Overview
The QIWEI PH-20W pH meter is a pen acidity meter with +/- 0.1pH Measuring accuracy for simultaneous measurement of PH value and temperature value. Compact and portable, the product is suitable for outdoor or field test operations. It is widely used in water quality PH value measurement in tap water, aquaculture, environmental protection, agriculture, printing and dyeing, Eletroplating, beverages and R & D institutions. Accurate and reliable measurement, using external Electrode design.
Features
1. Measuring accuracy of +/- 0.1pH, Reliability
2. Simultaneous measurement of pH value and temperature value
3. Compact size, easy to carry, suitable for outdoor or outdoor use
4. External Electrode Design
5. The power supply is 1.5V battery (LR44) * 4PCS, which is easy to operate
6.Light weight, only 88g, easy to hold
7. Support PH three-point calibrated (4.0, 6.9, 9.2)
Principle
PH-20W pH meter detects the hydrogen ion concentration in the water sample by external Electrode, and converts it into PH value display; at the same time, the built-in temperature sensor measures Ambient Temperature to achieve simultaneous measurement of PH and temperature.
Applications
Tap water, aquaculture, environmental protection, agriculture, printing and dyeing, Eletroplating, beverages, R & D institutions
Steps
1. Install 1.5V battery (LR44) * 4PCS
2. Perform PH three-point calibrating (4.0, 6.9, 9.2)
3. Electrode immersion in water sample to be tested
4. Read PH value and temperature value display
5. Clean Electrode After Use and Store Properly
Notice
• Permissible Ambient Temperature is 0~ 50 ℃, avoid using beyond the range
• The calibrating point needs to be carried out at 25 ° C to ensure accuracy
• Regularly check the battery power and replace it in time
• Clean Electrode in time after use to prevent contamination
• Avoid violent vibrations or falls to protect the instrument
Store in a drying environment to extend service life
