Pigment Meter
Multiple wavelength pigment meter
Field portable pigment meter using optical transmittance and fluorescence to characterize intact leaves. Five narrow band light sources are independently controlled for precise and repeatable readings. Three are used exclusively to excite fluorescence, the remaining two are for transmittance. Calculations can be modified for custom parameter measurements.
The MPM-100 is a field portable pigment measuring instrument. It can be used on any thin, flat material to measure both optical transmittance and fluorescence characteristics. The sample measuring area is 9.5mm in diameter. The top measuring head contains five light sources and a filtered detector. Three of the sources are dedicated to fluorescence excitation and two are for transmittance. The bottom measuring head contains a broadband detector for transmittance measurements. The detector filter is set for the target fluorophore.
User defined formulas calculate final values. This allows for custom tests to be developed and implemented. The instrument includes a high performance data logger, 3.2″ touch sensitive color LCD screen, USB connectivity, built in GPS receiver, and internal data storage.
When a test is started, three source LEDs are flashed and the resulting fluorescence is recorded from the top sample head. Flashes of light are very brief to minimize any effect on the sample. Transmittance measurements are then made by flashing the two remaining LEDs and recording the signal present on the bottom sample head.
Fluorescence LEDs and detector are factory calibrated for a normalized response. Relative changes between fluorescence channels are minimized because the fluorescence is excited and detected on the same side of the sample resulting in no movement between the sources and detector.

70 Amp-hour battery belt
This belt is designed to provide a source of power for Opti-Sciences OS5p+ and OS1p fluorometers, used at remote field sites, when recharging is problematic. Scientists also use them for extreme weather conditions. Battery charge life can be significantly reduced under extreme heat or extreme cold conditions.
Articulated locking arm
This is a tripod like accessory that allow PAR clips, The Y(II) meter, or the iFL measuring chamber to be adjusted and locked at various locations, and angles for laboratory measurement. Angles and locations can be quickly set and locked in position with a single adjustment knob.
Instrumentation not included.
Dark adaptation clip
Dark adaption clips are designed to provide an affordable yet reliable measuring solution for large populations of plants. Some Scientists buy hundreds of dark clips. The clips are built with sturdy and weather resistant yet cost effective materials. Flexible gaskets automatically seal the sample area from any light. An easy to operate slider is built-in to expose the sample surface after dark adapting.

PAR Clip
Opti-Sciences digital PAR clip provides both Photosynthetic Area Radiation measurements and highly accurate leaf temperature using modern thermistor technology accurate to ± 0.5oC. Its bottom opening design allows for a more convenient one-handed operation.
Tripod with articulated arm
This is a large universal tripod that also includes the FL-ARM stand. It can be used for trees or other larger plants. At the top of the tripod is an articulating arm that allows the PAR clip to be adjusted to almost any angle or position. The articulating arm may also be used with a base plate that comes with the FL-T stand, for use in the laboratory, on smaller plants.
