Can any one suggest me how to measure temperature of growth incubator using licor photometer/radiometer ...how to measure light intensity and how to convert microeinstein to micro mole? ...what is best light intensity for growing arabidopsis in soil?
The unit should be written as: μmol·m-2·s-1
Most horticultural researchers measure instantaneous light in micromoles (μmol) per square meter (m-2) per second (s-1), or: μmol·m-2·s-1 of PAR. See attached article.
According to this PDF document from Arabidopsis Biological Resource Center (ABRC), they suggest the optimum light intensity for Arabidopsis is 120-150 μmol·m-2·s-1.See attachment, yellow highlights at page 4, 'Light' section of 'growth conditions' paragraph.
Please see the link below for (1) measurement of light, and (2) some conversions between units.

MEASUREMENT OF LIGHT (LIGHT INTENSITY):
1. Radiometric Measurement
-Measurement of light energy
-Units: Joules, calories, watts (watt m-2)
1 Joule = 0.24 cal
1 watt = Joule . s-1
2. Photometric Measurement
-Measurement of brightness
-Units: foot candle, lux, µmol m-2 s-1 (PPF, Photosynthetic photon flux)
