Traceable® Radio Signal Remote Humidity / Thermometer
By Control
- Monitors humidity and temperature up to 100 feet away
- Unit feature high/low alarms, °F/°C switchable
- Data is transmitted every 30 seconds
- Trend indicators show if humidity is rising or falling
- Additional Traceable Humidity/Thermometer Remote Sensor Module (Cat No. 291-4381); may be set to channel 1, 2, or 3; total of three modules may be used with main unit 291-4380
Traceable® Radio-Signal Remote Humidity Meter/Thermometer receives a radio signal from the remote wireless sensors, eliminating the cable. Place the main unit at your desk or bench. Place the remote sensor module in labs, ducts, and storage facilities—even outdoors. Remote sensor sends humidity and temperature signals to the main digital display. Transmits on a frequency of 433 MHz. Range is 65 to 100 feet, depending on the location or number of walls. Multiple main units must be more than 400 feet apart.
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.
Multi-point calibration on an individually-numbered Traceable® Certificate which assures accuracy from an ISO/IEC 17025:2005 (1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement.
Main unit can receive and display data from up to three different remote sensor modules. 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 for channel 1 only. 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.
