HANNA HI 98129 MEASURE PH/EC/TDS/TEMPERATURE WITH ONLY ONE TESTER
The HI 98129 Combo waterproof tester offer high accuracy pH, EC/TDS and temperature measurements all in a single tester!
No more switching between meters for your routine measurements. The waterproof Combo (it even floats) has a large easyto- 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 well as the temperature compensation coefficient (â). Fast, efficient, accurate and portable, the Combo pH, EC/TDS and temperature tester brings you all the features you've asked for and more!
