HAGNER Evacuation Route Photometer ERP-105
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.
Part No
1) Hagner Model ERP-105 with detector SD17
2) Hagner Model ERP-105 with detector SD27
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.

The spectral sensitivity of the Hagner ERP-105 Digital Photometer closely relates to the visibility
curve of the CIE standard observer.
