Wide Measurement Range
Amtax sc Ammonia Analyzers are available in four measuring ranges. With detection limits as low as 0.02 mg/L and ranges up to 1000 mg/L, the Amtax sc can be used anywhere in the wastewater treatment process, from the influent or start of the nitrification process with high NH4-N levels to the effluent with only low ammonium levels. In the lowest range it can also be used for drinking water applications.
Easy Installation
The Amtax sc Analyzer is designed to be installed at the measuring location, including outdoor locations. The housing is weatherproof and lockable so that the analyzer can be installed right at the basin, even in the toughest climates.
The Amtax sc easily mounts to a wall, rail- and stand-mounting options are available. Due to its SC technology the analyzer is ready for use in the network of the SC controller ("plug-and-play").
Optional with Sample Preparation or Second Channel
The Amtax sc analyzer works with a low-maintenance filtration system (e.g. Filtrax) that removes particles larger than 0.15 µm. The filtrate is sent to the analyzer while air bubbles constantly clean the filtration membrane.
The analyzer is also available as two channel version for measurement at two different sampling points.
Fast Response Time for Control of Nutrient Removal Process
Nutrient removal is a critical and sensitive process in wastewater treatment. Quick response is vital for optimal operation. The fast response time of only 5 minutesand selection of the measurement interval, make the Amtax sc Ammonium Analyzer the fastest responding ammonia analyzer on the market.
Low Maintenance and Simple Operation
The analyzer calibrates and cleans itself automatically and is equipped with comprehensive self-diagnostic routines. With at least a 3-month supply of reagents (for 5 min interval), the Amtax sc analyzer offers the most economical reagent consumption. Reagents and wear parts are easily accessible.
