Thermo Fisher Scientific - Thermo Scientific Orion AQUAfast Colorimeter

• Water treatment plants utilise colorimeters for routine monitoring of various parameters like chlorine, pH, and turbidity.
• Environmental laboratories employ these devices for analysing water samples from rivers, lakes, and industrial effluents.
• Food and beverage production facilities use colorimetric methods for quality control, such as checking colour consistency or detecting contaminants.
• Educational institutions and research facilities apply colorimeters for teaching purposes and basic analytical chemistry experiments.
• Industrial process control benefits from colorimeters for monitoring chemical concentrations and ensuring process efficiency.

Typical measurement range

Varies significantly by parameter, but typically covers common environmental and industrial analytes at trace to moderate concentrations.

Power supply

Commonly battery-operated for field use, with an option for mains power via an adapter for laboratory applications.

Wavelengths

Units of this type typically feature a selection of specific wavelengths or a broad-spectrum LED for various colorimetric tests.

Sample volume

Typically requires small sample volumes, often in the range of 5-10 ml, for cuvette-based measurements.

Display

Commonly features a clear LCD display for easy reading of results and menu navigation.

Data storage

Many units offer internal data logging capabilities for storing multiple readings, often with date and time stamps.
