Instrument Characteristics

1. The dual beam metering system, combined with advanced circuit measurement and control system, enables the instrument to have high stability and extremely low noise.

2. The newly designed excellent optical system and high-performance holographic dazzling grating ensure low stray light of the instrument, allowing it to operate stably at all wavelengths with four decimal places of absorbance values (two decimal places of transmittance values).

3. The fully automatic control system and advanced design concept ensure that the instrument has high reliability and stability.

4. The sample chamber design with a detachable structure makes it easy to replace different accessories to meet different analysis needs.

5. The spacious open light source room design makes it easier to replace the light source.

6. Imported components are used for key parts to ensure high reliability of instrument performance.

7. The Chinese and English operating software developed in the Windows environment provides rich and unique color analysis functions.

Instrument Functions

1. Luminescence measurement: It can simultaneously measure the transmittance and absorbance at 1-6 wavelengths.

2. Spectral measurement: Scanning spectra of transmittance, absorbance, and energy within the wavelength range, and performing various data processing such as peak valley detection, derivative calculation, and spectral calculation.

3. Quantitative measurement: Regression of 1-9 point working curves (1-4 times) for single wavelength, dual wavelength, triple wavelength, and multi wavelength measurements.

4. Dynamics measurement: Time scanning of transmittance and absorbance at any set wavelength and various data calculations can be performed.

5. Data output: It can access data files and parameter files, and the measurement results are output in a standard and universal data file format.
