Its robust, waterproof design ensures reliability in diverse environments.

2. الميزات الرئيسية

• Refillable pH electrode for extended service life.
• Analog bargraph display on LCD for trend indication.
• Waterproof construction to IP57 standard.
• Automatic 1, 2, or 3 point calibration with buffer solution recognition.
• Flat Surface Electrode capable of measuring pH in liquids, semi-solids, and solids.

3. محتويات العبوة

The Extech PH110 Waterproof ExStik pH Meter package includes:

• Extech PH110 pH Meter with refillable pH electrode
• 1.5mL bottle of KCI (Potassium Chloride) solution
• Two reference junctions
• Two electrode removal tools
• غطاء حماية
• Sampلو كوب
• Four 3V CR-2032 batteries (pre-installed or included separately)
• 48-inch (1.2m) neck strap

4. الإعداد

4.1 تركيب البطارية

1. Ensure the meter is off.
2. حدد مكان حجرة البطارية.
3. Insert four 3V CR-2032 Lithium Metal batteries, observing correct polarity.
4. أغلق حجرة البطارية بشكل آمن.

4.2 تحضير القطب الكهربائي

1. قم بإزالة الغطاء الواقي من القطب.
2. Rinse the electrode tip with distilled water.
3. If the electrode appears dry, soak it in electrode storage solution or pH 7 buffer for at least 30 minutes before first use.

5. التشغيل

5.1 المعايرة

Calibration is essential for accurate measurements. The PH110 supports 1, 2, or 3 point calibration and automatically recognizes buffer solutions.

1. قم بتشغيل العداد بالضغط على تشغيل/إيقاف زر.
2. Prepare fresh pH buffer solutions (e.g., pH 4, 7, and 10). These are sold separately.
3. اضغط مع الاستمرار على كال button until 'CAL' appears on the display.
4. Immerse the electrode into the first buffer solution (e.g., pH 7). The meter will automatically recognize the buffer and calibrate. Wait for the reading to stabilize.
5. For 2 or 3 point calibration, rinse the electrode with distilled water and immerse it into the next buffer solution (e.g., pH 4, then pH 10). The meter will continue to calibrate automatically.
6. Ensure the display shows 'CAL' during the calibration process.

5.2 القياس

The flat surface electrode allows for versatile measurements.

1. After calibration, rinse the electrode with distilled water.
2. اغمر القطب الكهربائي فيample to be measured. For liquids, ensure the electrode tip is fully submerged. For semi-solids or solids, ensure good contact with the flat surface electrode.
3. Allow the reading to stabilize on the display. The analog bargraph will indicate trends in acidity or alkalinity.
4. To switch between pH and temperature display modes, press the وضع زر.
5. After measurement, rinse the electrode thoroughly with distilled water and replace the protective cap.

6. الصيانة

6.1 Electrode Refilling

The refillable electrode design allows for prolonged accuracy and lifespan.

1. When the reference solution depletes or accuracy declines, use the provided removal tools to access the reference junctions.
2. Carefully refill the electrode with the 1.5mL KCI solution.
3. Ensure the reference junctions are properly re-seated after refilling.

6.2 التنظيف والتخزين

• Always rinse the electrode with distilled water after each use to prevent contamination.
• The flat surface electrode is designed for easy cleaning. Gently wipe with a soft cloth if necessary.
• Store the electrode with its protective cap filled with electrode storage solution (or pH 7 buffer if storage solution is unavailable) to keep the sensor hydrated. Do not store dry.

7. استكشاف الأخطاء وإصلاحها

If the meter exhibits inaccurate readings or operational issues, consider the following:

• قراءات غير دقيقة: Recalibrate the meter using fresh buffer solutions. Ensure the electrode is clean and properly hydrated. Check if the reference solution in the electrode needs refilling.
• لا توجد مشاكل في العرض/الطاقة: Verify that the batteries are correctly installed and have sufficient charge. Replace batteries if necessary.
• استجابة بطيئة: The electrode might be dry or contaminated. Clean and rehydrate the electrode, then recalibrate.
