DESCRIPTION

Daigger® High Accuracy Hand-Held Thermohygrometers

High accuracy of ± 1.5% RH and ± 0.2° C

High display resolution of 0.01% RH

High/ Low settable alarms

Thermohygrometers accurately measure humidity, temperature and dew point. Program high/ low audible/ visual alarms for all parameters. Memory recalls both the highest and lowest readings in dew point, temperature and humidity at any time. When an out-of-range condition is sensed, an alarm sounds and the display flashes. Computer output through the accessory data cable permits data to be captured, transferred, stored and printed. Choose from the standard model or the fast-response model. Each model includes a probe with a 4.5′ cable, an NIST-traceable calibration certificate, one 9V battery and ABS carrying case.
