OS30p+- Hand Held Chlorophyll Fluorometer
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.
- 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.
| 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 |
