The Amtax Ammonia Analyzer is on Phase Out and will soon be obsolete. Hach now offers the advanced NH6000sc Ammonia Analyzer as a replacement. Available in 230V (LXV461.99.00211) and 115V (LXV461.99.00221) models to meet your needs.
The Hach Amtax sc Ammonia Analyzer, with a 0.05 – 20.0 mg/L detection range and fast response time that includes sample preparation, is ideal for precise ammonia measurement in wastewater applications. The analyzer is environmentally controlled for rugged, outdoor installations and designed for easy installation at the measurement point. Its probe features a self-cleaning membrane, requiring minimal maintenance, and provides easy access to reagents and wear parts.
Transitioning to the NH6000sc Ammonia Analyzer
As the Amtax sc is being phased out, Hach introduces the NH6000sc—our newest ammonium analyzer. The NH6000sc builds on the trusted reliability and low maintenance of the Amtax, now with enhanced features and a modern design
