OS5p+ - Offering the most advanced portable modulated measuring solutions available.
A built-in stable actinic light source, and an FM correction option, using a single multiple-phased saturation flash, move the OS5p+ to the head of the class. The instrument provides a color graphic display for all measuring protocols. While it includes the standard dark and light adapted FV/FM, FV/FO, Y(II) or (ΔF/FM), ETR, PAR, and leaf temperature protocols, it also offers enhanced new solutions in other areas. The combination of a built in stable actinic light source and comprehensive quenching protocols make this system and the OS1p, uniquely capable of reliable field and lab quenching measurements. Quenching protocols include: Kramer lake model, Hendrickson lake model with NPQ, puddle model, and quenching relaxation protocols with qE, qT, and qI. A new Vredenberg OJIP quenching protocols is provided along with an advanced Strasser OJIP plant stress measuring protocol. This latest model also includes a Rapid Light Curve protocol with on board curve fitting. The PAR Clip comes as a standard part of this package.

OS1p - Modulated fluorometer - Ideal for most plant stress measuring applications.
Designed for highly portable advanced plant stress testing. This instrument offers both light and dark adapted protocols for almost all plant stress measuring needs. It provides a color graphic display of FV/FM, FV/FO, Y(II) or quantum yield of PSII (ΔF/FM), ETR, PAR, and Leaf temperature along with a graph of the measuring trace. A version is also available that provides Rapid Light Curves with onboard curve fitting software, and quenching protocol with NPQ. The FM correction option is also included with the OS1p. PAR clip optional.

OS30p+ Hand held Portable Modulated Chlorophyll Fluorometer.
A hand-held research grade modulated chlorophyll fluorometer with color graphic display and direct read out of the dark adapted FV/FM,
FV/FO, and advanced OJIP parameters. Advanced Strasser protocol OJIP parameters such as PIABS, MO, Vj, Area, and others, are displayed along with fluorescence traces on the instrument color screen. Traces and all of the Strasser protocol parameters are also recorded in a data file, and may be output by USB port for future analysis. The data file allows easy creation of overlaid OJIP traces, and spider graphs of parameters.

CCM-200 plus - Portable Chlorophyll Content Meter.
ACM-200 plus - Portable Anthocyanin Content Meter.
Non-destructive in-situ measurements of Chlorophyll content or Anthocyanin content. An easy to use, fast and reliable instrument with a large memory to store up to 160,000 measurements. Both versions offer selections for single measurement, averaging from 2 - 30 measurements, and averaging with outlier removal greater than 2 sigma. Both instruments integrate a larger measuring area for greater absorbance measuring reliability. The CCM-200 plus is excellent for nitrogen management studies.

CCM-300 - Portable Chlorophyll Content Meter for Small and Difficult to Measure Samples.
This is a unique instrument that follows a proven non-destructive technique. Until now, this technology has been too expensive for most applications; however, the new CCM-300 is very affordable. It will measure samples that can not be measured reliably by other instruments. It provides direct readout in chlorophyll content and may also be used on larger leaves such as maize, wheat and maple leaves. Now, plants may be measured from germination through maturity. Applications include: Conifer needles, rice, turf grass, cactus, fruit, Arabidopsis, lichens, algae on rocks, leaf stems, petioles, or even recently germinated Arabidopsis leaves.

GFPIII - General Fluorescence Probe.
This is a very flexible instrument with field interchangeable fluorescence filters. It is designed for a variety of applications including the testing for genetically modified organisms in gene expression studies. Filter combinations are available for GFP (Green fluorescent protein), YFP, Fluorescein, Rhodamine and other fluorochromes. Sensitivity is in the ppb range for most applications.
