Hanna Combo pH/EC/TDS/C/PPM Tester HI98129

  • 3 sensors in a single tester pH electrode with extractable junction. Amperometric EC/TDS sensor. Exposed temperature probe for faster EC and TDS (ppm) readings
  • Waterproof Designed to float if accidentaly dropped in sample
  • Wide pH Range pH range is from 0.00 to 14.00 pH
  • Selectable EC to TDS (ppm) conversion factor Choice of either a 0.45 or 1.0 conversion factor
  • Automatic Temperature Compensation All readings are compensated for variations in temperature
  • Temperature displayed in oC or oF along with pH, EC or TDS reading
  • Stability indicator Meter displays a clock tag that will disappear when the reading has achieved stability
  •  HOLD button Freezes reading on the display to allow recording of measurement
  •  BEPS (Battery Error Prevention System) Meter will automatically shut off if there is not enough power to get an accurate measurement
  • Battery % level at startup
  • Low Battery Indicator When the level is below 5%, the  battery symbol on the LCD blinks to indicate a low battery condition.
  •  Auto-off  feature automatically shuts off  meter after 8 minutes of non-use to maximize battery life
