Milwaukee Instruments MW100 pH Meter

Konec produktuview

The Milwaukee MW100 is a compact, portable pH meter designed for fast and reliable measurements. It features a fast microprocessor and a large, easy-to-read LED display. This meter is suitable for a wide range of applications including educational, agriculture, horticulture, and water analysis. It offers manual 2-point calibration for accurate results.

Obrázek 1: Přední strana view of the Milwaukee MW100 pH Meter. The display shows "pH 1.2". Below the display are "ON" and "OFF" buttons. Further down, there are two calibration knobs labeled "pH4/10" and "pH7" under a "Calibration" heading.

Obsah balení

Po vybalení ověřte, zda jsou všechny položky přítomny a nepoškozené:

• MW100 pH Meter unit
• pH elektroda MA911B/1
• pH 7.01 calibration solution sachet (20mL)
• Kalibrační šroubovák
• 9V alkalická baterie
• Návod k použití (tento dokument)

Nastavení

1. Instalace baterie

1. Vyhledejte přihrádku na baterie na zadní straně měřiče.
2. Otevřete kryt bateriového prostoru.
3. Insert the 9V alkaline battery, observing the correct polarity.
4. Bezpečně zavřete kryt bateriového prostoru.

2. Připojení elektrody

1. Remove the protective cap from the MA911B/1 pH electrode.
2. Connect the BNC connector of the pH electrode to the BNC socket on top of the MW100 meter. Ensure a firm connection.
3. Rinse the electrode tip with distilled water before first use.

Návod k obsluze

Turning the Meter On/Off

• To turn the meter ON, press the "ON" button located below the display.
• To turn the meter VYPNUTO, press the "OFF" button located below the display.

Měření pH

1. Ensure the meter is calibrated (see Calibration section).
2. Opláchněte pH elektrodu destilovanou vodou.
3. Ponořte hrot elektrody doamproztoku a ujistěte se, že je snímací žárovka zcela ponořená.
4. Stir gently and wait for the reading on the display to stabilize.
5. Zaznamenejte hodnotu pH.
6. After measurement, rinse the electrode with distilled water and replace the protective cap.

Manuální kompenzace teploty

The MW100 features manual temperature compensation from 0 to 50 degrees Celsius. To ensure accurate readings, measure the temperature of your sample solution separately and adjust the temperature compensation setting on the meter accordingly if available (Note: The MW100 description states manual temperature compensation but does not detail a user-adjustable knob for it. It implies the user should account for temperature effects on pH readings, often done via external charts or calculations for precise work).

2-Point Manual Calibration

Calibration is crucial for accurate pH measurements. The MW100 uses a 2-point manual calibration process.

1. Příprava: Ensure you have fresh pH 7.01 and pH 4.01 (or pH 10.01) calibration solutions. Use the provided pH 7.01 sachet.
2. First Point (pH 7.01):
   • Zapněte měřič.
   • Rinse the electrode with distilled water and immerse it into the pH 7.01 calibration solution.
   • Počkejte, až se hodnota stabilizuje.
   • Using the provided calibration screwdriver, adjust the "pH7" trimmer knob (located on the front panel) until the display reads "7.0".
3. Second Point (pH 4.01 or pH 10.01):
   • Opláchněte elektrodu destilovanou vodou.
   • Immerse the electrode into the pH 4.01 (for acidic range) or pH 10.01 (for alkaline range) calibration solution.
   • Počkejte, až se hodnota stabilizuje.
   • Using the calibration screwdriver, adjust the "pH4/10" trimmer knob until the display reads "4.0" or "10.0" respectively.
4. Your meter is now calibrated. Rinse the electrode with distilled water before taking measurements.

Údržba

Electrode Care and Storage

• Always rinse the electrode with distilled water before and after each measurement.
• Do not wipe the glass bulb; gently blot it dry with a lint-free tissue.
• For short-term storage (up to one week), keep the electrode tip immersed in electrode storage solution or pH 7.01 buffer solution. Never store in distilled or deionized water.
• For long-term storage, ensure the protective cap is filled with electrode storage solution and securely placed over the electrode tip.
• If the electrode becomes dry, soak it in electrode storage solution for at least 30 minutes before use.

Výměna baterie

When the display becomes dim or the meter shows erratic readings, it's time to replace the 9V battery. Follow the battery installation steps in the "Setup" section.
