MicroTip - Fiber Optic Oxygen Sensor

Options

501656 - MicroTip, needle-type housing fiber-optic oxygen sensor, 50 μm tip

501656-C - MicroTip, needle-type housing, 50 μm tip, optical isolation

501656-F - MicroTip, needle-type housing, 140 μm flat tip

The MicroTip is a needle-type (27 ga.) oxygen microsensor created for applications requiring a 50 µm tip size and a 1 s t90 response time. The 140 mm fiber that makes up the oxygen-sensitive sensor tip is trimmed to a 50 µm tip. A stainless steel needle with a diameter of 0.4 mm and a length of 22 mm contains the sensor. This makes it possible to pass through rubber septums or other similar materials. These sensors are perfect for determining the oxygen content of sediments and biofilms.

• This sensor, 501656-C, has an optical isolation coating. The optical isolation is an optional, opaque, oxygen-permeable coating that can be applied over the luminophore to stop ambient light from entering the sensor and excitation light from departing. Due to the additional layer of material that oxygen must pass through in order to reach the luminophore, this coating extends the response time.
• The sensor 501656-F has a 140 μm flat tip.
