We use an O2 sensitive flurophore system which can do hundreds of leaf discs per day or a differential O2 analyser made by qubit + a licor 7000 for open flow O2 and CO2. A few people in the building use Mims but not super often

Ahh I remember that manual Ali or at least the beard - some people here have used them a fair bit in the past, but we’ve switched to much higher throughput methods for O2 measurements

That’s great, could I also be added thanks!

I guess they kinda sniff leaves! They measure leaf gas exchange, so we can see how much photosynthesis or respiration the leaves are doing.
