Overview
QIWEI PH-220W pen pH meter is an external Electrode Portable measuring instrument, Measurement accuracy of 0.01pH, compact size, easy to carry, simple operation, often used in field or field testing, can display PH value and temperature value at the same time, with high cost performance.
Features
1. Measurement accuracy up to 0.01pH
2. External Electrode Design
3. Compact size, easy to carry
4. Easy to operate, suitable for on-site use
5. PH value and temperature value can be displayed at the same time
6. Cost-effective
Principle
Based on the principle of electrochemistry, the product detects the concentration of hydrogen ions in the solution through external Electrode, converts it into pH value display, and integrates a temperature sensor to synchronize Measuring temperature.
Applications
Tap water source monitoring, aquaculture, printing and dyeing, environmental protection, Eletroplating, agriculture, beverages, R & D institutions
Standards
PH calibrated: three point calibrated (4.01, 6.86, 9.18)
Steps
1. Install 1.5V battery (LR44) * 4PCS
2. Perform PH three-point calibrating (4.01, 6.86, 9.18)
3. Electrode immersion in the solution to be tested
4. Read the displayed pH value and temperature value
Notice
• Operating Environment Temperature must be within the range of 0~ 50 ℃
• PH calibrated regularly to ensure Measurement accuracy
• Avoid Electrode Exposure to Air for a Long Time
• Operate the instrument correctly according to the specifications
