The Thermo Scientific ADR1500 utilizes the highly sensitive light-scattering photometer technology (nephelometry), as used in the Thermo Scientific pDR Series, and incorporates a temperature and relative humidity (RH) sensor coupled with an internal heater to mitigate the positive bias with elevated ambient RH. Additionally, the flow control is truly volumetric and is maintained through digital feedback of the onboard barometric pressure sensor, temperature sensor, and calibrated differential pressure across a precision orifice. The principles of true volumetric flow, as incorporated by the ADR-1500, result in an unbiased continuous measurement reading of the concentration.
