Product Description
Application
range
The TOPAZ Iron is a complete monitoring system for the continuous,
colorimetric online determination of dissolved iron Fe (II+III) in pota
-
ble water, surface water, wastewater and effluents.
Measuring
principle
In a medium buffered to pH 4.6, iron III is reduced to iron II.
Phenanthroline then forms a complex of red color with iron II, which
is detected by the analyzer.
Configurations
The instrument is available in the following configurations:
Measuring ranges:
– TOPAZ Iron LR:
0–100 ppb or 0–1000 ppb
– TOPAZ Iron HR:
0–2 ppm or 0–5 ppm
Available with one, two, four or six measuring channels
(common measuring range)
Signal
outputs
Two signal outputs per measuring channel.
Current loop:
4–20 mA
Relays
Five potential-free contacts per measuring channel with the following
functions:
two thresholds (high/high, low/high or low/low)
sample flow alarm
indication of the active measuring channel
maintenance indication
Maximum load: 1 A/24 V
Alarm relay
One summary alarm for “analyzer failure”.
Maximum load: 1 A/24 V
Digital inputs
One digital input per measuring channel to select the active sample
stream and one digital input to stop measurement.
To use the digital inputs, select control mode 3 (see
).
