• Traceable*
• Reads °F and °C

This unit takes measurements across a wide humidity range. It simultaneously displays humidity and temperature. Memory switches display minimum and maximum readings of humidity and temperature over any time period. The HOLD button freezes the display to capture readings.

Miniature probe can be placed virtually anywhere. Unit incorporates fast response solid-state sensors. Monitors humidity with a resistive polymer sensor and temperature with a thermistor sensor. Features a 2.9cm (1 1/8") high LCD display that updates every second. Displays temperature in °F or °C. Runs continuously for 100 hours on one battery.

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

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

A certificate is provided to indicate instrument traceability to standards provided by the National Institute of Standards and Technology.

Also Includes: One complete carrying case, one 9V alkaline battery, instructions, and a probe with cable.

Pocket pen is ideal for monitoring humidity and temperature quickly and easily. Perfect size for laboratory or plant applications. Contains fast response solid-state sensors. Continuously and simultaneously displays relative humidity and temperature with dual recall memories. Temperature is displayed in °F or °C. Display is updated every second. Runs continuously for 6 months on one set of batteries.

Handy pocket clip makes the pocket pen easy to carry. Memory displays highest and lowest reading attained during a designated time period. High-impact ABS case is chemical resistant. A 1/2" high LCD display can be easily read at a glance.

Meets federal requirements for monitoring temperature and humidity in labs (CLIA specification 493.1207).

A certificate is provided to indicate instrument traceability to standards provided by the National Institute of Standards and Technology.

Provides humidity and temperature readings in an easy-to-read dial format. Ideal for constantly monitoring labs, fume hoods, walk-ins, plant areas, and storage facilities. Large, easy-to-view analog/readout displays 0 to 100% relative humidity and temperatures from –40 to 50°C (–40 to 122°F).

Self-contained, stable, and accurate unit requires no adjustment or maintenance. Complete with screw for wall mounting. Dimensions: 15.2Dia. cm (6") x 2.5H cm (1").

Thermometer readings are obtained by whirling the psychrometer. The psychrometer case is telescoped into the hand-holder to form a precisely accurate slide rule calculator of percent relative humidity.

Two thin-bulb thermometers with fast thermal response, 1° scale divisions, are clamped rigidly in the case.
