Complete monitoring system for the automatic, continuous measurement of trace
amounts of silica in ultra pure water.
Monitor AMI Silitrace Ultra
 Measuring range: 5 ppt (0,005 ppb) to 25 ppb
 Based on colorimetric measurement principle.
 Programmable automatic calibration.
 Programmable automatic verification.
 Programmable automatic blank determination
(Permeat).
 Manual Zero measurement.
 Complete system including measurement and
control electronics, photometer with integrated
constant-temperature reaction chamber, flow indicator, reagent dosing system and reagent containers using reversed osmosis system to concentrate the sample (Carrcentrator).
 Continuous, automatic monitoring of main instrument functions (sample flow, reagent supply,
reaction
temperature
and
pump
tube
integrity).
 Measurement values are available as analog
output signals.
 Alarm display and activation of alarm relay when
user defined, critical limits are reached.
 Large back-lit LCD display showing all measured
values and status information simultaneously.
 Easy user menus in English, German, French
and Spanish. Simple programming of all parameters by keypad.
 Data logger for 1’500 data records stored at a
selectable interval.
 Factory tested, ready for installation and operation.
