This is a Hach DR/100 colorimeter, a portable water analysis system used to measure the concentration of specific substances in a liquid based on color changes.
Description of the content:
1. Hach DR/100 Colorimeter (the gray/blue unit in the bag)
• A portable and battery-powered instrument for chemical analysis of water quality.
• Often used to measure chlorine, ammonium, iron, phosphate and other parameters in water samples.
2. Glass cuvettes and reagents (in the compartments above the device)
• Small glass containers where samples are mixed with reagents to create color reactions.
• The color intensity is then measured by the colorimeter.
3. Accessories and syringes (on the right in the bag)
• Used to accurately measure and dose liquids into cuvettes.
4. Manual: “DR/100 Colorimeter Manual”
• A detailed instruction manual on how to use the device and interpret the measurement results.
Possible uses:
• Water purification & analysis:
• Used by water utilities and laboratories to measure water quality and track contaminants.
• Environmental and field surveys:
• Perfect for quick field tests, such as at lakes, rivers or sewage analyses.
• Food and beverage industry:
• Control of water use in food and beverage production.
• Chemistry and laboratory analyses:
• Used in research environments to analyze chemical solutions.
Summary:
This Hach DR/100 Colorimeter is a portable water analysis instrument, often used for color reaction-based chemical tests of chlorine, ammonia, and other substances in water. It is useful for field measurements and laboratory work where accurate water quality is essential.
