WPI's TBR Free Radical Analyzer is designed for use with WPI’s wide range of nitric oxide, hydrogen peroxide, hydrogen sulfide and oxygen sensors. The TBR1025 is a single channel version of the TBR4100. Simply plug a sensor into the input channel on the front panel and select the current range. Poise voltage can be selected from a range of values tuned for optimal response from WPI sensors. Real-time detection and measurement of a variety of redox-reactive species is fast and easy with the TBR, which uses the electrochemical (amperometric) detection principle.
