Residual analyzer is an analyzer, which is designed to continuously monitor free or total chlorine or other oxidants in drinking water, wastewater, cooling water and other process water applications. It has a unique 3-electrode measuring cell arrangement that enables it to measure in the parts per billion residual range, as well as high residual ranges to 60 mg/l. These are microprocessor-based and feature a large, dot matrix graphic display, on-screen instruction and automatic ranging.

Residual chlorine monitor continuously measures total residual chlorine by means of a direct sensing polarographic sensor. The sensor electrodes are isolated from the sample by a chlorine permeable polymeric membrane. The main applications for this instrument are for the measurement of free available chlorine concentration in feed water at filtration plants, pumping stations and end-of-pipe distribution points.

Residual gas analyzer systems are used to control the pressure of the beamline vacuum system. It is used to detect leaks in beryllium windows terminating the beamline as well as searching for hydrocarbons to avoid mirror contamination. It runs automatic and is accessible via the local ethernet. A server program allows permanent registration of selected partial pressures. It allows observing the temporal partial pressure development over an extended time period.
