2020PROPlus photoionization detector

The first of a new family of enhanced photoionization detection instruments, the 2020PROPlus boasts an extended dynamic range, several new operating features and an enhanced user interface. The dynamic range for the 2020PROPlus has been extended to 10,000 ppm with, 0.1-ppm precision to 100 ppm and 1-ppm precision up to 10,000 ppm. New operating features include the optional use of activated charcoal tubes to provide more accurate “clean air” calibration, and humidity reduction tubes, which allow more accurate sampling in high humidity environments. Also, sample collection tubes are available that allow samples to be taken on-site for later review in a laboratory. New user interface features for the 2020PROPlus include instant-on operation, lamp quality assessment provided at calibration, display readings in ppm, ppb or mg/m3, an enhanced compound library, a user-defined interval sampling time ranging from 1 to 900 s, and an increased alarm sound level of 85 dB at half a meter.
