YG201D Textile Formaldehyde Tester

[Scope of Application]The determination of formaldehyde content is currently one of the more complex textile testing items, involving fundamental theories of chemical analysis and various basic operational skills. This poses significant difficulty for general test personnel who have not received systematic training in chemical analysis.

[Compliance Standards]

• GB/T 2912.1-2009 Textiles - Determination of formaldehyde - Part 1: Free and hydrolyzed formaldehyde (water extraction method)

• GB/T 18401-2010 National General Safety Technical Code for Textile Products

[Instrument Features]

1. Adopts the national standard method (GB/T 2912.1-2009) and can simultaneously display formaldehyde measurement values and absorbance values.

2. No need to prepare and calibrate formaldehyde standard solutions or plot working curves.

3. Controlled by a microcontroller (MCU) with automatic spectral data processing functions.

4. Uses chemical reagent packs for color development with a long shelf life (1 year). Small sample and reagent volumes reduce and prevent secondary pollution.

5. Features a large-screen Chinese display and human-machine interactive operation. Compact, lightweight, and easy to operate. The main unit has a built-in battery, allowing for portable on-site testing.

[Technical Specifications]

1. Measurement Range: 0.00~500.00 mg/kg (Sample dilution by 10 times allows measurement up to 5000 mg/kg)

2. Measurement Accuracy: ≤5%

3. Measurement Method: National Standard Acetylacetone Method (GB/T 2912.1-2009)

4. Light Source: Ultra-high brightness LED, Wavelength 412nm

5. Operating Temperature: 5~40℃

6. Main Unit Weight: 2kg

[Test Principle]Accurately weighed textile specimens are extracted in a 40℃ water bath for a specific time. The formaldehyde extracted from the fabric is absorbed by water. The extract is then developed with acetylacetone (turning yellow). Since this yellow compound has selective absorption of visible light, a colorimetric analysis method is used to measure the formaldehyde content in the test specimen using the textile formaldehyde tester.
