HI 98129 is a waterproof tester that offers high accuracy pH, EC/TDS(PPM) and temperature measurements in a single tester! No more switching between meters for your routine measurements. This floating, waterproof combination tester has an easy to read, LCD and an automatic shut-off. pH and EC/TDS(PPM) readings are automatically temperature compensated.

This tester features a replaceable pH electrode cartridge with an extendable cloth junction as well as an EC/TDS(PPM) graphite electrode. The extendable 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(PPM) conversion factor is user selectable as well as the temperature compensation coefficient (β).
Fast, efficient, accurate and portable, the Combo pH, EC/TDS(PPM) and temperature tester combines all the features users have requested and more!
