Hanna HI 98129 pH/Conductivity/TDS Tester
The HI 98129 is a waterproof tester that offers high accuracy pH, EC, TDS and Temperature measurements in a single tester. No more switching between meters for your routine measurements. These floating, waterproof testers have a large easy to read dual level LCD and automatic shut off. pH, EC and TDS readings are automatically temperature compensated.
Your tester no longer needs to be thrown away when the ph sensor is exhausted. This technologically advanced tester has a replaceable 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 an extended life.
The EC/TDS conversion factor is user selectable, as is the temperature compensation coefficient.
