Amperometric oxygen measurement
Typical applications are:
- Pharmaceuticals and biotechnology: process control in enzyme production, control of culture preparations
.
- Water treatment: boiler feed water, WFI (Water for Injection)
- Residual oxygen measurement in processes
Installation
Digital hygienic amperometric oxygen sensor
with maximum measurement stability over several
sterilization cycles available in two measuring ranges
Standard sensor: 0 to 60 mg/l, 0 to 600 %SAT, 0 to 1200 hPa, 0 to 100 Vol%
Trace sensor: 0 to 10 mg/l, 0 to 120 %SAT, 0 to 250 hPa, 0 to 25 Vol%
