Introduction：
Online Magnesium Ion Analyzer measures magnesium ions in liquids with an ion-selective membrane and 24-bit ADC for precise measurement. Widely used for drinking water, wastewater, environmental protection and industrial water monitoring....
The online magnesium ion analyzer is a precision instrument for the determination of magnesium ion concentration in liquids. A magnesium ion selective membrane is fitted at the front of the sensor. When the sensor is immersed in the sample, magnesium ions in the sample diffuse through the selective membrane into the internal electrolyte, where the cation activity rises and creates a small potential difference against the reference electrode. This potential difference is proportional to the magnesium ion concentration. The circuit amplifies the potential difference and converts it into a direct concentration reading.
1. LCD screen with a Chinese interface, making operation simple and convenient.
2. High-precision 24-bit ADC signal acquisition and anti-interference circuit for higher precision and greater stability.
3. Photoelectrically isolated 4–20 mA current output and RS-485 / RS-232 communication interface.
4. Optional upper-computer online acquisition software from our company for data acquisition and analysis.
5. One-key calibration with standard solution; built-in watchdog with data retention exceeding 10 years after power failure.
6. Dual-relay upper and lower limit alarm output.
7. The sensor is temperature-compensated, which corrects the influence of temperature on the measured value.
8. Special functional requirements can be customised.
