The HI98130 is a highly accurate, waterproof combo ph ec tester that can also measure EC/TDS in the high range (0.00 to 20.00 mS/cm EC/ 0.00 to 10.00 ppt 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 (ATC) to prevent temperature-related variations in your measurements. For EC/TDS readings, the EC/TDS conversion factor (CONV) is selectable by the user, as well as the temperature compensation coefficient β (BETA).
Replaceable pH Electrode Cartridge
The HI98130 pH and conductivity 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.
