Typical Analytical PerformanceNote: exact performances are application dependent and specified at quotation stage. |
| Repeatability | Better than ±1 % of full scale |
| Noise | • Less than ±1 % of full scale at 0.02 absorption units • Less than ±0.5 % of full scale at 0.20 absorption units |
| Nonlinearity | Less than ±2 % of full scale |
Zero sample drift (*) | Less than ±1.0 % of full scale per/day for UV *Zero sample drift over 8hrs is measured at the factory. The zero sample is the simplest mixture representative of the measurement matrix in the absence of the target specie(s).
