The Hach EZ Series Ammonium Analysers provide reliable, continuous online monitoring of ammonium and ammonia (NH₄/NH₃) across a wide range of water and wastewater applications, including municipal wastewater treatment, drinking water, power generation, semiconductor manufacturing, oil and gas, and food and beverage processing. The family includes two distinct products: the EZ1102sc, which uses colorimetric analysis for low-level ammonium detection, and the EZ4005, a single-parameter online titrator designed for high-concentration measurements.
The key factor to consider when selecting a model is your sample's expected concentration range. Applications requiring trace-level monitoring at or below 1 mg/L NH₄-N are best served by the EZ1102sc, while processes involving high concentration ammonium streams in the range of 100 to 5,000 mg/L NH₄-N call for the EZ4005.
Which Analyser Should I Choose?
EZ1102sc Ammonium Colorimetric Analyser
Choose the EZ1102sc for continuous, low-level ammonium monitoring in water and wastewater processes.
The EZ1102sc detects ammonium at concentrations from 0.005 to 1.0 mg/L NH₄-N (no dilution), with internal dilution options extending the range up to 100 mg/L NH₄-N. Operated with the SC4500 Controller, it supports one to eight sample streams and offers robust connectivity through Modbus RTU, Modbus TCP/IP, Profibus DP, and Ethernet/IP.
This analyser is the right choice when your process requires precise, permit-sensitive nutrient monitoring at low concentrations. Its user-friendly interface, minimal maintenance requirements, and scalable multi-stream configuration reduce both operational burden and cost per sampling point.
EZ4005 Ammonium Analyser
Choose the EZ4005 for high-concentration ammonium analysis in demanding industrial environments.
The EZ4005 is a single-parameter online potentiometric titrator with a standard measuring range of 100 to 5,000 mg/L NH₄-N. Optional calibration ranges of 10 to 500 mg/L, 25 to 1,250 mg/L, and 50 to 2,500 mg/L NH₄-N provide flexibility to match your specific process conditions. A high-precision dispenser and robust peristaltic pumps ensure consistent, accurate results across demanding sample matrices.
This analyser is the right choice when your process involves high concentration ammonium streams where low-range colorimetric methods are not suited to the concentration levels involved. Its automatic validation, priming, and cleaning routines maximise uptime and minimise the need for operator intervention. Separate electronic and wet-chemical compartments reduce the risk of cross-contamination, and a transparent door allows for quick visual inspection.
