Conductivity/TDS Meter
Model No.:JM-3201
Widely used in enterprise sewage, domestic sewage, surface water monitoring,
Detailed Description
1.Product overview:
- New waterproof, dustproof, and moisture-proof high-quality housing (IP65) construction, with a painted surface finish.
- The product has strong anti-interference capabilities.
- Large-screen dot-matrix LCD display, supports Chinese and English menus (switchable), and displays multiple parameters simultaneously.
- Capable of measuring conductivity/TDS, upper/lower limit control, and automatic range switching, enhancing the product’s measurement resolution.
- The screen displays alarm status and simultaneously outputs ON/OFF switch signals.
- Automatic temperature compensation function: automatic 0–100°
- Communication functionality: Both RS485 and 4-20mA interfaces utilise optical isolation technology. The RS-485 communication interface is compatible with part of the MODBUS protocol (optional) and can be converted to RS-232. The conductivity/TDS values corresponding to the 4-20mA current output can be arbitrarily set. Supports both internal company IoT and customer-customised IoT.
- Arbitrary hysteresis setting functionality to prevent frequent switching of the relay.
- Customizable wide measurement range (within 0-300 mS·cm⁻¹).
- Watchdog function: Ensures the instrument does not freeze.
- Factory reset capability. Power failure protection > 10 years.
