คุณสมบัติหลัก:

• Proprietary pH Sensor Technology: Utilizes advanced technology and premium materials from Switzerland for superior performance.
• Unique LabSen Blue Hemispherical Glass Membrane: Offers faster response rates, improved repeatability, and enhanced impact resistance, being 10 times stronger than traditional glass membranes.
• Long-Life Reference System: Designed to improve the stability of the reference electrode and prolong its service life.
• TRIS Buffer Compatible: Ensures accurate measurements even in complex buffer solutions.
• No Air Bubbles: Features a Swiss blue gel electrolyte that prevents air bubbles from forming inside the glass membrane, ensuring consistent stability.

การตั้งค่าและการใช้งาน

This section provides guidance on setting up and operating your LabSen 211 pH Electrode for optimal performance.

ตั้งค่าเริ่มต้น:

1. การแกะกล่อง: Carefully remove the LabSen 211 pH Electrode from its packaging.
2. การตรวจสอบ: Inspect the electrode for any visible damage. Ensure the glass membrane and body are intact.
3. การเชื่อมต่อ: Connect the standard BNC connector of the electrode to a compatible pH meter.
4. การชดเชยอุณหภูมิ: Note that this electrode does not have a built-in temperature sensor. For accurate readings, use a separate temperature probe (e.g., Apera MP500) for Automatic Temperature Compensation (ATC) or manually input the temperature into your pH meter.

Operating Principles and Applications:

The LabSen 211 pH Electrode is designed for a wide range of applications. The following video provides an overview of its features and diverse uses:

1. General Water Solutions:

Ideal for pools, wastewater, hydroponics, aquariums, beverage, aquaculture, environmental monitoring, TRIS buffer, titration, etc. The low-resistance glass membrane and patented pH/Temp. rapid sensing structure ensure reliable measurements.

2. Low Ion Concentration Solutions:

The exquisite structure ensures fast reading stabilization for low ion concentration solutions such as RO water, distilled water, deionized water, storm water, and ground water.

3. Strong Acid / Basic, High Temp, Complex Solutions:

Special HF and HA glass membranes are designed for strong acid, strong base, and high-temperature solutions, including those containing hydrofluoric acid, used in electroplating, battery electrolyte, and industrial wastewater.

4. Micro-volume Sampเลส:

For testing micro-volume samples in test tubes, microplates, NMR tubes, cuvettes, and centrifuge tubes, an ultra-slim yet strong glass membrane with fast response is required.

5. Solid & Semi-solid Samples and Flat Surface:

Direct pH measurement of solid, semi-solid, and flat media like cheese, meats, fruits, dough, soil, sushi, skin, textiles, paper, and fabrics requires different types of spear and flat electrodes.

6. Viscous & Dairy Sampเลส:

For viscous and dairy samples such as coatings, resin, syrup, chocolates, sauce, milk, yogurt, and cream, the pre-pressurized reference system and Protelyte electrolyte provide the best solution to prevent junction clogs.

การซ่อมบำรุง

Proper maintenance ensures the longevity and accuracy of your LabSen 211 pH Electrode.

• พื้นที่จัดเก็บ: Always store the electrode in its protective cap with the recommended storage solution to keep the glass membrane hydrated.
• การทำความสะอาด: Regularly clean the electrode tip with distilled water after each use. For stubborn residues, refer to specific cleaning solutions recommended by Apera Instruments.
• ระดับอิเล็กโทรไลต์: Ensure the electrolyte level is always above the reference wire. Refill if necessary with the appropriate electrolyte solution.
• การสอบเทียบ: Calibrate the electrode regularly according to your pH meter's instructions and application requirements to maintain accuracy.

การแก้ไขปัญหา

If you encounter issues with your LabSen 211 pH Electrode, consider the following common troubleshooting steps:

• การอ่านค่าที่ไม่เสถียร: Ensure the electrode is properly hydrated. Check for air bubbles in the electrolyte. Verify the temperature compensation settings.
• การตอบสนองช้า: Clean the electrode tip. Re-calibrate the electrode. Ensure the sampอุณหภูมิคงที่
• การอ่านค่าที่ไม่ถูกต้อง: Perform a fresh calibration with new buffer solutions. Check the integrity of the electrode's glass membrane. Ensure the sample is well-mixed and free of interferences.
• ไม่ต้องอ่าน: Check the BNC connection to the pH meter. Ensure the pH meter is powered on and functioning correctly.
