Versatile combination pH tester

September 2001 Sensors & Transducers

The new robust Combo waterproof testers from Hanna Instruments measure pH, EC, TDS and temperature all in one tester. No more switching between instruments. All pH and EC/TDS measurements are automatically temperature compensated. The EC/TDS conversion factor and the temperature compensation coefficient are user-selectable. The Combo is waterproof and floats and has a large, easy-to-read dual-level LCD. Automatic calibration and a stability indicator for pH are included. A remaining battery life % indication tells the user how much battery life is left. The replaceable pH electrode has a cloth junction which can be pulled out to rejuvenate the electrode. The graphite EC probe provides greater accuracy and stability as it resists contamination by salts and other substances.

Both models with a pH range of 0-14,00 and temperature from 0-60°C and EC range from 0-3999 µS/cm and 0-20,00 mS/cm and 0-10,00 ppt for III 98130; these testers are suitable for many applications.
