Colour Reference and Spectroscopy Standards

Color reference and spectroscopy standards are used to routinely monitor optical spectrometer mechanisms. The calibration solutions provide the base readings that users can compare with the electromagnetic radiation wavelengths and intensities scientific instruments obtain. Placing the reference solution inside, users can zero out settings to reestablish proper mechanics and eliminate systematic error. For quality control, the color reference and spectroscopy standards guarantee that the machines function properly for accurate spectral lines.

ASTM® Colour Standards

Supplier: Merck

The fluid sampling kit is a complete solution for field-based fluid collection and contamination analysis. The stainless steel sampler assembly plugs into a quick-release valve installed in the system line, which allows a measured quantity of liquid to pass through the monitor. A valved syringe serves as a pump to remove residual liquid from the monitor. Kit is compatible with our 37 mm contamination monitors and matched-weight monitors.
