Control Company 4380 Humidity Radio Signal Remote Traceable Thermometer (Discontinued)

FEATURES

• 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. 4381); may be set to channel 1, 2, or 3; total of three modules may be used with main unit 4380

DISPLAYS HUMIDITY AND TEMPERATURE FROM 100 FEET AWAY

Traceable® Radio-Signal Remote Humidity Meter/Thermometer receives a radio signal from the remote wireless sensors. It eliminates 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.

MAIN UNIT

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.

REMOTE SENSOR (INCLUDED)

Relative humidity range is 25 to 90% with a resolution of 1% and an accuracy of ± 5% midrange, ± 7% otherwise 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.

TRACEABLE® CERTIFICATE

Multi-point calibration on an individually-numbered Traceable® Certificate which assures accuracy from our 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.

DISPLAYS UP TO THREE MODULES

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.
