Ultra-High Speed Sensors
The well-known high speed sensors of PyroScience are available as high speed (HS, <0.8 sec response time) or now even as ultra-high speed (UHS, <0.3 sec response time).
These sensors were developed specially for measurements of fast oxygen changes in gas or aqueous samples.
Common applications of our high speed sensors:
- Ultra-fast measurements in gas or aqueous samples with response times down to 0.3 sec
- Eddy covariance / correlation measurements of oxygen fluxes
Applicable Oxygen Sensor Types
- Retractable Needle-Type with options -HS or -UHS
- Fixed Needle-Type with options -HS or -UHS
- Bare Fiber Sensors with options -HS or -UHS
