Principle
The instrument is based on a high-input Impedance design (≥ 3 × 1012 Ω) and microprocessor control. Signals are collected through the Electrode interface and the temperature interface, and pH, mV, ORP and temperature measurements are performed using programmed algorithms. Response speed is improved with signal equilibrating function, and measurement accuracy is ensured through automatic temperature compensation (ATC) and buffer automatic identification.
Applications
Environmental protection, agricultural products, disease control, wastewater treatment, universities and scientific research
Standards
Chinese buffer standards (PH4.00, PH6.86, PH9.18)
Steps
1. Install 2 AA alkaline batteries or connect to a general power supply (DC5V, 300mA, internal positive and external negative)
2. Electrode and temperature sensor
3. Measurement mode (pH, mV, ORP or temperature) after power on
4. Perform 1/2/3 point calibration, the instrument automatically recognizes the buffer
5. Electrode immersion in the test solution for measurement
6. The instrument automatically stores measurement data, up to 200 sets can be stored
7. After use, the instrument will automatically shut down after 15 minutes
Notice
• Make sure the Electrode interface and temperature interface are connected correctly before use
Standard buffers (PH4.00, PH6.86, PH9.18) are required for calibration.
• Pay attention to temperature compensation settings during measurement (automatic/manual)
• Pay attention to waterproof and anti-corrosion when using in the field
• It is recommended to remove the battery when not in use for a long time
• Electrode converter or Ion selective electrode needs to confirm interface compatibility
