Water Formaldehyde Content Detector

The formaldehyde content detector in water utilizes either the acetylacetone spectrophotometric method or electrochemical sensors to react with formaldehyde in water, producing colored compounds or electrical current signals. The formaldehyde concentration is quantified based on absorbance or current values. It is used for testing tap water, wastewater, and water used in food processing to ensure compliance with water quality standards.
