Description

Product Features:

·Dual beam metering system, combined with advanced circuit measurement and control systems, makes the instrument highly stable and extremely low noise.

·The newly designed excellent optical system and high-performance holographic flash grating ensure the low stray light of the instrument, allowing the instrument to operate stably at the full wavelength in four decimal places after the absorbance value (2 decimal places after the transmittance value).

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

·Photometric measurement: The transmittance and absorbance at 1 to 6 wavelengths can be measured simultaneously.

·Spectroscopic measurement: Scan the transmittance, absorbance and energy in the wavelength range, and various data processing can be carried out such as peak and valley detection, derivative operation, graph operation, etc.

·Quantitative measurement: single-wavelength, double-wavelength, three-wavelength and multi-wavelength measurement of 1~9 working curve (1~4 times) regression.

·Kinetic measurement: Time scanning of transmittance and absorbance at any set wavelength and various data operations can be performed.

·Data output: Data files and parameter files can be accessed, and the measurement results can be output in a standard common data file format.
