Item Description
This listing is for a PreSens Fibox 3 LCD trace oxygen meter (version 7) — a bench-top fiber-optic oxygen measurement system with an integrated LCD display and data logging, designed for highly sensitive dissolved and gaseous oxygen measurements. It pairs with optical sensors based on a 2 mm polymer fiber such as the included PSt3 dipping probe (normal oxygen range with ~15 ppb detection limit). 
The meter features both USB and RS232 (serial) connectivity for PC control, data export, and integration with data-acquisition systems, and ships with the required software and interface cable.
