  • Noncontact temperature measurement
  • Continuous measurand output of the thermopile to the LCD
  • Adjustable emmissivity, to adapt to different surfaces
  • Pyrometer is laser assisted
  • Configurable condensation/dew alarm with contact-free measurings (Application: e.g. detect molds)
  • Two lines color display with large digits
  • Accurate measurement of temperature and relative humidity
  • Calculation of dew point temperature of the ambient air
  • Calculation of mixed ratio
  • Display of MAX, MIN, HOLD, AVG and ACT, easily selectable
  • Easy-to-use touch operations (capacitive)
  • USB interface for SmartGraph3 software
  • Calibration certificate


The powerful and compact handheld device with state-of-the-art and robust design. Excellent accuracy. The high-resolution color screen displays rel. humidity, temperature and dew point. Excellent readability. The calibration function (offset correction) guarantees the long-term use without compromising the accuracy.
Supplementary description:
