Measures illuminance (Lux, footcandle) in the field, meeting CIE photopic spectral response and is fully cosine-corrected for the angular incidence of light. Supplied with software, USB cable, carry case and battery.

Measures illuminance (Lux, footcandle) in the field, meeting CIE photopic spectral response and is fully cosine-corrected for the angular incidence of light.

The HT-1309 digital illuminance meter is a precision instrument and is compact, tough and easy to handle.

The light sensitive component is a very stable, long-life silicon photo diode and spectral response filter.

Supplied with Windows compatible software for transferring data to a computer, removable rubber protective holster (including tilt stand), USB cable, carry case and 9V battery.
