Description
The portable visible spectrophotometer is small in appearance and powerful in function. It adopts a true color touch screen and has a humanized design, which makes the operation easier and meets the needs of different customers. It is widely used in teaching and daily analysis.
Luminosity measurement
- Photometric measurement: Test the absorbance, transmittance ( CA-SP-HVP-A4), and energy of the sample at a fixed wavelength and measure the results at multiple arbitrary wavelengths at the same time
- Quantitative testing: Establish a standard curve for concentration testing ( CA-SP-HVP-A4L)
- Pre-programmed programs: Stored programs are pre-programmed methods for reagents, test tube tests and pipette tests.
- User preset programs: User programs make “measurement analysis” possible: Users can program their own developed methods. The stored methods can be saved as user programs. The test can then be modified to suit the user’s requirements
- Frequently Used Procedures: User-selected list of common methods/tests
