HACH HQ4000 Series Multimeter with ISE Capability

Description

The HACH HQ4000 Series is a high-performance range of multi-parameter electrochemistry meters designed for precise water quality analysis in both laboratory and field environments. The series supports a wide range of measurements, including pH, conductivity, dissolved oxygen, ORP, and ion-selective electrode (ISE) analysis. With full ISE capability, it enables accurate measurement of specific ions such as ammonia, ammonium, nitrate, chloride, fluoride, and sodium, making it ideal for advanced chemical monitoring and compliance testing.

The HQ4000 series includes multiple models tailored to different application needs. The HQ4100 is a single-input meter designed for straightforward, routine measurements of one parameter at a time. The HQ4200 expands functionality with dual-input capability, allowing users to connect two probes for increased flexibility. The HQ4300 offers enhanced performance with dual-channel measurement, enabling simultaneous analysis of two parameters, improving efficiency in busy laboratory or field workflows.

Built for reliability and ease of use, all models feature intuitive navigation, robust data management with GLP-compliant data logging, and compatibility with IntelliCAL® smart probes, which provide automatic sensor recognition and store calibration data directly on the probe. With a durable design and advanced functionality, the HQ4000 Series delivers consistent, high-quality results for environmental monitoring, industrial processes, and research applications.
