Overview
QIWEI PH-220 pen pH meter is a Portable instrument with measurement accuracy of 0.01 pH, built-in Glass electrode, small size, easy to carry, simple measurement, often used in field or field detection operation, can display PH value and temperature value at the same time, cost-effective.
Features
1. Measurement accuracy up to 0.01pH
2. Glass electrode, compact size, easy to carry
3. PH value and temperature value can be displayed at the same time
4. Cost-effective
5. Support three point calibrated (4.01, 6.86, 9.18)
6. The power supply adopts 1.5V battery (LR44) * 4PCS, which is convenient for on-site use
Principle
The QIWEI PH-220 pen pH meter detects the hydrogen ion concentration of the solution through the built-in Glass electrode, converts it into a pH value display, and integrates a temperature sensor to measure Ambient Temperature.
Applications
Tap water source monitoring, aquaculture, printing and dyeing, environmental protection, Eletroplating, agriculture, beverage and R & D institutions
Steps
1. Turn on the power switch
2. Electrode immersion in the solution to be tested
3. Record the pH value and temperature value after waiting for the reading to stabilize
4. Clean Electrode and Power Off After Use
Notice
• Avoid Electrode Exposure to Air for a Long Time
Periodic three-point calibrating to ensure measurement accuracy
• Electrode cleaning after use to prevent contamination
• Operates within the Permissible Ambient Temperature Range of 0~ 50 ° C
• Pay attention to the positive cathode direction when replacing the battery
