HD903C Mask Formaldehyde Content Tester

• detailed information

Scope of application:

Used to determine the formaldehyde content in various textiles and masks.

Instrument characteristics:

1. Adopting computer control and implementing human-machine dialogue operation, sample reagents, blank reagents and other comparative solutions are put in at once. Through computer data processing, the formaldehyde content F value of the fabric is directly given and the calibration report is printed, simplifying the testing process and minimizing operational errors.

2. The micro processing * T/A conversion technology used can automatically calibrate 0% T.

3. Adopting 1200/mm high-performance gratings, with high wavelength accuracy, good monochromaticity, and low stray light.

4. Imported tungsten lamps are used, which have high luminous efficiency, long lifespan, and low power consumption.

5. It can be calibrated according to standards, automatically analyze discrete errors, and correct the working curve.
