DOpO2 is our newest totally integrated optical oxygen sensor. DOpO2 uses our high stability Zero-Drift fluorophores to measure pO2 through dynamic quenching of fluorescence. The DOpO2 sensor is waterproof, includes all electronics, signal processing, calibration coefficients and settings required to calculate and report fluorescence decay (Tau), pO2, O2 concentration and temperature in real time.
The standard DOpO2 uses a USB interface to communicate with full featured Windows based DOpO2 Viewer software. Versions for analog output or RS485 are also available.
The DOpO2 unit is flexible!
You can use it with the supplied sensor cap. The cap screws onto the optical port and holds the sensor substrate disc securely in the optical path. Caps can be changed to use different sensor chemistries (for example for hydrocarbons), or to replace damaged sensors.
Or, you can attach an optical fiber sensor to the optical port. Fiber sensors come in a variety of lengths and styles.
DOpO2 electronics provide more stable signals and at half the cost of our modular versions.
