8222 Conductivity Meter
Brand: Burkert Fluid Control Systems
The Burkert compact meter Type 8222 is designed for measuring the conductivity of fluids. The conductivity meter consists of a sensor, plugged-in and pined to the transmitter (with removable display). The sensor comprises a cell with two electrodes and a Pt1000 temperature probe. The sensor itself is available with three different cell constants C, these with C = 0.01 or 0.1 are fitted with stainless steel electrodes and those with C = 1.0 are fitted with graphite electrodes.
The conductivity meter can operate independent of the display but it will be required for programming the device and also for visualizing continuously the measured and processed data.
Features- Perfect for clean water and slightly concentrated liquids
- Integral device for direct connection to PLC
- Simulation of process values for diagnostics
- Three cell constants to cover a wide application range e.g. reverse osmosis
