    WARRANTY HI 2300 is guaranteed for two years against defects in workmanship and materials when used for its intended purpose and maintained according to instructions. Electrodes and probes are guaranteed for six months. This warranty is limited to repair or replacement free of charge.

  • Page 3: Preliminary Examination

    All defective items must be returned in the original packing with the supplied accessories. GENERAL DESCRIPTION The HI 2300 is a logging microprocessor-based Conductivity (EC), TDS, NaCl and Temperature bench meter. The conductivity measurements are compensated for temperature effect manually or automatically with the temperature sensor inside the conductivity probe.

  • Page 7: Operational Guide

    OPERATIONAL GUIDE POWER CONNECTION Plug the 12 VDC adapter into the power supply socket. Notes: • This instrument uses non volatile memory to retain the calibration parameters and all other settings, even when unplugged. • Make sure a fuse protects the main line. PROBE CONNECTION For EC/TDS or temperature measurements connect the probe to the 7-pin connector.
  • Page 8 The conductivity reading is affected by temperature. Three options for temperature compensation are available in conductivity measurement mode. Note: The compensation is referenced at the selected reference temperature (see SETUP for details, page 21). To select the desired option, press the ALT&ATC keys until the option is displayed on the LCD.

  • Page 9: Auto-Ranging

    • If the reading is out of range, the full-scale value (100.0 for Mtc/Atc mode or 400.0 for uncompensated TDS) will be displayed blinking. • If LOCK was pressed to freeze the LCD range and the reading goes out of range, the full-scale value of the frozen range will be displayed blinking.

  • Page 10: Ecs/Tds Calibration

    EC/TDS CALIBRATION Selectable calibration points for conductivity are 0.00 µS for offset and 84.0 µS, 1413 µS, 5.00 mS, 12.88 mS, 80.0 mS, 111.8 mS for slope. Rinse the probe with calibration solution or deionized water. Submerse the probe into the solution. The sleeve holes must be completely submersed.
  • Page 11 Notes: • If the reading is too far from the expected value, the “WRONG” and “ ” tags will blink. Calibration can not be confirmed. In this case check if the calibration solution has been used correctly or clean the probe by following the Probe Maintenance (see page 31).

  • Page 12: Conductivity Versus Temperature Chart

    CONDUCTIVITY VERSUS TEMPERATURE CHART The conductivity of an aqueous solution is a measure of its ability to carry an electrical current by means of ionic motion. The conductivity invariably increases with increasing temperature. It is affected by the type and number of ions in the solutions and by the viscosity of the solution itself.

  • Page 13: Nacl Calibration

    NaCl CALIBRATION NaCl calibration is a one-point calibration at 100.0% NaCl. Use the HI 7037L calibration solution (sea water solution) as a 100% NaCl calibration solution. Rinse the probe with some of the calibration solution or deionized water. Submerse the probe into HI 7037L solution.

  • Page 14: Good Laboratory Practice (Glp)

    GOOD LABORATORY PRACTICE (GLP) GLP is a set of functions that allows storage and retrieval of data regarding the maintenance and status of the system. All data regarding EC and NaCl calibration is stored for the user to review when necessary. EC CALIBRATION DATA EC calibration data is stored automatically after a successful calibration.
  • Page 15 • The temperature coefficient. • The instrument ID. NaCl CALIBRATION DATA NaCl calibration data is stored automatically after a successful calibration. To view the NaCl calibration data, press GLP when the instrument is in NaCl measurement mode. The instrument will display the time (hh:mm) of the last calibration. Use the ARROW key to scroll through the calibration data.

  • Page 16: Logging Function

    Notes: • If no temperature compensation is selected during calibration, the temperature coefficient is not displayed in GLP. • Press GLP at any moment and the instrument will return to measurement mode. • If calibration has not been performed on the selected range, the instrument displays “no CAL”...
  • Page 17 If the log space is full (500 records), “FULL LOG” message will be displayed and no more data will be saved. When LOG is pressed, a complete set of information is stored: date, time, EC, TDS, NaCl, temperature and calibration data. VIEW LOGGED DATA Press the ALT&RCL keys while in measurement mode to retrieve the stored information.

  • Page 25: Temperature Calibration (For Technical Personnel Only)

    TEMPERATURE CALIBRATION (for technical personnel only) All the instruments are factory calibrated for temperature. Hanna’s temperature probes are interchangeable and no temperature calibration is needed when they are replaced. If the temperature measurements are inaccurate, temperature recalibration should be performed. For an accurate recalibration, contact your dealer or the nearest Hanna Customer Service Center, or follow the instructions below.
  • Page 26 • Use the ARROW keys to set the reading on the secondary LCD to that of the hot water. • When the reading is stable and close to the selected calibration point, the “CFM” tag will blink. • Press CFM to confirm. The instrument memorize calibration and restart in measurement mode.
