Online Analyzers: EZ Series Analyzers EZ Series Hardness Analyzers EZ Series Hardness Analyzers Overview Downloads Accessories Gallery Help The EZ Series Online Analyzers 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 Analyzers 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 Analyzers 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 Analyzers 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 40 - 1000 mg/L Options for all analyzers 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.
