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!
