Remember to purchase the Conductivity Standard to calibrate. We recommend 1,413µS for this instrument, link at the bottom.
Remember to purchase the pH standard solutions to calibrate this instrument. We recommend you choose both the 4.01 and the 7.01 solutions.
Temperature in °C and °F
Rugged, Floating Waterproof Casing
Replaceable pH Electrode Featuring an Extendable Junction
The HI 98129 Combo waterproof 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 the 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 well as 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!
