Page 3: Preliminary Examination
Universal Process Controller. The probes are recommended for a wide range of water applications, from pure and ultrapure water (two-ring series i.e. HI7630-28) to industrial process water (four-ring series i.e. HI7630-48 The two-ring probes can be calibrated using a standard with a value close to the measurement value whereas the four-ring probes provide stable measurements over a wide measure range and do not require frequent calibrations. -
Page 4: Main Features
Main Features TDS is a calculated value based on the conductivity of the solution (TDS = factor x EC ). A TDS factor is a conversion factor used to change an EC measurement to a ppm measurement. Sal psu: The practical salinity of seawater relates the ratio of electrical conductivity of a normal seawater sample at 15 ºC and 1 atmosphere to a potassium chloride solution (KCl) with a mass of 32.4356 g/Kg water at the same temperature and pressure. -

Page 8: Installation
Installation 8. INSTALLATION General considerations • Probes are easily installed using the 3/4” NPT external thread. • Hand tighten the probe in position. Then, depending on the process, tighten one or two turns with a wrench to secure in place. Do not exceed 10 N m (7.3 lb-ft) torque specification for the probe sensor. - Page 9 Installation Installation tee • Install the probe in a tee, horizontally, and direct the flow into the opening at the bottom of the probe. • Upward flow direction must always be ensured. • Maintain a stable flow rate to minimize interferences from bubbles and settling of particulates. •...
- Page 10 Installation To install the probe: A. Unscrew the protective end cap (9). The cap allows for quick and simple probe maintenance and replacement. B. Slide out the electrode holder cap (3). C. Screw the probe into the internally threaded protective cap (9), step I. D.

Wiring the Probe to the Controller 9. WIRING THE PROBE TO THE CONTROLLER 1. With the controller disconnected from power, run the probe cable through the conduit opening. 2. Connect the probe leads to the removable terminal connector marked PROBE. Follow the lead markings (+) positive / (–) negative to ensure correct wiring position for the output leads. -
Page 12: Calibration
Calibration 10. CALIBRATION HI510 controller allows two types of EC calibration procedures: • Standard two-point conductivity calibration with standards for cell factor determination: 0.000 µS/cm for offset 84.0 µS/cm, 1413 µS/cm, 5.00 mS/cm,12.88 mS/cm for the 0.1/cm cell 80.0 mS/cm, 111.8 mS/cm additional standards for the 1.0/cm cell •... - Page 13 25 °C. The self-ionization of water is highly temperature dependent. • Recommended temperature compensation setting for these type of measurements (taken with HI7630-28 probes only) is "Standard" as it utilizes the correct compensation algorithm. Calibration recommendations • Remove the probe from the process and shake all the water from the probe.
