Hanna Combo Tester (pH, Conductivity, and TDS) Meter HI98129, Hanna Instruments, Romania

The HI98129 and HI98130 are waterproof testers that offer high accuracy pH, EC/TDS and temperature measurements in a single tester; no more switching between meters for your routine measurements. These floating, waterproof combination testers have an easy-to-read LCD and an automatic shut-off. pH and EC/TDS readings are automatically temperature-compensated.

These testers feature a replaceable pH electrode cartridge with an extendable cloth junction, as well as an EC/TDS graphite electrode. The renewable cloth junction provides an extended electrode life and the replaceable pH cartridge means that this tester does not need to be thrown away when the pH sensor is exhausted.

The EC/TDS conversion factor is user selectable, as well as the temperature compensation coefficient (β). Fast, efficient, accurate and portable, the Combo pH, EC/TDS, and temperature testers combine all the features users have requested and more!

  • Designed to float if accidentally dropped in a tank
  • Automatic Temperature Compensation
    All readings are compensated
    for variations in temperature
  • Temperature displayed in °C or
    °F along with pH 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)

  • Battery % level at startup
  • Low Battery Indicator
  • Auto-off
  • Automatically shuts off after 8 minutes
    of non-use to maximize battery life
