  • Page 3: Preliminary Examination

    GENERAL DESCRIPTION HI9224 and HI92240 respectively, are the first printing and printing/ logging microprocessor-based portable pH/°C meters in the world. All pH measurements are automatically compensated for temperature (ATC). The instruments' housing is made of rugged, lightweight mate- rial, making it truly portable.

  • Page 8: Operational Guide

    OPERATIONAL GUIDE SET DATE / TIME / PRINTING INTERVAL (FOR HI92240 ONLY): Press the ALT and the TIME keys simultaneously. The display will show the date setting. At the bottom of the display the year will be flashing. DATE RANGE TIME Use the UP or the DOWN arrow key to select the year.
  • Page 9 Use the UP or the DOWN arrow key to select the correct day. Press the ALT and the TIME keys simultaneously. RANGE TIME The display will now show the clock time with the printing interval flashing. TIME INTV Any interval can be selected from 1, 2, 5, 10, 15, 30, 60, 120 or 180 minutes by using the UP and the DOWN arrow keys.
  • Page 10 The right hand side of the display showing the minutes will flash. TIME INTV Use the UP or the DOWN key to select the minute. Press the ALT and the TIME keys simultaneously to leave this mode. RANGE TIME Your clock, date and printing interval are now set and stored in memory even when the display is switched off.
  • Page 11 Note: the pH value will be displayed without any symbol. The temperature value will be displayed together with the °C symbol. TO VIEW PH / TEMPERATURE (WITH HI9224 ONLY) When the instrument is turned on the display will be in pH measurement mode. To view temperature simply press the RANGE key.

  • Page 12: Taking Ph Measurements

    TAKING PH MEASUREMENTS To take pH measurements, simply submerge the bottom 4 cm (1½") of the electrode and the temperature probe in the reading solution to be tested, stir gently and allow for the electrode to 4 cm (1½") adjust and stabilize. For greatest accuracy, it is recommended to calibrate the meter regularly (see page 13).

  • Page 13: Ph Calibration Procedure

    pH CALIBRATION PROCEDURE For greatest accuracy, it is recommended that the instrument is calibrated frequently. For a faster procedure, it is possible to calibrate at 1 point (pH 7.01), but it is always a good practice to calibrate at 2 points. Due to electrode conditioning time the electrode must be kept immersed a few seconds to stabilize.
  • Page 14 5. “4” can be changed to “10” (indicating pH 10.01) by pressing BUFF button. If you are measuring acid samples (pH 7 or less) use BUFF the pH 4.01 buffer (HI7004). For alkaline solutions (pH 7 or greater) use pH 10.01 (HI7010).
  • Page 15 3. When the “7” stops blinking, the calibration can be confirmed. Wait 30 seconds and press the CON key to confirm the first buffer. If wrong solution or electrode has been used or if the buffer is out of specifications the “7” symbol will not stop blinking to alert the user.
  • Page 16 CALIBRATION PRINTOUT (FOR HI92240 ONLY) During calibration, the characteristics of the electrode will be printed to record the electrode's performance over time. After the first point calibration a first set of data will be printed. This will consist of: 10-01-96 *02.13 date, time, the temperature compensated pH 7.04...

  • Page 18 Note: If the PRINT key is pressed while still in recording mode, a printout is produced without affecting the running number. PRINT TO STOP RECORDING In order to quit the recording mode, press the ON/OFF key. The running log number can be reset by simply removing the batteries.

  • Page 19: Printing / Logging With Hi 92240

    PRINTING / LOGGING WITH HI 92240 To print the measured values shown on display, press the PRINT key. This function can be acti- vated in normal operational mode as well as PRINT during logging and scanning data on display (see below).
  • Page 20 To log without printing press the ALT and the PAPER keys at the same time and the "LOG" symbol on display will start to blink. Press ALT and PAPER again to resume logging with printing. PRINT PAPER After approximately 5 minutes the display will switch off but the logging function remains active.

  • Page 26: Fault Functions

    FAULT FUNCTIONS HI 9224 and HI 92240 are factory programmed to automatically diagnose a fault. This is displayed with error codes on the LCD. Error codes: PEr0, PEr1, PEr2 = Short circuit on the system, the meter should be returned for repair (see Warranty section). PEr3 = Printer mechanism fault - repair needed (see Warranty section).

  • Page 33: Temperature-Resistance Correlation For Hanna Ph Sensitive Glass

    TEMPERATURE-RESISTANCE CORRELATION FOR HANNA PH SENSITIVE GLASS The resistance of glass electrodes partially depends on the tempera- ture. The lower the temperature, the higher the resistance. It takes longer time for the reading to stabilize if the resistance is higher. In addition, the response time will suffer to a greater degree at temperatures below 10°C.
  • Page 34 High concentrations of sodium ions interfere with readings in alkaline solutions; the pH at which the interference starts to be significant depends upon the composition of the glass. This interference is the alkaline error and causes the pH to be underestimated. Hanna's glass formulations have the indicated characteristics.
