An abdundance of features combine to create the perfect laboratory clock. View temperature and humidity readings from anywhere in the lab.

• Giant-Digits™ 4.75" display is viewable from 200 feet
• Simultaneously displays both F/C temperatures and relative humidity
• Temperature range: 0 to 45 °C (32 to 113 °F); Resolution: 0.1°; Accuracy: ±1 °C
• Humidity Range: 20 to 90% RH; Resolution: 1% RH; Accuracy: ±5% mid-range (±7% otherwise)
• Accuracy is ¹/₁₀₀₀₀ of a second; Maintains better than 1-second accuracy for 25000 years
• 1 second resolution

Unit features a radio signal from NIST’s Colorado atomic clock to automatically set correct date/time. A calendar displays month/date, and day. Additional features include alarm, temperature and humidity display, and desk and wall mount supplies.

Individually numbered Traceable® Certificate assures accuracy from an ISO/IEC 17025:2005 (1750.01) calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (national Institute of Standards and Technology).
