Combo pH/EC/TDS/Temp Meter
The new waterproof 50-HI98129 & 50-HI98130
Combo testers from Hanna are designed for 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. At startup, Combo performs a self check then
displays the remaining battery level to assure proper working condition. These
testers also have a stability indicator and hold feature to prompt the user when
to take the reading & freeze the display for easy and accurate recording.
Calibration and temperature compensation is automatic, while the EC / TDS
conversion factor and temperature coefficient factor (ß) are user adjustable
for application specific measurements. For calibration in pH, the user may
choose between standard or N.I.S.T. buffer sets.
The combo has a replaceable pH electrode
cartridge with an extendable cloth junction as well as an EC/TDS graphite
electrode which resists contamination by salts and other substances that come in
contact with the electrode. These new pH / EC / TDS / Temperature meters have a
stainless steel temperature probe for faster and more precise temperature
measurement. Fast, efficient, accurate and portable, the Combo pH, EC/TDS and
temperature tester meets the requirements of your routine multi-measurements.
Choose your Combo according to the proper
EC / TDS ranges for your application:
- 50-HI98129; EC - 0 to 3999 µS/cm;
TDS - 0 to 2000 ppm
- 50-HI98130; EC - 0.00 to 20.00
mS/cm; TDS - 0.00 to 10.00 ppt
Combo is supplied complete with 50-HI73127
pH electrode, 4 x 1.5V batteries and electrode
replacement tool (50-HI73128).
