TrackSense Pro XL Wireless Data Logger - Bowie Dick Sensor

TrackSense Pro XL Wireless Data Logger - Bowie Dick Sensor

This highly compact Bowie Dick Sensor is the only electronic test device on the market designed for 121 °C processes - and, when necessary, 134 °C. The sensor provides far more insight into critical sterilization parameters than previously possible, making it a critical tool for any steam penetration study.

Unlike traditional chemical indicators, where you subjectively decide according to a change in color, this device provides you with an accurate report that eliminates any guess work.

The device is extremely easy to use and requires little to no training. With just a single click in the software, the unit will start to measure and record data. Once the Bowie Dick Test Program is done, the device is simply placed back in the reader station where the software automatically processes the data and provides a test result – simple and easy!
