Principle
The PHS-430 pH Meter is based on microcomputer technology and ensures measurement Stability through a high-input Impedance design (≥ 3 × 10 ^ 12 Ω). It uses Electrode to detect pH, mV, ORP and other parameters of aqueous solutions, combined with automatic temperature compensation (ATC) and Adjustment, to achieve accurate Multi-Parameter measurement and data management.
Applications
Light industry, chemical industry, food, environmental protection, education and scientific research departments
Steps
1. Press the switch button to turn it on, and the instrument can be connected to the AC220V socket through the Power Adapter in standby state.
2. Use the Mode key to switch the pH/pX/mV measurement and setting function of the instrument
3. Electrode correction is performed by pressing the Cal key in pH/pX state, and relative mV blank correction is performed in mV state
4. Use the number/letter/symbol keypad to set parameters, press Enter to confirm the setting or start the measurement
5. Measured value stable press M + key to store measurement information
6. Use the F1, F2, F3, and F4 keys to select the menu, and the ESC key returns to the previous level of operation
7. Select automatic measurement, real-time measurement or timing Measurement mode as needed
Notice
• If the Power Adapter is not unplugged from the AC220V socket after the instrument is turned off, the instrument is in micro-power standby state
• When setting parameters, use the Enter key to confirm that the parameters are valid
• In the measurement state, press Enter to start a measurement operation when the automatic end point is reached
• Ion concentration measurement using corresponding Ion Electrode
• The power requirements are DC9V 500mA, internal positive and external negative
