TracWater TW-8217 Multi-parameter Sonde for Deep Water

Model number: TW-8217
Power: 0.8W (non-wiping), 2W (wiping)
Dimension: Φ84mm*476mm
Customise: OEM, ODM

Product description:
The TW-8217 deep water multi-parameter sensor is designed with a sturdy and pressure-resistant structure and a self-developed titanium alloy watertight connector. It is specially tailored for deep water wells, oceans and other simlar environments.

Overview

The TracWater TW-8217 deep-water multi-parameter sonde features a robust structural design, an in-house developed titanium (Ti) waterproof connector, and is specifically engineered for deep water/well, marine, and other demanding working conditions. The main unit can connect up to six probes, with options including DO, pH, ORP, conductivity (salinity), turbidity, chlorophyll, BGA, OIW, and depth sensors, which can be freely selected based on application requirements. All probes are constructed from titanium, ensuring excellent corrosion resistance.

 

The TW-8217 is equipped with a self-cleaning brush that effectively cleans the measurement surface, removes bubbles, prevents microbial attachment, and ensures stable performance under underwater pressures of up to 200 meters. This makes it suitable for monitoring needs in deepwater lakes, oceanic environments, underground drilling, harsh wastewater treatment, and other mid-to-deep water scenarios.

Features

  • RS485 output with standard MODBUS protocol, facilitating seamless integration with data acquisition platforms and water quality automatic monitoring stations.

  • The main body includes six standardised probe interfaces and a central interface for the cleaning brush, enabling flexible plug-and-play functionality with TracWater probes and automatic identification.

  • All calibration parameters are stored within individual sensors, allowing for convenient on-site replacement, calibration, and maintenance.

  • The configured probes are all made of titanium, providing high-pressure resistance and reliable operation at depths of up to 200 meters underwater.
