ZD03Water Monitoring
Digital Turbidity Transmitter
Digital turbidity transmitter for water quality monitoring uses 90° scattered light with infrared LED, offering 0–200 NTU or 0–1000 NTU ranges and ±5% indication value or ±3 NTU accuracy (0–1000 NTU), with RS-485 Modbus/RTU output. Built-in Pt1000 temperature compensation and two-point calibration support reliable online long-term environmental monitoring.
- Accuracy
- ±5% indication value or ±3 NTU, whichever greater (0–1000 NTU); ±3% of indication value or ±2 NTU, whichever greater (0–200 NTU); ±0.5 °C
- Range
- 0–1000 NTU or 0–200 NTU (by model)
- Output signal
- RS-485, MODBUS/RTU protocol
- Power supply
- 12 or 24 VDC ±10%, 10 mA
- Digital transmitter, directly outputs RS-485 signal, supports MODBUS/RTU
- 90° scattered light principle, built-in temperature auto compensation
- Optical fiber structure resists external light interference
- Infrared LED light source with filter design for stability
- Surface anti-corrosion passivation
- Low power consumption and internal circuit anti-interference design

ZD03 questions
What ranges are available for the ZD03?
Standard coverage is 0–1000 NTU or 0–200 NTU (by model). Other spans, outputs, and process connections can be sourced to match the application. Send the working pressure and medium and we will confirm the exact option.
What is the MOQ and lead time?
1 pc (flexible, no minimum for most products). 2-3 days for in-stock items, 15-30 days for custom orders. Samples are available, with freight on the buyer’s account.
Can the ZD03 be customized?
Range, output signal, process connection, cable length customizable through our supply partners.
Do you manufacture this transmitter?
SIBXSUN is an industrial instrumentation supplier in Ningbo, not the factory. We source the ZD03 from qualified partners, inspect before shipment, and handle export documents and logistics.
