HAGNER DIGITAL LUXMETER EC1-X
The EC1-X has been designed for measurement of illuminance levels in places where it is important
that the operator does not shade the detector. The EC1-X has the detector connected with a 2 meter
long cable. An extension cable can also be connected.
Specification

Weight : 0.19 Kg (EC1-X 0.48 Kg with carrying case)
Part No
1) Hagner Digital Lux Meter Model EC1-X
Operation
The EC1-X is used exactly as the EC1. The detector can be connected or disconnected without
causing any damage to the instrument. Care should be taken to ensure that the cable is not twisted
when replacing the cable. It is recommended that the detector is rotated rather than winding the
cable around the detector.
Please Note
The detector is individually calibrated to the respective instrument and can not be interchanged with
other detectors. Check carefully that the instrument number in the cover corresponds with the
number of the detector.
Instrument Data for EC1-X
The Hagner Photometer, model EC1-X, can be made in several variants in the respect of sensitivity
and spectral response. For instance:
EC1 UV-A ultra violet 315 – 380 NM. EC1 IR infra-red 700-1150 NM.
The spectral sensitivity of the Hagner luxmeter closely relates to the visibility curve of the CIE
standard observer.
The cosine correction compensates for measuring errors owing to oblique incident light.
