    great data logger for the price the only issue we have so far, is that when replacing the battery, the logger needs to be started using the software. This is inconvenient for us as we have deployed these units in our high hygene areas ( we are a food packaging plant) and we need to remove the logger from the floor, take is back to the office, start the logger, then return it to the high hygene floor, resanatize it and then put it back where it belongs. Would be so much simpler if we could just replace the battery while it is on the floor and the unit would automatically restart logging the data.

    Overall its a good unit so we are happy with the purchase, just wish there was a better (automated) way to restart logging data upon battery replacement.
