Features & Applications:

This Hanna waterproof combo pH / EC / TDS / temperature tester offers 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 this meter 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! Performs a self check at startup, then displays battery level. Testers include automatic temperature and compensation, autocalibration, a stability indicator, and a "hold" feature to ensure proper measurement and to freeze the display for accurate recording. Comes complete with pH electrode, four 1.5V batteries and an electrode replacement tool.
