Product Description
HI981304 Pool Line Combo pH/EC/TDS meter is made for measuring pH and EC or TDS of swimming pool, hot tub, or spa water. This lightweight, waterproof tester offers high accuracy pH, high range EC/TDS (0.00 to 20.00 mS/cm EC/ 0.00 to 10.00 ppt TDS) and temperature measurements in a single handheld unit.
Waterproof and designed to float in water
Replaceable pH electrode with 0.01 pH resolution
Selectable EC/TDS conversion factor
Features at-a-glance
Amperometric EC/TDS sensor, pH electrode, and temperature probe in one meter
High accuracy EC/TDS graphite probe reduces polarization effects and does not oxidize
Selectable EC to TDS conversion factor of 0.45 or 1.0
Automatic Temperature Compensation coefficient ? (BETA), displays temperature in °C or °F
Large LCD displays stability indicator, low-battery indicator, and calibration tags
HOLD button for easier measurement recording
Battery Error Prevention System (BEPS) with low battery indicator
