I. Product Introduction The Calcium Ion Detector is a reliable and precise instrument designed to measure calcium ion concentration in various liquid samples. It operates based on the electrode method, making it suitable for use in medical, environmental, and industrial applications. This device is ideal for analyzing calcium levels in water, blood, soil, and pharmaceutical solutions. Its user-friendly design ensures ease of operation, even for those with limited technical experience.
II. Technical Parameters
- Measuring Range: 0–1000 mg/L
- Resolution: 0.1 mg/L
- Repeatability: ≤2%
- Indication Error: ±5% FS ±1 digit
- Power Supply: AC 220V, 50Hz
III. Instrument Features
1. Equipped with a microcomputer and touch keyboard for intuitive operation.
2. The sensor uses a high-quality calcium ion-selective electrode, consisting of a measuring and reference electrode. It offers stable potential, fast response time, and easy handling.
3. Supports fully automatic three-point calibration. Once the reading stabilizes, the current value is automatically stored, and data remains intact after power-off.
4. High-resolution display allows accurate readings down to 0.1 mg/L.
5. Designed for long-term durability and consistent performance under different conditions.
IV. Water Sample Testing Procedure
To test a water sample, first rinse the electrode with deionized water and gently blot it with filter paper to remove excess moisture. Then immerse the electrode into the sample solution and press the "Read" button. The instrument will automatically display the stabilized measurement value once it's ready.
V. Precautions
1. Prepare three standard calcium chloride solutions before performing calibration.
2. Calibration and testing must be done using a magnetic stirrer to ensure uniform temperature, stirring speed, and ionic strength across all samples.
3. When testing, always clean the electrode thoroughly with deionized water and use filter paper to remove any residual moisture. Avoid mixing containers for diluted and concentrated solutions. Try to measure concentrated samples by diluting them appropriately.
4. It is recommended to calibrate the instrument before each test. However, if the interval between tests is short and the measured value falls within the acceptable error range, recalibration may not be necessary.
5. After use, clean the electrode with deionized water, dry it with filter paper, and store it in its protective case to maintain performance and prolong its lifespan.
Whether you're working in a lab or on-site, this Calcium Ion Detector provides accurate, fast, and reliable results. Its advanced technology and user-friendly interface make it an essential tool for professionals in various fields. Make sure to follow the guidelines carefully to ensure optimal performance and measurement accuracy.
