Extech HD450 Heavy Duty Light Meter Datalogger

The Extech HD450 Light Meter & Datalogger offers a wide measurement range up to 400,000 lux (40,000Fc) with cosine and colour corrected measurements. The Extech HD450 light meter features an accurate silicon photo diode and spectral response filter to offer the high precision lux light level readings. The data logging function of the HD 450 lux meter allows the device to automatically store up to 16,000 readings or to manually store and recall up to 99 readings. This high precision illumination meter from Extech is perfect for measuring and recording illumination in domestic, public and industrial buildings and can be used to greatly reduce the amount of energy wasted in a building by significantly increasing the efficiency of the luminaries in the lighting system. The heavy duty, double moulded housing of the Extech 450 light meter makes it suitable for a wide range of applications in tough environments and the USB port located on the instrument allows for test results to be downloaded on to a PC and analysed using the provided Windows compatible software.
