HI98130 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. This floating, waterproof combination tester features an easy to read, LCD and an automatic shut-off. pH and EC/TDS readings are automatically temperature-compensated.
These testers feature a replaceable pH electrode cartridge with an extendable cloth junction, as well as an EC/TDS graphite electrode. The extendable 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.
The 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 tester combines all the features users have requested and more!
- Waterproof and designed to float
- Automatic Temperature Compensation
- HOLD button to freeze readings on the display
- BEPS Alerts the user of low battery power that could adversely affect readings
