The E-SAMPLER is rugged, highly portable and easy to use. The all aluminum enclosure is not only rugged but provides electronic stability by filtering potential RF interference. Set-up is a snap with the quick connect system used with the EX-905 tripod. For other mounting applications, holes are provided to fasten to any structure. Simply turning the monitor on will start sampling using the most recent parameters. The unit will continue to operate until user intervention or battery failure. Auto-Zero and Auto-Span ensure that the data collected will be of the highest quality. Both Zero and Span can be operated manually or individually programmed at varying time bases (15 minutes to 24 hours). The E-SAMPLER can also be configured for start/stop times, recording periods, averaging time and other parameters.
