List Price From $187.00

The Hanna Combo pH EC TDS Tester is a waterproof tester that offers high accuracy pH, EC/TDS and temperature measurements in a single tester. There is no need to switch between meters for routine measurements. This floating, waterproof combination tester has an easy to read LCD and an automatic shut-off. pH and EC/TDS readings are automatically temperature compensated.

This tester features a replaceable pH electrode cartridge with an extendable cloth junction as well as anEC/TDS graphite electrode. The extendable cloth junction provides an extended electrode life and the replaceable pH cartridge means this tester does not need 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 (β). This fast, efficient, accurate and portable combo pH, EC/TDS and temperature tester combines all the features users have requested.
