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.
|
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. |
