FUNCTIONAL DESCRIPTION HI 931100 GENERAL DESCRIPTION Hanna Instruments microprocessor-based Sodium (HI 931101) / Sodium Chloride (HI 931100/HI 931102) analysers, are housed in rugged, lightweight material designed for single-handed use. To assure trouble-free operations, the meters' circuitry has a built-in protection against electromagnetic interference. All meters come equipped with a large and easy-to-read LCD, which shows sodium/sodium chloride and temperature values simultaneously and guides the user through the calibration procedure with easy-to-follow graphic symbols. In addition, HI 931101 and HI 931102 provide pNa or % NaCl readings respectively through the MODE key. Automatic calibration, rundown batteries indicator and water-resistant housing are the features which make these meters easy to use and versatile both in the laboratory and in the field applications. 3 1. 2. 3. 4. 5. 6. 7. 8.

In order to take accurate measurements, make sure the instrument is calibrated HI before use (see page 12 for HI 931101 and HI HI page 16 for HI 931100 & HI 931102). For greatest accuracy, calibration should be performed (or at least verified) every day for measurements taken in the same type of samples (e.g. cheese) or every time the sample type is changed (e.g. cheese, meat, sea water, etc.). The best working temperature is around 2025°C (68-77°F). For greater accuracy, perform the calibration of the meter with standard solution at a temperature as close as possible to the temperature of the sample (± 1°C/±2°F). Wait for up to 10 to 15 minutes to allow for the electrode to adjust and stabilize, i.e. until there is no drifting for at least a couple of minutes. During measurement, if possible, the sample should be gently stirred (100 rpm). MAGNETIC STIRRER HI 190M POWER ON OFF MAX SPEED pNa (for HI931101) and NaCl% (for HI931102) measurements Press the MODE key during measurement to convert the displayed value of HI 931101 to pNa. pNa = -log aNa where aNa is the activity of ion Na. TAKING SODIUM MEASUREMENTS Remove the protective cap of the FC 300B sodium-sensitive electrode and, if possible, rinse it with some of the sample you are going to measure. Lower the rubber sleeve to get the junction to work properly. Immerse the tip of the FC 300B electrode (2.5 cm/ 1" i.e. the electrode junction must be completely immersed) into the sample to be tested without touching the bottom of the beaker. 11 °C MODE Press the MODE key during measurement to convert the displayed value of HI 931102 to %. MODE Press the same key to return to g/L measurements. 12 mannacl_r1.P65 13 14 TAKING TEMPERATURE MEASUREMENTS To take temperature measurements, connect the temperature probe, turn the instrument on and dip the liquid/general purpose temperature probe HI 7662 into the sample. Allow the reading to stabilize. Note: the temperature is always displayed on the secondary display. gm Na CALIBRATION (HI 931101) The calibration is performed by immersing the FC 300B sodium-sensitive electrode in 2 different standard Na solutions to achieve accurate 2 point calibration. It is also possible to calibrate just the offset (2.3 g/L Na) following the single point calibration procedure described below. NaCl °C For best accuracy, a two-point calibration is recommended (see below). PREPARATION AFTER USE Turn the meter off by pressing the ON/OFF key again. For a faster and accurate measure, the electrode should be stored in a solution with a Na/ NaCl concentration similar to the sample to be measured. Upper the rubber sleeve after use. For infrequent use (once a month or less) store the electrode dry. Before using it again, let it condition overnight in HI7081/HI8081 (30.0 g/L NaCl) or HI7086/HI8086 (23 g/L Na 1M) To avoid very long response time, do not store or rinse the electrode with deionized water. Never rub or blot the electrode. 13 ON/OFF · Pour small quantities of HI7080 or HI8080 (2.3 g/L Na) solution and HI7087 or HI8087 (0.23 g/L Na) or HI7086 or HI8086 (23 g/L Na) into two clean beakers. 80 70 HI HI 7080 HI 7087 ON/OFF To obtain accurate readings, use HI7080/ HI8080 and HI7087/HI8087 if you are going to measure samples with low sodium content (below 2.3 g/L) or HI7080/HI8080 and HI7086/HI8086 if you are going to measure samples with high sodium content (over 2.3 g/L). · For accurate calibraRINSE CALIBRATION tion use two beaHI 7080 HI 7080 kers for each buffer calibration, the first one for rinsing the electrode, the second one for calibration. This way, contamination of the buffer is minimized. Whenever possible use plastic beakers to minimize any EMC interferences. · Turn the meter on by pressing the ON/OFF key. ON/OFF 14 mannacl_r1.P65 15 16 · Remove the protective cap of the electrode and rinse it with some of the buffer calibration solution you are going to use first. · Lower the rubber sleeve to get the junction to work properly For best results, wait for a couple of minutes before pressing the CFM key. · HI 931101 will display "0.230 gm". · If the CAL key is pressed at this point, the calibration process is ended providing only one point calibration. For better accuracy however, it is recommended that a two-point calibration is performed. CAL BUF CFM gm °C SINGLE POINT CALIBRATION (OFFSET) · Dip the FC 300B sodium electrode into the 2.3 g/L Na solution (HI 7080 or HI 8080). Note: the electrode should be immersed approximately 2.5 cm (1") into the solution. · Press the CAL key. The "CAL" and "BUF" indicators will be displayed with the "BUF" and the " " symbols blinking. 2.3 g/L Na CAL TWO POINT CALIBRATION · Proceed as described in "Single Point Calibration" but do not quit calibration by pressing the CAL key. · After the first point is confirmed, immerse the FC 300B electrode into the second buffer solution at 0.23 g/L Na (HI7087/ HI 8087) or 23 g/L Na 0.23 g/L or 23 g/L (HI 7086/HI8086).
