    • Exposed Temperature Sensor
      Exposed temperature sensor allows for quick Automatic Temperature Compensated measurements. Temperature can be displayed in either oC or oF.
    • Graphite Sensor
      Reduces polarization effects and does not oxidize resulting in a reliable and accurate reading.
    • Automatic Calibration
      Automatic calibration at 1382 ppm (mg/L) with a single push of a button.
    • Stability Indicator
      A clock tag stability indicator will disappear to alert the user when the reading is stable.
    • Automatic Shut-off
      User-selectable time until meter shuts off to conserve battery life. Options are 8 min, 60 min or disabled.
    • Low Battery Indicator
      Low battery indicator that is displayed when less than 10% battery life is remaining.
    • Battery % Level at Startup
      At start-up, all the LCD segments are displayed for 1 second, then the percent indication of the remaining battery life is displayed
