Force and mechanical measuring equipment
– Measure pH/Conductivity (EC)/Total Dissolved Solids (TDS) Simultaneously.
*Conductivity mS/cm and TDS in g/L.
– Compact, pocket-friendly design.
– The pH electrode is removable and replaceable.
– Automatic temperature compensation.
– Provide a complete set including meter, electrode and standard solution, washing and storing electrodes.
REMOVABLE pH ELECTRODES
The HI981304 waterproof, highly accurate pH meter measures EC/TDS with a cloth junction. The extended cloth junction extends electrode life and the pH electrode is replaceable. Additionally, the replacement electrode has no pins so it will not bend or break.
EC/TDS GRAPHIC DETECTOR
The conductive graphite probe provides higher accuracy because it is not contaminated by salts in the solution.
AUTOMATIC TEMPERATURE COMPENSATION
The machine integrates a temperature sensor for quick response time and ensures temperature compensation for highly accurate measurement results.
AUTOMATIC CALIBRATION
The machine has an automatic calibration function with supplied calibration solutions
– pH: Calibration at 2 points at pH 4.01 / 7.01 / 10.01
– EC/TDS: 1 point calibration at 12.88 mS/cm, 6.44 ppt (g/L)
Because EC and TDS are correlated, you only need to calibrate 1 EC or TDS point for both parameters
HOLD BUTTON
Helps keep a stable value on the screen to facilitate recording and storing measurement values
STABLE SYMBOL
The hourglass icon will flash during measurement and disappear to indicate that the measurement result has stabilized and this value has been taken.
SUPPLIED COMPLETE SET
The HI981304 is supplied complete with everything you need to perform measurements without the need for additional purchases:
– Meter and internal pH, EC and temperature electrodes
– pH4.01 and 7.01 calibration solution packets and EC and TDS
– Electrode cleaning solution after measurement
– Electrode preservation solution.
