The Textile Formaldehyde Content Tester is a precision instrument designed to determine the formaldehyde levels in textiles, including fabrics and finished garments. It employs chemical extraction and colorimetric methods (e.g., Nessler reagent reaction) to accurately quantify free and hydrolyzed formaldehyde content, ensuring compliance with national and international textile safety standards. The instrument supports high-throughput testing, data storage, and automated wavelength calibration for reliable and repeatable results.
Application
This tester is widely used in:
Textile manufacturing and processing factories for quality control.
Garment production lines to ensure finished products meet formaldehyde safety standards.
Textile laboratories for research and development of safe, low-formaldehyde fabrics.
Inspection and testing agencies verifying compliance with regulatory standards.
Educational institutions for textile chemistry and safety training.
Standards
The instrument is compliant with:
GB/T 2912 – Textiles: Determination of formaldehyde – Part 1: Free and hydrolyzed formaldehyde
AATCC 112 – Textiles: Determination of formaldehyde – Vapor absorption method
BS 6806 – Textile formaldehyde testing
DIN EN ISO 14184-2 – Textiles: Determination of formaldehyde – Part 2: Released formaldehyde (vapor absorption method)
Relevant Chinese national standards: GB 18401-2003. GB/T 23328-2009. GB/T 2664-2009. GB/T 2665-2009. GB/T 2666-2009. GB/T 23314-2009
Features

Test Procedures
(1) Prepare textile sample and extract formaldehyde using water or standard reagent.
(2) React extracted solution with Nessler reagent.
(3) Insert sample solution into the tester cuvette.
(4) Select appropriate test mode (C mode or F mode).
(5) Start the test; instrument measures absorbance and calculates formaldehyde content.
(6) Store results in memory or export via USB/print report.
(7) Repeat for additional textile samples.
Maintenance
Regularly check and replace tungsten and deuterium lamps as needed.
Keep cuvettes and optical path clean to avoid measurement errors.
Calibrate instrument using standard formaldehyde solutions periodically.
Store in a dry, dust-free environment; avoid direct sunlight.
Ensure stable AC power to maintain accuracy and prevent electrical damage.
