SPECIFICATIONS
The standard customer range is defined as full-scale ranges that fall
within the minimum and maximum allowable for a given Measuring
Cell. Calculations of minimum and maximum are based on atmospheric
pressure.
Methodology
Multiple Wavelength, high resolution, non-dispersive ultraviolet.
