Simple operation
Measurement can be started just after power is ON without any set-up.
Serial number and calibration date (year and month) are indicated on LCD when the power is turned ON
There is no seal sticking to the unit to prevent contamination such as peeled seal at the time of measurement.
The serial number of the unit and the traceable calibration date are displayed when the power is turned on. It is easy to manage records on site.
Note: Only the unit calibrated at our laboratory is available to indicate calibration date. User cannot input the calibration date.

Display example:
  Serial number     Calibration date (year and month)

HOLD function, Auto power-off function
HOLD function:
Measured value can be held. This function is usable to read the value easily when the temperature changes too frequently during measurement

Auto power-off function:
The power will be turned off automatically if the unit is not operated for approx. 60 minutes. Even if you forget to turn the power off, this function conserves battery power (this function can be released)
Resistant body to water, impact, heat and alcohol
Material of the body is polycarbonate resin that offers resistance to high temperature, impact and alcohol in comparison with ABS resin so far use.
The body conforms to JIS C 0920 IP67 and it is available to wash the body in running water and wipe with alcohol. (when the unit is connected to a probe)
* Material of display section and key pad is PET resin.
Durable body and easy-to-read display
Rubber around the side of the reduces the damages due to falling. The slanted back improves the visibility of display.
Front Rear
Available to issue the calibration certificate, traceability diagram that require for the management of measuring instrument under ISO and so on.
