Choose HI 98129 or HI 98130 according to the proper EC/TDS ranges for your application


HI 98129; EC - 0 to 3999 µS/cm; TDS - 0 to 2000 ppm


HI 98130; EC - 0.00 to 20.00 mS/cm; TDS - 0.00 to 10.00 ppt


  • Temperature in °C and °F
  • Rugged, Floating Waterproof Casing
  • Replaceable pH Electrode Featuring an Extendable Junction


The HI 98130 Combo waterproof tester offers high accuracy pH, EC/TDS and temperature measurements in a single tester! No more switching between meters for your routine measurements. The waterproof Combo (it even floats) has a large easy-to- read, dual-level LCD and automatic shut off. pH and EC/TDS readings are automatically compensated for the effects of temperature (ATC).


This technologically advanced tester has a replaceable pH electrode cartridge with an extendable cloth junction as well as an EC/TDS graphite electrode that resists contamination by salts and other substances. This gives the meter a greatly extended life. Your tester no longer needs 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 (ß). Fast, efficient, accurate and portable, the Combo pH, EC/TDS and temperature tester brings you all the features you've asked for and more


HI 98129 is supplied complete with protective cap, electrode removal tool, batteries and instructions.
