The waterproof HI 98129 pH / EC / TDS / Temp Waterproof Tester from
Hanna is designed for high accuracy pH, EC/TDS and temperature measurements.
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.
The HI 98129 is supplied complete with an HI 73127 pH electrode, 4 x 1.5V batteries and electrode replacement tool (HI 73128).

NOTE: BGH highly recommends the use of Electrode
Cleaning and Electrode Storage Solution with any meter. Customers have sent
their defective meters back only to have them returned because there was nothing
wrong with them - all they needed was a good cleaning. By using Electrode Storage
Solution you will lengthen the life of the electrode (which is warranteed for
only six months) and minimize the frequency in which you will have to clean
it.
