Product Overview:

The HACH EZ4000/5000 series is a dedicated online monitoring device for multiple water quality scenarios, including hardness testers (EDTA colorimetric / optical colorimetric titration method) and alkalinity testers (acid-base titration method). It supports single/multi-parameter configuration and up to 8-channel analysis. Through intelligent control via industrial flat panels, it adapts to wastewater, drinking water, industrial process water, and other scenarios, continuously monitoring hardness and alkalinity 24 hours a day, providing precise data for compliance control and process optimization.

Measurement Method:

The EZ4000/5000 series water hardness testers use EDTA colorimetric titration and optical colorimetric titration methods respectively for water hardness testing; The EZ4000/5000 series alkalinity testers use pH-base titration for total alkalinity determination.

Instrument Features:

The EZ4000/5000 series water hardness testers/alkalinity testers combine expertise in online titration with a range of analysis, control, and communication functions. The distributor, peristaltic pump, and flow path are ingeniously designed with high-quality materials.

● Flexible titration methods are used to meet the needs for varying water hardness testing and total alkalinity determination;

● Choose single-parameter or multi-parameter configurations as needed, supporting multi-channel analysis (8 channels available);

● Built-in intelligent automatic control system, with control and communication via industrial panel PCs;

● Standard 4-20mA signal output with alarm function, automatic warning for parameter exceedance, and process linkage adjustment;

● Supports Ethernet connection to Modbus TCP/IP communication.

Application Areas:

The EZ4000/5000 series water hardness testers / alkalinity testers are suitable for water hardness testing and total alkalinity determination of different water qualities such as wastewater, drinking water, surface water, and industrial processes.
