and calcium hardness (0-1000mg L −1 ) chloride (0-5000mg L −1 ), and sulphate (0-200mg
L −1 ), Comparator 2000 and photometer 5000 versions are available.

De Longe Cuvette and Pipette Tests
These are all based on the use of portable spectrophotometers, the LASA Aqua filter
photometer for small numbers of water analyses, the LPIW filter photometer for water
and sewage analysis and the top-of-the-range Cadas 100 with print-out of results for
water and sewage analysiis (Table 16.3). The latter instrument covers the spectral range
200-900nm among many others.
