Textile Formaldehyde Content Tester

The Textile Formaldehyde Content Tester is designed to determine formaldehyde content in textile materials and garment fabrics. It uses a water extraction method to prepare the test solution, followed by a colorimetric reaction with Nash reagent. A spectrophotometric measurement system and dedicated software are used to analyze the results.

The instrument features a wavelength range of 190–1,000 nm, selectable spectral bandwidths, and automatic wavelength calibration. It supports standard curve preparation, unknown sample analysis, and direct measurement using stored calibration curve coefficients.

Application

The textile formaldehyde content tester is used to determine formaldehyde content in various textiles and garment fabrics. It employs water extraction method to prepare formaldehyde solution, followed by colorimetric reaction with Nash reagent, and final testing through software analysis.
