Product Description

The Hanna BL983321 TDS Mini Controller is an ideal solution for precise monitoring and control of very low TDS levels in sensitive water systems. Many users face problems like difficulty in maintaining ultra-pure water quality, manual monitoring errors, or inconsistent dosing control. This controller solves these issues by providing accurate and automatic TDS management in real time.

It is designed to measure TDS in the range of 0.00 to 19.99 ppm, making it perfect for applications such as laboratory water systems, reverse osmosis (RO), deionization plants, and high-purity water processes. Maintaining low TDS levels is critical in these applications to ensure system efficiency and product quality.

The Hanna BL983321 offers both automatic and manual control modes. In automatic mode, the controller activates a relay when TDS levels go beyond the set point, helping control dosing systems or alarms. This ensures consistent water quality without the need for constant supervision.

One of the key advantages of this controller is its compact and user-friendly design. It features a clear LCD display along with a multicolor LED indicator that quickly shows system status. The panel-mounted design makes installation simple and space-saving.

The device is built with a fire-retardant casing and a splash-resistant cover, ensuring safe and long-lasting performance. The labeled terminal connections allow quick and easy setup with compatible probes and control devices.

If you are facing issues like maintaining low TDS levels, manual errors, or system inefficiency, this product provides a simple and effective solution.

Set includes the panel-mounted controller with 12VDC adapter. Weight: 200 g. Suitable for use in industrial, laboratory, and commercial water quality management environments. Explore more process control instruments and industrial TDS analyzers in EnvMart's Mini Controllers category.
