    6.2. COLLECTING AND MEASURING SAMPLES AND REAGENTS 6.2.1. PROPER USE OF SYRINGE (a) Push the plunger completely into the syringe and insert the tip into the solution. (b) Pull the plunger up until the lower edge of the seal is exactly on the mark for the desired volume.

  • Page 20: Cuvette Preparation

    6.3. CUVETTE PREPARATION Proper mixing is very important for reproducibility of the measurements. The proper mixing technique for each method is listed in the method procedure. (a) Invert the cuvette a couple of times or for a specified time: hold the cuvette in the vertical position.

  • Page 21: Timers And Measurement Functions

    Do not let the reacted sample stand too long after reagent is added. For best accuracy, respect the timings described in each specific method. It is possible to take multiple readings in a row, but it is recommended to take a new zero reading for each sample and to use the same cuvette for zeroing and measurement when possible.

    ® Standards. For accurate validation results, please perform tests at room temperature (18 to 25 °C; 64.5 to 77.0 °F). Validation of the HI83300 involves absorbance measurements of certified HANNA CAL Check ® Standards (see “Accessories”). The “CAL Check” screen guides the user through the measurement of each CAL Check Standard and applies the factory calibration corrections to each measurement.

  • Page 25 Preparation Pour small quantities of the buffer solutions into clean beakers. If possible, use plastic beakers to minimize any EMC interferences. For accurate calibration and to minimize cross‑contamination, use two beakers for each buffer solution: one for rinsing the electrode and one for calibration. If you are measuring in the acidic range, use pH 7.01 or 6.86 as the first buffer and pH 4.01 as the second buffer.

  • Page 26: Ph Calibration Messages

    Wrong Temperature: The buffer temperature is too extreme for the selected buffer value. 7.3. pH MEASUREMENT HI83300 can be used to perform direct pH measurements by connecting a HANNA digital ® pH electrode with a 3.5 mm TRRS connector. To begin taking probe measurements, connect the electrode to the 3.5 mm port marked with EXT PROBE located at the rear of the meter.
  • Page 27 Press to switch to Photometer mode. Press to access the meter’s Setup menu. Press to log the current measurement. Press to review the meter’s log history. Press to view contextual help information.
