WEST TUNE Novel Series Spectrophotometer
Novel series spectrophotometer, being combined with an ARM processed core, has test speeds and
functions possessed by high-end instruments. The instrument can meet the requirement of
quantitative analysis for most samples conducted within the visible and ultraviolet-visible spectral
range in conventional laboratories and is suitable for use in medicine and health, clinical examination,
biochemical, petrochemical, environmental protection, quality control departments, colleges and
universities and others.

- Sample compartment for 5-100mm cuvettes
- Equipped with USB port
- Precise automatic T/A changeover
- Internal printer optional
- Automatic zero and full scale adjustment
- Software optional
- Direct concentration read-out and concentration factor setting function
Features
1,7-inch multi color touch-screen and patented technology to achieve simple and effective human-computer
interaction with a clear display of test data.
2,A built- in thermal printer (optional) to achieve printout of test results so as to facilitate the formation
and retention of data reports.
3,A USB communication port and UVWIN8 professional data processing software (optional) to achieve
data processing and mapping functions and storage of massive amounts of data files, and to
facilitate the secondary development by customers.
4,Automatic wavelength setting, fast and accurate.
5,Functions such as wavelength scanning (S model only), kinetic time scanning, automatic wavelength,
linear regression, direct read-out of concentration, peak detection, regular printing and etc.
6,Advanced power shut-down protection measures to memorize detected data, regression equation
and instrument correc- tion parameters to achieve fast initialization.V
7,Tungsten lamp and deuterium lamp (UV model only) with lifetime protection.
