- Biospherical Instruments' Quantum Scalar Laboratory sensors make it possible to accurately measure PAR in aquatic or dry environments. The QSL is available in either analog (QSL-2200) or digital (QSL-2100) output models. The electronics are miniaturized to fit entirely in the handle of the light pipe and the entire sensor is submersible to 1 m depth for 30 s.
- The small size and convenient hand wand ensures that Biospherical Instruments’ QSL scalar sensors provide accurate light measurements from virtually all directions in the field or in the laboratory. The long light pipe is particularly convenient when used in growth chambers for organisms such as photosynthetic bacteria, plankton, kelp, and higher plants. The 1.27 cm diameter collector on the QSL-2100 or the QSL-2200 is specifically designed for insertion in vials of the type commonly used in photosynthetrons.
