RH/Temperature Indicator

RH/Temperature Indicator
±1%RH
  • ± 1% RH (0-90%), ± 2% (90-100%)
  • Measures temperature from -40 to + 212° F (up to 356°F for short periods)
  • Calculates dewpoint, wet bulb temperature, absolute humidity and mixing ratio
  • Serves as an easy-to-use field calibrator
  • Data collection capability, with serial line download to PC

This hand-held indicator can be used for spot checking humidity and temperature in cleanrooms, HVAC systems, storage enclosures, and environmentally sensitive areas.

In addition to displaying %RH and temperature readings, it also calculates dewpoint and wet bulb temperature, absolute humidity, and mixing ratio, freeing you from awkward conversion tables and complex calculations. The indicator features an easy-to-read two-line liquid crystal display, with metric and non-metric readout.

The Temperature/Humidity Probe features a stainless steel head made to withstand rough handling. The probe’s long shaft is perfect for cramped, inaccessible spaces. The HUMICAP® sensor provides high accuracy, excellent long-term stability, and negligible hysteresis. It is insensitive to dust, particulates and most chemicals.

This easy-to-use instrument offers fast response time, high measurement accuracy, excellent stability, and a wide measurement range, making it ideal for field calibration and other demanding applications.
