The Zintronix ZI-808 is an intelligent web-based data logger with a built-in web server and internal flash memory. A USB port allows records to be stored there as an option, with the additional ability to store data remotely to any server or email address.

ZI-808 boasts eight differential and isolated analog input channels, programmable as voltage or thermocouple measurement (per channel), along with four pulse input channels programmable as count, frequency, or discrete function (per channel). The unit also offers four real-time discrete alarm output channels with email/text notification.
