HI981304 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 has an easy-to-read LCD and automatic shut-off. pH and EC/TDS readings are automatically temperature- compensated. The EC/TDS conversion factor is user- selectable, as well as the temperature compensation coefficient (β).
High accuracy EC/TDS graphite probe The graphite conductivity probe provides greater accuracy because it cannot be contaminated by salt deposits. The exposed temperature sensor provides fast response times and guarantees highly accurate temperature compensated readings.
Replaceable pH electrode cartridge The Combo features an easy-to-replace pH electrode. The sturdy, snap-in connector means there are no pins which could bend or break.
Protective cap The protective cap features an internal cup that can be filled with storage solution to keep the pH sensor moist.
