Product Content Description:

The Canneed DER-3 Digital Enamel Rater is the industry
standard. The new DER-3 applied to test the coverage of the
enamel coating inside food and beverage cans. Also
aerosol-cans may be tested with DER-3. It displays an index
of the amount of metal exposed by incomplete enamel
coverage on a clear, easily read digital LED.
The instrument applies a constant voltage across the can
body and an electrode immersed in an electrolyte-filled
can, and measures the resulting current. Test voltage is
set at 6.3 VDC. Operating range is 0 to 300 milliamperes
with accurate resolution within 0.1ma.
The instrument operates in industry standard 4 second mode,
continuously, or can be programmed to measure any desired
time. In 4-second mode, the display shows the reading only
at 4 seconds. In continuous mode the reading is displayed
beside elapsed time with the 4-second reading automatically
stored in memory for recall. A simple and foolproof
calibration self-test verifies correct, accurate operation.
