RaySafe X2 Light Sensor
The RaySafe X2 light sensor has an excellent photopic response, and an ergonomic and durable aluminum design, which allows for both manual measurements as well as easy mounting for automatic measurements.
A small aperture angle ensures compliance with international regulations. For added ease-of-use, an acquisition key is available on both the sensor and in the base unit interface.
By turning the aperture wheel on the X2 light sensor it can be used for both luminance and illuminance measurements. With a third mode you can select the sensor automatically makes a zero adjust. This is recommended when performing very low luminance measurements.
