Description

Portable visible spectrophotometer is small in appearance and powerful in function. It adopts true color touch screen and has 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

  1. Photometric measurement: Test the absorbance, transmittance ( SP-HVP-A4) and energy of the sample at a fixed wavelength and measure the results at multiple arbitrary wavelengths at the same time
  2. Quantitative testing: Establish a standard curve for concentration testing ( SP-HVP-A4L)
  3. Pre-programmed programs: Stored programs are pre-programmed methods for reagents, test tube tests and pipette tests.
  4. 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
  5. Frequently Used Procedures: User-selected list of common methods/tests
