Overview
SMART SENSOR AS218 PH value detector is a Portable PH measurement device, Measurement range 0.00~ 14.00, powered by 9V battery, Net weight 205g, Dimension 159 * 66 * 31mm, suitable for PH value detection in various environments.
Features
1. Wide range pH measurement: 0.00~ 14.00
2. High Stability: Zero drift +/- 0.03
3. Low measurement error: intrinsic error +/- 0.05
4. Automatic temperature compensation: solution temperature compensation range 0~ 60 ℃
5. Portable Design: Lightweight and Easy to Carry, Color Box Encasement
6. Strong environmental adaptability: Permissible Ambient Temperature 0~ 35 ℃, relative humidity 0~ 80% RH
Principle
Electrode measurement of the concentration of hydrogen ions in the solution converts to PH value display. The built-in temperature sensor automatically compensates for the effect of solution temperature on PH measurement, ensuring measurement accuracy under different temperature conditions.
Applications
Water quality testing, laboratory analysis, industrial process control, environment monitoring, agricultural irrigation, Food processing
Steps
1. Turn on the device power supply
2. calibrated PH Electrode (if required)
3. Electrode immersion in the solution to be tested
4. Record the PH value after waiting for the reading to stabilize
5. Clean Electrode and Power Off After Use
Notice
• Avoid Electrode Exposure to Air for a Long Time
Periodically calibrated to ensure measurement accuracy
• Electrode cleaning after use to prevent contamination
• Operate within Ambient Temperature and Humidity ranges
• Pay attention to the correct polarity when replacing the battery
