to any surface. Batteries operate continuously for eight months.

Supplied complete with Traceable® Certificate, one main unit (4-1/4 x 4-1/2 x 3/4 inches, weight is 6 ounces), one remote sensor module (2-1/3 x 3-1/2 x 3/4 inches, weight is 3 ounces), internal humidity sensor, internal temperature sensor, and alkaline batteries.
