Photovac photoionization detection units offer accurate VOC analysis

Photovac, Inc. has announced the addition of the 2020ppbPRO to its family of  enhanced photoionization detection instruments. This new instrument is designed to provide indoor air quality specialists as well as other users with the ability to do low parts per billion (ppb) VOC analysis with exceptional accuracy and precision.

In addition to utilizing the new features recently introduced in Photovac's 2020PROPlus, the 2020ppbPRO is aimed solely at extremely low-level VOC detection. The instrument provides 10ppb precision across its dynamic range of 0 to 40ppm, making it ideal for indoor air quality assessments as well as other hazmat, industrial hygiene, and environmental applications where very low detection levels are required.

Key new features in the 2020ppbPRO include the use of a new 10.6eV high-intensity UV lamp with lamp-quality assessment provided at calibration, display readings in ppm, ppb, or mg/m3, an enhanced compound library, user-defined interval sampling time ranging from 1 to 900 seconds, and an increased alarm sound level of 85 decibels at half a meter. As with Photovac's other instruments, the 2020ppbPRO includes an enhanced eight-line LCD display so that data can be more easily read and analyzed. 

New operating features developed in cooperation with Dräger Safety AG & Co. include the use of activated charcoal tubes to provide accurate “clean air” calibration and humidity reduction tubes to allow more accurate sampling in high humidity environments. Also, compound specific pre-filter tubes are available for single compound sampling, as well as sample collection tubes which allow samples to be taken on site for later review in a laboratory. Use of the Dräger tubes is facilitated by Photovac's new (patent pending) tube holder designed specifically for the 2020ppbPRO.

The 2020ppbPRO is outfitted with a dedicated calibration key for immediate access to the calibration procedure. The keypad features large buttons for quick menu access, even when wearing triple-layer gloves. Additionally, an expanded internal data logging feature allows the operator to record up to 200 hours at one minute intervals.

The instrument is classified intrinsically safe for use in potentially explosive environments in North America and Europe (ATEX).
