What is the Future for SmartCure?
Increase practicality for the field:WirelessHand-heldIncorporated onto the cure cart by the manufacturer
What is the Future for SmartCure?
Conclusion
SmartCure helps contractors ensure that they are getting a good cure – can it keep from replacing slabs??SmartCure logs info on temperature and production – info that can optimize operation??SmartCure records weather info by station – can it explain “problem” areas if they occur??Additional adjustments planned: wireless version, text messaging, more visual interface
Any questions?
