Overview
The QIWEI PH-20 is a pen acidity meter with a Measuring accuracy of +/- 0.1pH, which can simultaneously measure PH value and temperature value. The product is compact and easy to carry. It is commonly used in outdoor or field test operations. It is suitable for monitoring the pH value of water quality in tap water, aquaculture, environmental protection, agriculture, printing and dyeing, Eletroplating, beverages and R & D institutions. The measurement is accurate and reliable. Built-in Electrode.
Features
1. Measuring accuracy is high, pH Measurement accuracy is +/- 0.1pH
2. Simultaneous measurement of pH value and temperature value
3. Compact size, easy to carry, suitable for outdoor or outdoor use
4. Built-in Electrode Design
5. The power supply adopts 1.5V battery (LR44) * 4PCS, which is easy to operate
Principle
PH-20 pen acidity meter through the built-in Electrode detection of hydrogen ion concentration in the water sample, converted to PH value display; while integrating temperature sensor, measurement environment or water sample temperature, to achieve simultaneous measurement of PH and temperature.
Applications
Water monitoring, aquaculture, environmental protection, agriculture, printing and dyeing, Eletroplating, beverages, R & D institutions
Steps
1. Boot preparation: install 1.5V battery (LR44) * 4PCS
2. calibrating: three-point calibrating at 25 ° C (pH value 4.0, 6.9, 9.2)
3 measurement: Electrode immersion in the water sample to be tested, read the pH value and temperature value
4. Clean Electrode and shut down after use
Notice
• Permissible Ambient Temperature Range 0~ 50 ℃, avoid use in environments beyond the range
• calibrated at 25 ° C to ensure measurement accuracy
• Electrode cleaning in time after use to prevent contamination from affecting the next measurement
• Regularly check the battery power to ensure normal power supply
