Miniature probe can be placed virtually anywhere. Units incorporate fast response solid-state sensors. Monitor humidity with a resistive polymer sensor and temperature with a thermistor sensor. Feature a 2.9cm (1¹/₈") high LCD display that updates every second. Display temperature in °F or °C. Run continuously for 100 hours on one battery. Unit 33500-098 features dew point display and a programmable audible alarm.

Chemical-resistant ABS case is also shock-resistant. An O-ring prevents moisture, dust, and dirt from entering the case. For added protection, units are supplied with a carrying case.

Meet federal requirements for monitoring temperature and humidity in labs (CLIA specification 493.1207). Units are equipped with an RS-232 serial output socket for sending data to a computer.

A serial numbered certificate is provided from an ISO 17025 calibration laboratory accredited by A2LA to indicate instrument traceability to standards provided by the National Institute of Standards and Technology.
