  • Turbidity Analyzer (TU5300/5400) is designed to deliver a revolutionary 360° x 90° Detection Technology, engineered to see more of your sample than any other turbidimeter. This unique technology is used in both the TU5 online and TU5 benchtop turbidimeters, delivering the best low-level precision and sensitivity while minimizing variability from test to test. Suitable for drinking water and other clean water applications.
  • Silica 5500sc Analyzer requires only two liters of reagent for the analyzer to perform unattended for up to 90 days; features a pressurized reagent delivery system which eliminates the frequent maintenance associated with pumps. Predictive diagnostic tools, including Hach’s proprietary Prognosys technology, warning LEDs, and high-visibility notification screens let you avoid unplanned downtime.
  • HACH EZ Analyzer series covers a unique range of parameters (hardness, manganese, iron, color, and more) on a single analyzer platform. Five measurement technologies (colorimetry, titration, ion-selective electrode, voltammetry, and chemiluminescence) allow for a wide selection of measuring ranges and applications. All instruments come in the same rugged mainframe with a compact footprint.

Online Sensors


  • HACH pH or ORP (Digital Differential) sensors feature exceptional performance due to the Differential Electrode Measurement Technique. Sensors use three electrodes instead of the two normally used in conventional pH/ORP sensors. Process and reference electrodes measure the pH/ORP differentially with respect to a third ground electrode. The end result is unsurpassed measurement accuracy, reduced reference junction potential, and elimination of sensor ground loops. These sensors provide greater reliability, resulting in less downtime and maintenance.
  • HACH dissolved oxygen sensors (LDO sc) use luminescent technology for measuring DO. This optical probe has no membranes to replace or electrolyte solution to replenish, making it virtually maintenance free. They require no calibration for the entire 2-year life of the sensor cap, which means it is ready to start measuring your DO (Dissolved Oxygen) right out of the box.
  • HACH’s UVAS plus sc digital UV probe is designed for reagent-free determination of the organic load via the spectral absorption coefficient (SAC) in the medium or in the bypass. Reliable measurement values are immediately available due to the direct UV measurement. The low maintenance sensor is self-cleaning and with its stainless-steel housing even applicable in difficult environmental conditions.
  • HACH’s Solitax sc Suspended Solids and Turbidity sensor offers a broad application spectrum and is ideal for drinking water, wastewater, surface water, and sludge treatment applications. Using the infrared duo scattered light method, Solitax sc provides a unique colour – independent measurement of solids and a reliable sludge analysis. Available as an immersion or inline probe, for turbidity and solids measurement, in plastic or stainless-steel housing, with or without self-cleaning wiper device. The self-cleaning wiper ensures accurate results even in the presence of aggressive biological growth and gas bubbles.
test kits

Test Kits


  • Color disc test kits use a visual comparison method (color matching) to determine concentration. Simply add reagents to the sample, turn the wheel until the sample matches a reference color – concentration is displayed in a window. Each test kit includes apparatus, reagents, and instructions – all in a rugged carrying case. Available parameters include Chlorine, pH, Iron, Manganese, Tannin/Lignin, and more.
  • Digital titrator test kits use a high-precision dispensation device and replaceable titrant cartridges for highly accurate results in the field or lab. More than 50 different parameters and/or ranges are available to suit many testing applications. Quick-change cartridges allow the user to switch parameters in seconds, and each cartridge provides between 40-100 titrations, depending on sample concentration. Common parameters available include total hardness, chloride, sulfide, carbon dioxide, and acidity. Each kit includes comprehensive instructions, apparatus, reagents, and a rugged carrying case
  • Drop-count titration kits are a simple, easy, and cost-effective way to test for many common parameters, including chlorine, chloride, dissolved oxygen, carbon dioxide, sulfite, nitrogen, formaldehyde, and more. Kits can be used in the field or lab as a quick reference, or for simple yes/no confirmatory testing. Simply add titrant to the sample until you see color change. Instructions, apparatus, reagents, and carrying case are included in every kit.
  • Multi-parameter kits come complete with reagents, instructions, and a rugged Hach carrying case. Kits range from a few essential parameters (chlorine & pH) or a specific application, such as the Soil and Irrigation Water Test Kit (SIW-1). Multi-parameter kits use several of Hach’s platforms, such as the digital titrator, color disc, drop count titration and test strips for simplicity and accuracy. Applications include drinking water, soil testing, water quality, boiler water, education, ecology, surface water, stream survey, and more.
