Dear all,

I need your kind suggestion in regards to temperature monitoring.
Normally we use min/max thermometer for daily monitoring of temperature. Also we use data loggers as back up device, as we know sometime thermometer may show some deviations due to battery fault or any other faults.

Recently I have been told by sponsor that we only allowed to use one device either data logger or min/max thermometer. To what extent you will comfortable with this comment.
