Testers

pH/Conductivity/TDS Waterproof Tester

Replaceable pH electrode cartridge

The Combo features an easy-to-replace pH electrode has an extendable cloth junction. Thesturdy, snap-in connector means there are no pins to bend or break.

High accuracy

The graphite conductivity electrode provides greater accuracy because it cannot be contam- inated by salt deposits in the solution. The exposed temperature sensor provides fast response times, and guarantees accurate temperature compensated readings. The HI 98129 and HI 98130 Combo waterproof testers offer high accuracy pH, EC/TDSand temperature measurements with a large easy-to-read, dual-level LCD and automat-ic shut-off. pH and EC/TDS readings are automatically compensated for the effects of temperature (ATC). The EC/TDS conversion factor is user selectable as well as the tem- perature compensation coefficient ( β ). Fast, efficient, accurate and portable, the Comboincorporates all the features asked for and more! SPECIFICATIONS Combo (HI 98129) Combo (HI 98130)
