Product Details

The X57/PAR-1 (M) miniature probe is
extremely compact in size making it an
ideal choice for leaf cuvette or canopy
measurements where size is of great
importance. A separate sensor conditioning unit (PAR-1 E) is available for use with
the X57/PAR-1 (M) and can be situated at a
site remotely from the actual sensor

Probe Construction Anodized aluminium
PAR Sensor Silicon photodiode

Diffuser Acrylic material selected for neutral absorption in the visible range and short wavelength

Optical glass absorption filter and near infrared cut-off interference filter
