The HI 98129 Combo waterproof tester offer 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 these meters 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 is 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!
