EZ Series Hardness Analysers

The EZ Series Online Analysers offer multiple options to monitor Total Hardness and Calcium Hardness in water. Typical applications are wastewater, drinking water, steam & power generation, surface water.

The EZ1000 Series Hardness Analysers use colorimetric analysis:
- EZ1016 Total Hardness
- EZ1017 Calcium Hardness
- EZ1304 Total Hardness & Calcium
- EZ1306 Total Hardness & Calcium & Magnesium
Standard measuring range: 0.025 - 1 mg/L CaCO3

The EZ4000 Series Hardness Analysers are single-parameter titrators:
- EZ4043 Total Hardness; calmagite / EDTA method with LED dipping probe; standard measuring range: 0.25 - 10 mg/L CaCO3
- EZ4041 Total Hardness; calmagite / EDTA method; standard measuring range: 100 - 1000 mg/L CaCO3
- EZ4044 Calcium Hardness; standard measuring range: 10 - 1000 mg/L CaCO3

The EZ5000 Series Alkalinity Analysers are multi-parameter titrators:
- EZ5003 Total Hardness & Free Alkalinity
- EZ5004 Total Hardness & Total Alkalinity
- EZ5005 Total Hardness & Total Alkalinity & Free Alkalinity
- EZ5006 Total Hardness & Total Calcium Hardness & Total Alkalinity & Free Alkalinity
Standard measuring range Hardness: 25 - 1000 mg/L CaCO3, Alkalinity: 100 - 5000 mg/L CaCO3

- EZ5002 Total Hardness & Total Calcium Hardness, standard measuring range: 100 - 1000 mg/L CaCO3
- EZ5011 Total Hardness & Total Alkalinity, standard measuring range Hardness: 25 - 1000 mg/L, Alkalinity 20 - 1000 mg/L

Options for all analysers include:
- Calibration to 10% (not EZ5011), 25% or 50% of standard range
- Multiple stream analysis (1-8 streams) reducing cost per sampling point
- Analogue and/or digital outputs for communication

Some applications may require the use of a sampling/filtration or an external dilution system for sample preconditioning. For this option please check the EZ9000 Sample Preconditioning page.
