In challenging field environments, the accuracy and efficiency of water quality monitoring cannot be compromised. Professionals frequently grapple with equipment failures, cumbersome data management, and unintuitive interfaces. The Hach HQ1130 Portable Dissolved Oxygen Meter addresses these challenges by combining rugged design with cutting-edge technology, delivering an unparalleled field measurement experience.

Engineered for Field Reliability

The HQ1130 is a single-channel meter equipped with a durable optical dissolved oxygen probe, designed specifically for rigorous field use. With an IP67 protection rating, it withstands rain, mud, and other harsh conditions while maintaining stable operation. Its intuitive USB data transfer capability simplifies exporting measurements for subsequent analysis.

For users requiring multiparameter measurements, the Hach HQ series offers advanced solutions. The HQ2000 model supports dual-probe simultaneous measurement, while the HQ4000 accommodates three probes and features a larger full-color display for enhanced visibility and usability.

Key Features and Benefits

Simplified Calibration Process

Most measurement errors originate from improper calibration. The HQ series eliminates this risk through intuitive, step-by-step on-screen calibration guides with troubleshooting assistance, ensuring consistent success rates.

Streamlined Data Management

Whether in laboratories or field locations, the USB interface securely transfers data, making routine tasks more efficient. The system stores up to 5,000 data points with comprehensive GLP functionality.

Versatile Sensor Compatibility

The HQ series supports standard laboratory and rugged field IntelliCAL® smart sensors for measuring total dissolved solids (TDS), optical dissolved oxygen (DO), biochemical oxygen demand (BOD), temperature, conductivity, and pH. These automatically recognized probes retain calibration history and method settings, minimizing errors and setup time.
