OS30p+- Hand Held Chlorophyll Fluorometer

Soil & CropsPhotosysnthesis Chlorophyll & Respiration

The OS30p+ provides a graphic color display of both FV/FM protocol measurements & Strasser OJIP protocol measurements. FV/FM is the most used chlorophyll fluorescence measuring protocol in the world and the OS30p+ makes this and Strasser OJIP very affordable, in part, by elimination of an expensive fiber-optic light guide and the introduction of a short, dark clip friendly, optical probe.

Overview

Direct readout and graphic display of FV/FM and FV/FO measurements
Self calibrating red Strasser OJIP light source at 3,500 μmoles - Because Strasser OJIP values change with actinic light intensity. 3,500 μmoles are recommended
Saturation intensities include the standard 3,500 μmoles OJIP intensity, as well as: 3,000 μmols, 525 μmols ,875 μmols, 1,000 μmols, 2,500 μmols, 4,500 μmols, & 6,000 μmols.
Color graphic screen - allows multiple overlayed Strasser color graphs
Direct readout of the most used Strasser protocol parameters including: O, t100, K, J, I, P, tFM, PIABS, Vj, MO, & A
Print out of all of Strasser's measuring parameters in the data file.
Easy modulated light intensity set up with helpful intensity bar.
Affordable dark adaptation clips
USB port - data files and graph data open directly into Excel ®
Housekeeping automation reduces set up time and eliminates some types of measuring errors.
A light bar aides in modulated light intensity set up, using a red modulated light.
Automated 8 point 25ms rolling average to determine maximum FM. This eliminates saturation pulse NPQ as a source of error if the saturation pulse is too long. This feature is only used in the FV/FM protocol.
Automatic light calibration to 3,500 μmols.

Specification

Saturation intensity	600- 6000 μmols set from 10% to 100%
Saturation light source	Array of red LEDs 660 nm
Modulated light source	Red 0.2 to 1.0 μmols.
Detection method	Pulse modulated
Detector and Filter	Pin photodiode with 700-750 nm band pass filter
Test duration	0.1 seconds to 1.5 seconds. The default saturation pulse duration is set at 1.0 second; however, the software takes a rolling eight point 25 ms average to determine FO, and FM, making it idea for both algae and land plants.
Modulated light adjustment	Manual adjustment from 30% to 80%
Parameters measured and graphed	FO, FM, FV/FM, FV/FO
