24-Channel Reader for Online O2 & pH Monitoring in 6- and 24-Well Plates
SDR SensorDish® Reader Extension Set
Up to 9 SDR Extension Sets can be combined with one Basic Set. The Extension Set consists of a reader and a connection cable to install up to 10 devices in a row. Instead of having to change the plate on the reader monitoring can be carried out in up to 240 samples in parallel. The up to 9 Extension Sets and the Basic Set SDR can be controlled and read out with one software.
- Optional extension for parallel monitoring of up to 240 samples
- Parallel online monitoring in disposable 24- or 6-well plates
- Deep well plates (24-well format) & low well plates available
- Non-invasive & non-destructive measurement
- Pre-calibrated
- For use in incubators and on shakers

FAQs
Are there some general recommendations for measurements with the SDR?
Can I use a different measurement interval for each connected SDR?
How do I fix the SDR on a shaker?
I forgot to change the oxygen unit in the SDR software from the default unit "air saturation" to my preferred unit. How do I get my preferred oxygen unit?
I have more than one SDR connected. Can I choose which SDRs I want to use for measurement?
Is the temperature which I see in the maintenance window of the SDR software used for temperature compensation?
The SDR software says 'No SDR found'. What can I do?
What air pressure value should I enter in the SDR software? Where do I get it from?
What happens if I cross the 30 °C-line during measurement with the SDR?
What is salinity? What value should I enter in the SDR software?
What is the difference between the 2 black masks for the SDR, the SDR-OSM24 and SDR-MSV24?
What is the time of delivery?
Which measurement interval should I use for measurements with the SDR?
Why can't I see running and uploaded measurements simultaneously in the SDR software?
Why can't I upload a previous measurement in the SDR software?
Why does the SDR software show pH<5, although I know that my sample is basic?
