After working several mechanical contractors for two years we took the original Digital Chart Recorder (DCR) and made it even better! The new design includes gasketing for IP67 with lid closed  and a panel mounted battery access.  The exterior pressure connection and viewing window lets you keep the enclosure closed for those days when it's snowing or raining.  The USB port is on the side of the enclosure and can even power up the gauge from the port.  Bluetooth is standard to keep track of things via your phone or tablet within about 40 feet.  If you are looking for even better battery life be sure to check our Lithium Ion rechargable pack, It's a great backup power source as well. Backed with a 4 Year Warranty, just register it..
