PX2

The PX2 Photometer was designed for dynamic sensitivity and ease of use. The PX2 accommodates a combination of measurement methods, light sources, detectors, and several digital and analog communication options to support numerous single or dual wavelength applications. An indicator LED alerts the user to changes in the unit’s operating status. The optional software package allows the user to calibrate for their particular samples.

The PX2 can be packaged for GP, C1D1, or C1D2 electrical area classifications.

Primary applications include:

  1. Chromatography
  2. TFF/Crossflow Filtration
  3. Depth Filtration
  4. Fill & Finish
  5. Oil in Water
