My humidor has 3 hygrometers one analog and 2 digital. I have salt tested all three and they read 75% but my analog inside my humidor fluctuates from 63 to 68 the digitals read 66 and 65 almost constantly and I humidify with beads and use a small fan to circulate the air. Unless you are really set on 70% I would suggest lowering your RH to 65 to 67 and getting a digital hygrometer.
