TracWater TW-8214 Online Multi-parameter Sonde

Model number: TW-8214
Power: 0.8W (non-wiping), 2W (wiping)
Dimension: Φ84mm*476mm
Customise: OEM, ODM

Product description:
TracWater TW-8214 Online Multiparameter Sonde for Water Quality Monitoring, made for monitoring, long-term deployments, multiparameter data collection and transmission.

Overview

TracWater TW-8214 multi-parameter sonde features an integrated multi-in-one structural design. Each individual probe is an RS485 digital probe with calibration data stored directly in the single-parameter sensor. This allows for easy on-site calibration or replacement of each probe. The sonde supports online monitoring of multiple parameters, including temperature, pH, ORP, DO, conductivity, turbidity, chlorophyll, BGA, OIW, salinity, and depth. The main body can connect up to six probes, enabling simultaneous detection of seven parameters. Additionally, the TW-8214 is equipped with a self-cleaning brush that effectively cleans the measurement surface, removes bubbles, prevents microbial attachment, and ensures reliable performance across various water environments, such as wastewater treatment, surface water, oceanic, and groundwater monitoring.

Features

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

  • The main body supports connection to up to six probes for parameters such as DO, conductivity (salinity), turbidity, pH, ORP, chlorophyll, BGA, OIW, and depth.

  • Equipped with a self-cleaning brush for scheduled cleaning at predefined intervals, minimising errors caused by bubbles or contamination.

  • Each probe can be individually replaced, calibrated, and maintained on-site, offering flexibility and convenience.

  • Features an efficient acquisition algorithm with a system-wide response time of ≤30 seconds.
