ABLE indoor and outdoor light sensors are accurate wall mount lux light level sensors which can be used for monitoring and control applications and are available in measurement ranges up to 20,000 Lux. The built in colour correction filter gives excellent approximation to human eye spectral response and the sensor has excellent linearity and low dark current. The outdoor enclosure is IP67 rated making it ideal for outside use, and the whole range works in -25°C to +70°C temperature / humidity 0% RH to 95% RH conditions. All light sensors come with a 4-20mA output and are individually calibrated to internationally traceable standards by a qualified ABLE technician before delivery is made. Furthermore, batch calibration certificates are available if requested.
