The fiber-optic temperature sensors rely on thermal quenching of photoluminescence and are optimized for the innovative REDFLASH technology from PyroScience. The optical temperature sensors are characterized by extreme photo-stability, small size of the sensor tip (minisensors), ultra-fast response times (<0.1 s in water), and do not show interferences with gases (such as oxygen) and ionic species.

This fiber-optic minisensor consist of an optical fiber with a sensor tip diameter of 430 µm. Compared to a microsensor, this sensor is suited for slightly larger samples, long-term measurements and profiling applications with less spatial resolution requirements.

Temperature range. This sensor is specified for the range of 0 to 50°C. Measurements at higher temperatures are possible, but the sensor specifications are not valid for temperatures out of this range.

Fixed fiber. The fragile sensor tip protrudes ca. 2mm from a straight-cut needle. They can be applied in liquids and in gases. The complete inner space of the syringe needle is carefully filled with glue, minimizing any gas reservoir which might slow down the response time of the sensor.

Ultra-high speed. Our fiber-optic temperature sensors offer a very fast response time (t90) of < 0.1s in water.

Optical isolation. For applications at high ambient light (e.g. direct sunlight, illuminated samples) and in fluorescing / light-sensitive samples, an additional optical isolation (-OI) protection layer is added to the sensor surface to reduce enhanced sensor aging and to avoid interference with the oxygen measurements

ST-connector. This connector is our standard sensor connector for sensor compatible PC-operated and handheld FireSting devices.

Specialized for gas. This sensor is specifically designed for measurements in gases. The cannula is filled with glue, to prohibit any gas transfer and any pollution of the sample through unwanted gas transfer through the cannula.

Star sensor. This sensor is one of the world's best or only solutions in a certain application area, featuring for example a very fast response time, solvent resistance or a unique sensor format.
