Septal polarographic sensor
The Dulcotest diaphragm polarograph sensor selectively detects the substance to be measured using the proprietary diaphragm technology. Equipped with an accurate signal conversion function, it realizes speedy and stable measurement.
Features
● Since the measurement target is detected via the diaphragm and electrolyte, stable measurement is possible without being affected by conductivity.
● Economical consumables with only membrane cap and electrolyte
● Electrodes have a long life because there is no sliding of beads, etc.
● Built-in converter in the sensor・The sensor can be installed separately from the display meter
It is a global standard sensor that supports various applications with a wide lineup of measurement ranges and targets.
