QSRED Red Filtered Quantum Sensor
- Compact, fully portable handheld light meter with matched cosine corrected, large area quantum sensor
- LCD digital display of PAR radiation
- Filtered for 550 – 750nm waveband
- 3 measurement ranges (0 – 20, 0 – 200 and 0 – 2000 µmol m-2s-1)
- 0 – 2V analogue output of PAR signal
- Compatible for use with DW3, LD1/2 and LD2/3 electrode chambers as a light source calibration tool
The QSRED quantum sensor consists of a handheld display unit and matched cosine corrected sensor head containing a special high grade photocell filtered for the 550 – 750nm waveband. The linearity of response is excellent with a maximum deviation of 1% up to levels of 3000 watts/m2 (greater than normal solar irradiance).
The μmol m-2 s-1 value from the sensor is displayed on the LCD display. 3 measurement ranges allow maximum sensitivity from 0 – 2000 μmol m-2s-1.
QSRED is intended to be used primarily as a calibration tool for Hansatech Instruments red LED light sources.
