For water quality professionals struggling with unreliable dissolved oxygen readings, the Hach HQ1130 portable dissolved oxygen meter offers a transformative solution. This precision instrument delivers accurate, dependable measurements whether in challenging field conditions or controlled laboratory environments.

The Hach HQ1130 distinguishes itself through rugged construction and intuitive operation . With an IP67 protection rating, it withstands demanding field conditions from muddy construction sites to humid environments. The single-channel design focuses exclusively on dissolved oxygen measurement, eliminating unnecessary complexity while ensuring rapid deployment and reliable results.

The HQ1130 eliminates cumbersome manual recording with its integrated USB data transfer capability. With a single button press, measurement data transfers securely to computers or storage devices, streamlining analysis and reporting workflows for field technicians and researchers.

The meter's precision stems from Hach's proprietary IntelliCAL smart electrodes , which automatically recognize and store calibration histories and method settings. This innovative feature minimizes human error while ensuring consistent accuracy across measurements. The electrodes maintain exceptional performance even with complex samples or in challenging operating conditions.

While the HQ1130 specializes in single-parameter measurement, Hach's HQ series offers expanded capabilities through the HQ2000 (dual-probe) and HQ4000 (triple-probe with full-color display) models. These multi-parameter systems enable comprehensive water quality assessment with a single instrument, reducing equipment requirements and improving operational efficiency.

The HQ1130 and HQ series instruments serve critical roles across multiple water monitoring scenarios:

• Groundwater assessment for environmental protection and resource management
• Wastewater influent analysis to optimize treatment processes
• Municipal water supply quality assurance
• Primary and secondary wastewater treatment process monitoring
• Surface water quality evaluation in rivers, lakes, and reservoirs

Backed by over 80 years of electrochemical expertise, Hach provides comprehensive support services including technical assistance, field maintenance, and centralized service programs. This commitment ensures maximum instrument uptime, data integrity, operational stability, and regulatory compliance.

The system supports various optional accessories to meet specific operational requirements:

• IntelliCAL LDO/LBOD sensors with variable cable lengths
• Laboratory-grade or ruggedized field electrodes
• Protective cases, wrist straps, and mounting stands
• Complete BOD measurement kits including specialized bottles and stoppers

The Hach HQ1130 portable dissolved oxygen meter represents an optimal balance of measurement accuracy, field durability, operational simplicity, and data management efficiency. Its professional-grade performance makes it an essential tool for water quality assessment across multiple industries and applications.
