The spectral sensitivity of the Hagner ERP-105 Digital Photometer closely relates to the visibility curve of the CIE standard observer.
The Hagner Photometer ERP-105 (Evacuation Route Photometer)
|
The Hagner ERP-105 Digital Photometer is a precision instrument designed to measure the luminance of photoluminescent signs and materials over a range of 0.01-20,000 mcd/m², in the field as well as in the laboratory.
The light sensitive device is a robust silicon photo diode with long-term stability, which with the new patented amplification system is brought to very high sensitivity.
The detector is carefully filtered to produce the same spectral response characteristic as that of the human eye, as defined in CIE-standards.
This remote sensor is supplied with 2 metres of flexible cable. Extension cables can also be used for measurements at any desired distance from the detector.
The instrument has built-in temperature compensation. A "hold" function enables the display value to be retained. A DC-input is provided for battery eliminator, and an analogue output for external instruments such as loggers, computers and recorders.
