Alphasense will launch its new Electronic Diffusion Tube (EDT) at Pittcon (2019).

The EDT is a single gas monitor which allows users to select from a range of gases at the time of ordering. These include NO2, NO+ O3, H2S, NHand CO, with relative humidity and ambient temperature also being measured.

The instrument is powered up for up to eight months by two replaceable Lithium AA cells. Users are able to set the logging interval from one minute to four hours.

“Diffusion tubes have been the low-cost workhorses of air quality monitoring for decades,” said Arthur Burnley, Alphasense Director.

“However, their main drawbacks have been that they only provide an average reading over several weeks, and results are generally delayed until after laboratory analysis.”

“The EDT resolves both of these issues whilst retaining the advantage of low cost. This is because the EFT contains an electrochemical sensor in a hand-held device that logs readings and transmits data via Bluetooth to a tablet or cell phone running our EDT APP, so this device is ideal for portable survey work or for leaving in locations for extended periods.” Burnley continued.

The product is available in two configurations – as a hand-held unit or in a mounting bracket.

Pittcon will take place between 17th-21st March (2019) at the Pennsylvania Convention Centre in Philadelphia. Alphasense will be at booth 713.
