Hagner Digital Radiometer EC1-X UV-A

Hagner Digital Radiometer EC1-X UV-A

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

The Hagner Digital Radiometer, model EC1 UV-A, is a small, handy and extremely easy-to-use
instrument for accurate measurement of radiation over a range of 0.001-2,000 W/m 2 with both
automatic zeroing and on/off switch, the only controls needed are a four-position range selection
switch and a hold button for retaining the display value

Operation

The EC1-X UV-A is used exactly as the EC1 UV-A. 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.

To open the lid, press the forward part lightly downward with your thumb and at the same time pull
the latch upwards with the first two fingers of the same hand. The Radiometer comes on when the
cover is opened and turns off when it is closed. Move the range switch to the range which will give
the greatest accuracy and read the display. The hold function keeps the reading on the display until
the hold button is released. Full instructions can be found on the inside of the cover.

Maintenance

The power source is a standard 9 Volt battery. To avoid battery leakage only alkaline batteries
should be used. When LOBAT appears on the display, it is time to replace the battery. However, the
Radiometer can be used for approximately 20 hours longer before replacing is necessary.
Change the battery by removing the screw at the front edge of the cover plate, which permits the
plate to be lifted up and removed. When replacing it the lower edge of the plate must fit under the
two bosses at the lower edge of the case before it can be closed again. The white plastic disc over
the detector may be cleaned when necessary with a light damp cloth.

Calibration

The Radiometer is carefully calibrated when it is delivered. Intervals of recalibration may be 1-3
years, depending on the intensity of the radiation to which the detector is exposed, time intervals of
exposure and the general environment in which the instrument is used.
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 on the detector.
