Measure multiple species simultaneously

The TBR is designed for use with WPI’s wide range of nitric oxide, hydrogen peroxide, hydrogen sulfide and oxygen sensors. The TBR4100 can measure four different species simultaneously in the same preparation. 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. An independent output for real-time monitoring of temperature is also included.

Lab-Trax data acquisition system is flexible

The TBR1025 analyzer utilizes PC-based data acquisition via our Lab-Trax interface. Data traces are displayed and recorded in real-time. The LabScribe software (formerly called DataTrax) comes pre-configured for single or multiple electrode recording; filters, gains, and smoothing are all set for optimal results. Data can be viewed making adjustments to smoothing and filter settings without affecting the original stored raw data. Electrode calibration from multiple concentration readings can be input into the software's Multipoint Calibration utility quickly provides a plot and slope calculation for electrode sensitivity determination.

Alternately, the Lab-Trax data interface can be used for providing simultaneous acquisition of Free Radical data along with other physiological data (ECG, HR, BP, etc.) as each of the four input channels has its own independent input, filters and 24-bit converter.
