IR-AH Series Handheld Type Digital Radiation Thermometers

Data_Sheet
The IR-AH series is non-contact handheld type digital radiation thermometers for the measurement of temperature. The thermometers have features of a wide measuring range from -50°C to 3000°C, digital displays of the measured value in the finder and on the panel board, and storing function of the measured data. An RS-232C port is provided to transmit the measured data to a personal computer. With a Data Logging Software (sold separately) , you can analysis and manage the measured data.

Features

  • Data storage
    Maximum 1000 data can be stored. The data stored are readable on the display with index numbers for easy classification of data.
  • Easy-to-read internal and external digital display
    A measured value is digitally displayed in the finder and on the panel board.
  • RS-232C port
    The communications interface port (RS-232C) is provided to transmit the measured data to a personal computer.
  • Signal modulation
    Measurement modes of real value (real) maximum value (peak), average value (delay) and minimum value (valley) are selectable for measuring purposes.
  • Data logging software
    The data logging software is separately prepared for the analysis and management of the measured data.
  • Analog output (option)
    The analog output of 0 to 1VDC is offered at an optional specification. By using an AC power adapter (option), the continuous measurement enabled.
  • Other functions
    Various functions including high/low alarms, °C/°F selection, auto-power-off, battery check and user's calibration (zero/span) are available.
  • CE
    All models are complying with CE.
