The HA-HC Meter Controller is a high-performance, handheld data logger and universal transmitter designed for robust environmental monitoring and industrial process control. As a core component of the Hydro-Air sensors ecosystem, this versatile HA-HC Transmitter connects seamlessly to a wide array of water quality sensors and other Modbus RTU devices. It delivers real-time data visualization, advanced control capabilities, and reliable wireless data transmission via 4G, Wi-Fi, and Bluetooth, making it an ideal all-in-one solution for field and remote applications.

The HA-HC Meter Controller is the perfect central hub for a wide range of monitoring and control scenarios, especially those involving water quality sensors:

• Water Quality Monitoring Networks: Ideal for continuous monitoring of parameters like COD, pH, turbidity, and dissolved oxygen in rivers, lakes, and wastewater treatment plants.

• Industrial Process Control: Used to calibrate sensors, adjust setpoints, and automate control sequences (e.g., activating cleaning brushes) in industrial settings.

• Remote Environmental Data Acquisition: Its 4G capability makes it a reliable data logger for transmitting information from remote, unmanned sites to a central office.

• Research and Portable Testing: Serves as a portable lab station for researchers and technicians using Hydro-Air sensors for on-site analysis.
