KZEC-220 Non-Contact Conductivity Sensor
The KZEC-220 non-contact conductivity sensor features full electrical isolation performance.
It adds automatic temperature compensation and runs with low power consumption.
It works perfectly for industrial wastewater and media that easily form precipitation.
1. Core Advantages：
• Digital Output
This digital sensor sends data directly via RS‑485 port.
It fully follows and supports the MODBUS/RTU protocol.
• Automatic Temperature Compensation
A temperature sensor is built inside the probe body.
It carries out real-time temperature compensation during measurement.
• Non-Polarization
It adopts electrode-free structural design.
This method completely removes any polarization effects.
• Full Electrical Isolation
The measuring circuit is fully electrically isolated from the liquid medium.
It delivers high-precision reading for high-density and easy-to-precipitate liquids.
It also helps keep long-term maintenance cost at a low level.
• Low Power & Anti‑Interference
The whole device consumes very low power.
It is built with optimized circuit layout for stronger anti-interference ability.
