The Rex SWC-1 RX Lab Data Analysis Software is invaluable in helping to produce and analyze durometer hardness test data. The RX Lab Software, used in conjunction with the RX Digital Durometer and a PC, allows users to automatically collect, record, and print test data, create statistical information (tolerance, range, mean, variance, standard of deviation), and perform timed tests with a visual graph. The software interfaces with the DD-3 Digital Durometer through the provided RS-232 cable.
