For the investigation of plant physiology, ADC produces the most portable and user-friendly equipment on the market. The photosynthesis measurement systems – ranging from ultra-compact to sophisticated systems for comprehensive experiments – are invaluable tools for thousands of researchers worldwide. To accurately and non-destructively measure leaf area and associated parameters, ADC produces the most compact and portable commercially available device. ADC’s hand-held Chlorophyll Content Meter is a highly reliable and affordable instrument to non-destructively quantify chlorophyll. To allow plant stress to be investigated through chlorophyll fluorescence, ADC supplies a range of chlorophyll fluorometers – from compact hand-held devices to fluorometers that offer exceptional experimental control and more testing protocols than any other portable fluorometer.
