Page 3: General Introduction
TDS simultaneously with user prompts and mode indicators. The unit prompts the user through calibrations and measurement procedures. The Model H10C is available with a single four wire conductivity cell that measures from 2 µS to 200 mS. Its features include automatic conductivity ranging, automatic temperature compensation, long battery life and 50/60 Hz AC noise rejection. -
Page 4: Installing The Batteries
Installing the Batteries The Model H10C meter is packaged with 4 “AAA” alkaline batteries required for operation. To insert the batteries into the meter, follow the procedure outlined below. Use a screw driver to remove the two screw and battery cover to expose the battery compartment. -

BAT- ℃: Indicates temperature reference unit. Low Battery Indicator %: Indicates temperature coefficient unit. 3. UNCOMPENSATED- 10. ppt- Distinguishes between temperature... -
Page 6: Keys
Keys On/Off- Powers on and shuts off the meter. Mode- Selects display mode. In normal operation, press Mode to sequentially display compensated conductivity, salinity, total dissolved solids (TDS) and uncompensated conductivity. In calibration mode, this key exits the current calibration and displays the next calibration parameter. Up/Down- Increases or decreases the displayed value as desired Cal-... -
Page 7: Operational Procedures
Here are some standard solutions the user can prepare to calibrate the probe of the model H10C. Standard solution of 1413uS at 77°F (25°C): Accurately weight out 0.746 grams of research grade dried Potassium Chloride (KCL). Dissolve in 1000ml of distilled water. -
Page 8: Cell
b. CELL The second screen will display CELL and the current cell value. The default cell value is 0.50 and is displayed in the lower right of the screen. The unit allows a variance of +/- 0.15 before displaying an error message. The cell value can’t be adjusted at this screen; calibrating conductivity is the only way to adjust the cell constant. -
