Fiber Optic Oxygen Meter for Measurements in Normal Oxygen Range

Fibox 3

The Fibox 3 is a proven fiber optic meter for precise oxygen measurements. Due to its small outer dimensions it can easily be set up. Connected to a 2 mm polymer optical fiber this oxygen meter can be applied with various oxygen sensors of type PSt3 (detection limit 15 ppb, 0 – 100 % oxygen). Fibox 3 is a temperature compensated system and delivered with a precision temperature sensor. This way most precise oxygen measurements in environments with changing temperature can be taken. The oxygen meter can be connected to a PC via USB or RS232 interface and is operated with the included software, which allows easy measurement control and data collection. Additionally, the Fibox 3 has dual 12 bit analog outputs, and an external trigger input to be connected to a data logger.
