PASPORT Colorimeter Sensor - PS-2121

PS2121_inuse_MAIN.jpg

Overview

Our PASPORT Colorimeter records all 4 wavelengths simultaneously--no need to guess at wavelength to get a quality measurement. Digital circuitry handles the calculations, calibrations and adjustments – all you have to do is collect data. Simultaneously reports both absorbance and transmittance. Black, opaque housing eliminates ambient light to assure data accuracy.
Great for Beer's law experiments, absorbance vs. concentrations, and reaction rates.

  • Auto calibration – insert a cuvette of clear water, press one button and calibration for all wavelengths is done.
  • Samples 5 times a second - making rates of reaction experiments a reality.
