The HI98129 makes measuring pH quick and easy! This lightweight, waterproof tester offers high accuracy pH, EC/TDS and temperature measurements in a single handheld unit! No more switching between meters for your routine measurements.
Details
The HI98129 is a highly accurate, waterproof pH meter that can also measure EC/TDS and temperature. This floating, waterproof combination tester has an easy to read, LCD and an automatic shut-off. In addition, pH and EC/TDS readings are automatically temperature-compensated to prevent temperature related variations in your measurements.
The EC/TDS conversion factor is user selectable as well as the temperature compensation coefficient.
Replaceable pH Electrode Cartridge
The HI98129 tester features an easy to replace pH electrode cartridge with an extendable cloth junction. The extendable cloth junction helps increase electrode life and the replaceable pH cartridge means that this tester does not need to be thrown away when the pH sensor is exhausted. Also, the sturdy, snap-in connector means there are no pins to bend or break!
High Accuracy EC/TDS graphite probe
The graphite conductivity probe provides greater accuracy because it cannot be contaminated by salt deposits in the solution. The exposed temperature sensor provides fast response times and guarantees highly accurate temperature compensated readings.
Fast, efficient accurate and portable, the Combo pH, EC/TDS and temperature tester combines all the features users have requested and more!
