The Model sc100 Controller receives data from one or two sensors and is the best value water quality controller on the market. Its 'plug-and-play', 'mix-and-match' operation lets it fit into any facility or workflow. Digital communication with any Hach digital sensor or probe is simple and reliable.

The sc1000 Display Module is a full-featured controller with a large color touch-screen display. The intuitive, easy to use interface can be used for any number of parameters. One Display Module controls either a single Probe Module or a number of Probe Modules connected by a digital network.

Each sc1000 Probe Module provides power to the system and can accept up to 8 digital sensors. Probe Modules can be networked together to accommodate many more sensors attached to the same network.

Note: The Display Module and Probe Module must be ordered separately

Breakthrough Luminescence Technology for Measurement of Dissolved Oxygen

The HACH LDO dissolved oxygen probe applies new luminescence technology to continuously monitor dissolved oxygen. The instrument controller can inform staff immediately of any changes in DO level, and can be integrated with a variable frequency drive or PLC control system to control the amount of oxygen being injected into the system. The instrument can be used effectively in a range of demanding applications:

Features

• No calibration for one year
• Reduced cleaning frequency and simple maintenance
• 99% accuracy
• No electrolyte solutions to poison or replenish
• No membranes

Applications

• Aeration Tanks
• Collection systems - control odor by using in conjunction with a compressor and diffuser readings.
• Nitrification and denitrification tanks
• Aerobic and anaerobic digesters
• Up and Downstream from plant effluent (NPDES Permit Monitoring)
• Plant outfall (NPDES Permit Monitoring)

The HACH LDO dissolved oxygen probe requires minimal maintenance and infrequent calibration, and offers exceptional accuracy and repeatability.

The Model D4500 Dissolved Oxygen Analyzer is compact, full-featured, simple to install and easy to use. A user-friendly interface provides a full range of easily adjustable outputs, calibration and display options at your fingertips.
Orbisphere´s patented polarographic sensor design is a proven performer wherever knowledge of DO2 content is critical. It is fully compatible with existing Orbisphere flow chambers and process access devices. With its screw-on protection cap, the sensor yields expected in-service intervals of up to a year.

The 1720E Low Range Process Turbidimeter provides the sensitivity, stability and flexibility necessary to continuously track the low levels of turbidity found in high-quality filtered water. Equipped with the new dual-input digital sc100 controller, the 1720E is easy to calibrate and operate, and requires very little maintenance. With an optional network card the 1720E communicates via Lonworks directly with existing 1720D AquaTrend systems. A basic system consists of one sc100 Controller and one 1720E Turbidity sensor. The addition of a second 1720E turbidity sensor gives you two complete turbidimeters.

Features

• Meets and exceeds USEPA Method 180.1 for measuring turbidity for drinking water compliance
• One controller accepts up to two plug and play sensors giving you two complete turbidimeters
• Sensitive to fine changes in low level turbidity with a built-in bubble removal system
• Built-in datalogger stores up to 6 months of data
• Versatile digital output-MODBUS protocol, LonWorks or wireless IR port

Measure turbidity and suspended solids - with no color interference.

Hach's SOLITAX sc Suspended Solids and Turbidity Analyzer makes it easy to measure sludge concentration and turbidity values in wastewater, drinking water, and manufacturing processes. Whether you need to assess activated sludge and the entire biological cleaning stage, analyze the purified discharge of wastewater treatment, or monitor sludge at various stages of concentration, the SOLITAX sc Suspended Solids and Turbidity Analyzer gives you accurate and continuous measurements - completely independent of color.

Hach's SOLITAX sc Suspended Solids and Turbidity Analyzer automatically compensates for changes in activated sludge color caused by variations in through-flow volume, annual climatic fluctuations, or other unexpected events. Unlike conventional systems which require you to continually compensate for color variation, the proven "measured value constancy" and "measured value reproducibility" of the SOLITAX sc Suspended Solids and Turbidity Analyzer allows you to improve overall plant efficiency with faster, more reliable analysis and lower costs for operation and maintenance.

Features

• EPA-approved Method 180.2 (GLI Method 2)
• Provides accuracy and stability with the patented four-beam technology
• Verification with the patented Cal-CubeTM Assembly provides factory-certified, 100% reproducible NTU value
• Integral bubble trap
• Color Compensation
• Long lasting LED light sources
