The HI98129
Combo tester from Hanna Instruments is designed
for fast, efficient and high accuracy pH, EC/TDS and temperature measurements.
No more switching meters to measure the pH and then the EC or TDS of a solution.
This tester has a hold feature to prompt the user when to take the reading & a
display freeze for easy and accurate recording. Calibration and temperature
compensation is automatic. The combo has a replaceable pH electrode cartridge
and an EC/TDS graphite electrode which resists contamination. The temperature
probe is stainless steel, for faster and more precise measurement. The Combo
is supplied complete with HI 73127 pH electrode, 4 x 1.5V batteries and
electrode replacement tool (HI 73128).

Do you need to monitor a higher range of EC/TDS?
Consider the HI98130! It measures up to
20.00 mS/cm (20,000 µS/cm) or
10 ppt (10,000 ppm).
