All our Power and Control Systems (Wizard Auto, PILOT Pro, AUTOMAX Pro and Pro-M, AUTOMAX Multitest) can be cost-effectively used to retrofit and update old compression machines to be transformed into a modern automatic compression tester. Any make of testers -fitted with old pressure gauges or old unreliable digital readout units and power pumps with manual flow control- can be easily updated into an automatic system that meets the demands of 21st-century concrete and cement testing.
