Product Introduction
The DS300 is based on advanced sensor technology for in-situ water quality analysis. It is portable and suitable for long-term use in measuring temperature, depth (liquid level), conductivity (specific conductance, TDS, salinity), pH, ORP (oxidation-reduction potential), dissolved oxygen, and a range of other water quality parameters. The sensor has a diameter of 58.5 mm, making it applicable for various water quality testing scenarios.
Product Features
Compact stainless steel housing, highly portable.
Bluetooth-connected mobile app (with accompanying app).
Waterproof rating of IP68, with plug-and-play probes, stable measurements, and strong interference resistance.
Utilizes RS485 interface and standard Modbus RTU protocol for real-time data transmission.
The electric cleaning brush ensures that the measurement window is clean, preventing microbial growth and reducing labor costs.
Customizable high-strength cables, equipped with quick-release twist-lock connectors for easy plug-and-play in the field, effectively improving on-site work efficiency.
Wide application range, suitable for portable field use or long-term deployment for online monitoring.
