Visible Spectrophotometer, Portable, SP-HVP-A Series
The portable spectrophotometer is compact in appearance and powerful in function. It adopts a 482X272 true color touch screen, and the humanized design is easier to operate. It meets the needs of different customers and is widely used in teaching and daily analysis.
- Luminosity measurement (multi-wavelength test)
Test the absorbance, transmittance and energy of the sample at a certain wavelength, and measure the results at multiple arbitrary wavelengths at the same time.
- Quantitative test
Establish a standard curve for concentration test.
- Time scanning
Measure the change pattern, calculate the reaction rate(SP-HVP-A8L).
- Wavelength scanning(spectral scanning)
Can set the scanning range, interval and speed(SP-HVP-A8S).
- Prefabrication program
Stored programs are pre-programmed methods for reagents, tube tests, and pipette tests.
- User presetsprogram
Users make “measurement analysis” possible: Users can program their own developed methods. Stored methods can be saved as user programs. The test can then be modified to suit the user’s requirements.
