Formaldehyde Tester for Textiles
Use
It is used to test formaldehyde content in various fabrics.
Features
1.Microcomputer control, automatic data processing functions with the spectrum.
2.With the measurement of absorption curve, the selected wavelength, absorbance and transmittance parameters etc.
3.Chemical reagent package color (yellow), use less sample and reagent can reduce and prevent secondary pollution.
4.Real-time display ambient temperature,it can set the color of time, automatic measurement and display the measured values and the absorbance values of formaldehyde.
5.The size is small,as well as a light weight, with man-machine interaction,so as to operate simply

What are the qualitative test for formaldehyde?
A qualitative analysis for formaldehyde identification is based on the formation of a purple colored complex. The quantitative analysis was performed by spectrophotometry. The qualitative and quantitative formaldehyde analysis methods were applied to 13 bottles of hair straighteners.
