    OPERATION The BE500 pH meter is powered by a built-in 4.2V lithium battery. Keypad Operation There are six buttons on the BE500 panel (see below Figure). Their functions are described in table 1. Table 1 Keypad Operation and Functions Keypad...
  • Page 6 Momentarily press the button to enter MENU mode. There are six menu Short Press items by pressing the button shortly to loop. The menu items are described in the table x. In the MEASUREMENT mode the user presses it to manually log one pH reading onto the meter memory.
  • Page 7 LCD backlight will turn off automatically after 60 seconds of button inactivity. Changing the Operation Mode BE500 pH meter has four operation modes: MEASUREMENT, MENU, DATA and FREEZE mode (see table 2). Change the operation mode from four available modes depending on the purpose of use. The status icon indicates the current mode.
  • Page 8 Users can change the operation mode using the corresponding key. However changing to the MENU mode, DATA mode, or FREEZE mode is possible only from the MEASUREMENT mode. When changing to a different mode, first change to the MEASUREMENT mode and then change to the desired mode.

  • Page 10: Operating Hints

    Operating Hints This section gives some brief operating hints and good laboratory practices to help assure trouble free pH measurements. 1. If you are measuring hot or cold samples without the use of an ATC probe, the values displayed are not accurate. You should be calibrating and measuring at room temperature.
  • Page 11 Put the electrode measuring end down, hold the electrode and shake it for several times to make the electrode bulb full of solution without bubbles. Keep the electrode filling port open, connect the electrode plug with the pH meter. When connecting the electrode into the meter, please slowly rotate the connector, identify the location of the mount to insert it, and then screw it on.
  • Page 12 PH CALIBRATION The BE500 pH meter allows 1 to 3 points calibration. We recommend that you perform at least 2 points calibration for high accuracy measurement. The meter adopts two series of standard buffer solutions: USA and NIST as shown in Table 4.

  • Page 14 To eliminate temperature errors associated with the pH electrode, attach the Automatic Temperature Compensation (ATC) probe for best accuracy. Without temperature compensation, pH accuracy will worsen as samples deviate from 25 ºC and pH 7.00. The 1st point must be 7.00 pH (or 6.86 if using NIST). Then choose other calibration solutions to conduct 2nd and 3rd points.
  • Page 15 Press the button third times to select the item "PH Calibration 2 4.01 pH" (or "PH Calibration 2 4.01 pH" if using NIST) in MENU mode. Press button to calibrate the meter (2nd point). The device automatically save the calibration data and returns to the MEASUREMENT mode after it finishes the process.

    solutions for measurements that are expected to be on the lower side of the scale : Perform Step 1 and Step 2. 2) Use the 7.00 pH and 10.00 pH (or 6.86 pH and 9.18 pH if using NIST) solutions for measurements that are expected to be on the higher side of the pH scale : Perform Step 1 and Step 3.
  • Page 17 PH MEASUREMENT To measure the sample pH, rinse the pH electrode in distilled water, dry it, and dip it into sample solution. Immerse at least 3 cm from the tip of the pH electrode in the sample solution. Swirl or stir the solution gently and let it stand still in the sample solution.

    compensation accordingly Press button to confirm the setting and return to the measurement screen. The default MTC temperature value setting is 25 °C (77°F). Note: °C = 5/9 (°F - 32) pH isothermal measurement principle According to the pH isothermal measurement principle, the closer the test sample's temperature is to the calibration solution's, the higher the accuracy of the measurement.

    258 grams (9.1 oz.) MAINTENANCE Cleaning and Storage The BE500 pH Meter needs no maintenance except for an occasional wipe with a damp cloth. It is good laboratory practice to wipe away any spills as soon as they occur. The front panel and case can be cleaned with a mild solution of detergent and water.
  • Page 20 to maintain the sensitivity of the glass bulb. Loosen the vial, remove the electrode and rinse in distilled water before taking a measurement. Insert the electrode and tighten the vial after measurements to prevent the reference solution from leaking. If the soaking solution is turbid or moldy, replace it with KCL solution.

    come in contact with hard surfaces. Scratches or cracks on the electrode will cause inaccurate readings. Before and after each measurement, the electrode should be rinsed with distilled water. If a sample sticks to the electrode or it's contaminated, the electrode should be thoroughly cleaned using a soft brush and then rinsed with distilled water.
