Overview

Visible spectrophotometer (transparency tester) Product model: XD-41-721 Brand name: Modern Environment Product origin: Shanghai Purchase heat: 9626 Relevant standards: GB/T 1721 XD-42-721 Visible spectrophotometer can qualitatively and quantitatively analyze sample substances in the near ultraviolet and visible spectral regions.

Product Details

1、 Purpose:

The XD-41-721 visible spectrophotometer (transparency meter) can perform qualitative and quantitative analysis of sample substances in the near ultraviolet and visible spectral regions. This instrument is a newly developed product to comply with the implementation of the "Implementation Rules for the Production License of Hazardous Chemical Coatings". This instrument is designed and manufactured according to GB/T 1721 "Determination of Appearance and Transparency of Varnishes, Oils, and Diluents". It does not require any standard reagents, is very simple and convenient to use, and quantifies the level of product transparency, effectively improving the current testing accuracy problem of this national standard.

2、 The working environment of the instrument:

2.1 The instrument should be placed in a dry room with a temperature range of 5 ℃ to 35 ℃ and a relative humidity not exceeding 85%.
2.2 When in use, place it on a sturdy and stable workbench, and avoid strong or continuous vibrations.
2.3 Indoor lighting should not be too strong, and direct sunlight should be avoided.
2.4 The electric fan should not blow directly onto the instrument to avoid affecting its normal use.
2.5 Try to stay away from high-intensity magnetic fields, electric fields, and electrical equipment that generate high-frequency waves.
2.6 The power supply voltage for the instrument is AC220V 220V, with a frequency of 50Hz 1Hz, and must be equipped with a good grounding wire. It is recommended to use an AC stabilized power supply to enhance the anti-interference performance of the instrument. Use electronic AC voltage regulators or AC constant voltage regulators with a power of over 1000W.
2.7 Avoid using in places with corrosive gases such as hydrogen sulfide and fluoride sulfite.
