Handheld instruments and loggers can be used for logging, control measurements and single measurements. Odeon is available in two standard models. These can also be set up as a mobile logging unit.
Odeon has optical oxygen sensor. The advantage of optical oxygen sensor is accurate measurements without the need for agitation, in combination with low maintenance needs. A memory capacity of up to 100,000 data points makes it suitable for single measurements and for logging over longer periods.
