1 Overview

HD903C formaldehyde content determination by the host computer and software control system composed of two parts.

Quasi-"Determination of formaldehyde in textiles" GB / T2912 · 1 ~ 2912 · 2-1998 Design and production of textile formaldehyde

Quantity of special measuring instruments.

2. Main features

2.1 The use of computer control, the implementation of man-machine dialogue operation, once into the sample reagent, blank reagents, etc.

Than the solution, the data processing through the computer, the fabric directly to the formaldehyde content of F value (mg / kg), automatic

Out of the average of three measured values ​​and print out the test report, simplifying the testing process, the maximum to avoid the

Operation error.

2.2 The use of advanced micro-processing error-free T / A conversion technology, adjustable 0%, 100%.

2.3 with 1200 / mm high-performance grating, high-precision wavelength, monochromatic, low stray light.

2.4 The use of imported tungsten lamp, high luminous efficiency, long life, low power consumption.

2.5 can be corrected according to national standards correction method, automatic analysis of discrete errors, draw and modify the work curve.

3. The main technical indicators

3.1 Determination of formaldehyde content F = 0 ~ 500mg / kg

3.2 Formaldehyde detection wavelength 412 nm

3.3 Detection accuracy ≤ 5%

3.4 Determination based on GB / T2912.1-1998 "Determination of formaldehyde in textiles" Part 1: Free

Hydrolyzed formaldehyde (water extraction)
