Traceable® Hygro./Therm./Baro./Dew Point Pen - Each

• Portable - Easy operation
• Quick response
• Minimum and Maximum Memory

Measures temperature, humidity, barometric pressure, and dew point. Relative humidity range is 10.0 to 95.0% with a resolution of 0.1% and an accuracy of +/-3% RH mid-range to +/-4% RH elsewhere. Temperature range is 32.0 to 122.0°F and 0.0 to 50.0°C with a resolution of 0.1° and an accuracy of +/-1°C. Dew point range is 13.5 to 120.1°F and -25.3 to 48.9°C with a resolution of 0.1°.

Barometer measures pressure in 3 different units: Inches of mercury (inHg) from 0.29 to 32.48 with a resolution of 0.01, millibars (hPa) from 10.0 to 1100 with a resolution of 0.1 and 1 hPa, and millimeters of mercury (mmHg) from 7.5 to 825.0 with a resolution of 0.1 mmHg. Accuracy is +/-4 hPa between 550 to 1100 hPa. User selectable dual display shows humidity/temperature, humidity/dew point, barometer/temperature, or barometer/humidity.

Compact design features an electronic capacitance polymer film sensor not affected by condensation. Tough ABS plastic housing and water-resistant design with O-ring seal and membrane keypad assure a long life in severe lab or harsh plant environments. HOLD button freezes the reading on the display. High contrast 3/8-inch-high LCD digits are easy to read. At the press of a button, unit recalls minimum/maximum readings.

To assure accuracy an individually serial-numbered Traceable Certificate is provided from Control Companys ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Rugged ABS plastic case is 1-1/2 inch diameter x 8 inches; weight is 5 ounces. Supplied with a Traceable Certificate, metal clip and four AAA batteries. Replacement battery Cat. No. 350-19942.
