Water Quality Monitoring Panels offer application specific Hach® sensor and electrode configurations in the convenience of one panel and are pre-engineered, ready to install, simple solutions - that are designed to work together.

Continuous UV 254 Absorbance/Transmittance measurements can be used to protect plant treatment processes from high organic loads. Analysis range of 50 mm probe is 0.01 - 60 m^-1. Use for the following applications: protection of treatment plants from industrial dischargers, monitoring shock loads from internal plant processes, control of activated sludge processes, control methanol feed in BNR based on organic loading, final effluent monitoring and monitoring efficiency of UV disinfection processes.

Meet your unique water cycle needs with the new Ultra Low Range CL17sc online total chlorine analyzer from Hach. Whether treating utility water, product water, or wastewater discharge, you’ll have the direct chlorine measurements you need to optimize your process. You’ll be able to protect valuable assets and report to regulatory agencies with confidence.

The HQ Series is for water quality professionals who want to perform electrochemical analysis for field and lab environments. Our new portable platform will allow you to collect intuitive, accurate measurements, manage data, and easily review results, while supplying an IP67 robustness rating.

Complete more tests on site, get the results you need faster, allowing you to visit more sites in each shift. Perform up to four colorimetric and two probe-based measurements in parallel 75% faster than with other methods.

The launch of the world’s first ready-to-use reagent packages for photometric analysis in the 1960’s had a substantial effect on water analysis. Today Hach^® TNTplus^® Vial Tests and photometers are indispensable elements of both process control and compliance monitoring.

The DR6000™ is the industry’s most advanced laboratory spectrophotometer for water testing. It offers high-speed wavelength scanning across the UV and Visible Spectrum, and comes with over 250 pre-programmed methods including the most common water and environmental testing methods used today. 

The DR3900 is a benchtop visible spectrum (320 - 1100 nm), split beam spectrophotometer with over 220 pre-programmed methods optimized for laboratory water analysis. With your daily routine of water analysis in mind, the DR3900 spectrophotometer is optimized for safe processes and accurate results.

Amtax Analyzer offers a wide measurement range for a variety of wastewater applications. It produces a fast response time that includes sample preparation. It is environmentally controlled for rugged, outdoor installations and designed specifically for easy installation at the measurement point. The probe is equipped with a self-cleaning membrane, and thus requires little maintenance. Analyzer features easy access to reagents and wear parts.

The PHOSPHAX sc Phosphate Analyzer is environmentally controlled for rugged, outdoor installations, provides a wide measurement range for a variety of wastewater and drinking water applications (e.g. in the activated sludge basin, for phosphate elimination and my more), and comes with the fully featured "Plug & Play" digital controller. 

The hand-held DR 900 allows quick and easy access to your most-used testing methods. This colorimeter is waterproof, dustproof and field durable.

Weighing only 28 pounds (12.7 kg), the AS950 Portable Sampler is designed for accuracy and convenience. Quickly switch between composite and discrete sampling in the field. Configurable for single- or multiple-bottle applications, it is specifically designed for use in 18-inch manholes.

The Hach TSS Portable Hand-held Turbidity, Suspended Solids, and Sludge Blanket Level Instrument's unique multi-beam alternating light method with infrared diode system gives it a broad measuring range for both turbidity and suspended solids in one portable handheld instrument.

Compliant with ISO Method 7027-1 and perfect for membrane filtration applications, the TU5400sc employs a patented optical design that sees more of your sample than any other turbidimeter, delivering the best low level precision and sensitivity while minimizing variability between measurements.

Excess ammonia in receiving waters causes algal blooms that decrease oxygen levels. For this reason, many wastewater treatment plants (WWTPs) must limit ammonia in discharge. Mike Rousey, Hach Company

Adjusting chemical dose based on flow or setting a fixed chemical dose can be very expensive. With a system that provides Real-Time Control, you can significantly lower chemical costs, quickly adjust for loading changes, and enjoy the peace of mind in knowing your effluent phosphorus levels are within permit range.

Harboes Bryggeri A/S was facing challenges with the performance of its wastewater treatment plant, due to the highly variable Chemical Oxygen Demand (COD) load in the inlet.
