Hanna 3 in 1 Combo Tester (pH, Conductivity, and TDS) Meter HI98129, Hanna Instruments, Romania \n \nThe HI98129 and HI98130 are waterproof testers that offer high-accuracy pH, EC/TDS, and temperature measurements in a single tester; no more switching between meters for your routine measurements. These floating, waterproof combination testers have an easy-to-read LCD and an automatic shut-off. pH and EC/TDS readings are automatically temperature-compensated. \n \nThese testers feature a replaceable pH electrode cartridge with an extendable cloth junction, as well as an EC/TDS graphite electrode. The renewable cloth junction provides an extended electrode life and the replaceable pH cartridge means that this tester does not need to be thrown away when the pH sensor is exhausted. \n \nThe EC/TDS conversion factor is user-selectable, as well as the temperature compensation coefficient (β). Fast, efficient, accurate, and portable, the Combo pH, EC/TDS, and temperature testers combine all the features users have requested and more! \n

Feature of 3 in 1 Combo Tester HI-98129

\n

\n
• Waterproof 3 in 1 Hanna Meter
\n
• Designed to float if accidentally dropped in a tank
