Environment for testing:
Based on scanning 1D (Code 128) barcode, under the same lighting condition.
Tested scanning of different barcode sizes until scanner detected good readings.
Distance is then recorded in the above chart for comparison.
Apparently, all 3 scanner models can read the different range of barcode sizes.
Only difference is the distance of reading.
Scanning response about the same, overall quite snappy.
"General Ranking:
(1st = best performance)" Remarks
1st 1950GHD2USBA Generally, best overall
2nd 1900GHD2USBA Almost similar to 1950GHD but required nearer distance to scan
3rd 1950GUD2USBA Good for small size barcodes
