Handy type Digital PH Meter SK-620PHII (with standard probe PHP-31)

Model
SK-620PHII
Handy type digital pH meter. PHP-31 standard probe is attached. Various optional probes are provided for wide application. Measured data can be transmitted to a PC in real-time via RS-232C. AC adapter is available at option.
* This model is not usable for certification purpose

  Features

  • Standard probe PHP-31 is attached as a standard accessory
  • Various sensors are provided. Available to select the probe suitable to your application
  • Three points calibration
    Calibration points (at 25°C) : 4.01, 6.86 and 10.01
  • Auto Power-Off
    The "Auto power-off" function turns off the unit 20 minutes after the power is turned on.
    This conserves battery life if you forget to turn off the unit.
  • Auto temperature compensation
    Once the PHP-31 sensor probe is connected to your SK-620PHII, it will perform automatic temperature compensation to produce more accurate pH measurements.
  • Backlight function when used in the dark place
  • Measured data are transmitted to a computer in real-time by RS-232C output  (RS-232C cable is optional)
  • Continuous measurement is available with AC adapter
  • Vinyl cover to protect the main body against water is attached
