wall-mounted housing. Proven sensors offer low limits of detection and exceptional accuracy. For example, the CO2 +/-3% of reading above that up to 10,000ppm for CO2


II probes will now connect via Bluetooth LE wireless to Apple and Android devices. These highly reliable, adaptable DSII probes for indoor air quality (IAQ) and toxic gas testing/monitoring


will imminently have Apps for iOS and Android operating systems available, free of charge, on the Apple and Google App stores. Operators can now use their smartphones or tablets as a multi-parameter display, data-logger and far more. You can choose from over 25 highly accurate, smart indoor air quality, green building, industrial hygiene, and HVAC sensors including TVOCs (PID), carbon dioxide (NDIR), ozone (electrochemical), CO, NO2


smartboards would not introduce noise or degrade accuracy, stability, or limits of detection (LODs) for the convenience of end-user swappable sensors.


Store “snapshot” logs during walk-throughs or set up logging over time at the interval of your choice on the smartphone. Display up to 8 real-time readings simultaneously or show trend graphs on your screen. When derived readings, such as dewpoint temperature, are displayed/logged or if large fonts are chosen, scroll the display to view additional parameters. Feature-rich, the smartphones can add photos, videos, text, audio notes and more directly to data fi les for effi cient, reliable documentation. On-board educational information will be added soon, such as help videos, sensor, and feature tips. Easily e-mail logged data, with all notes attached, and use GrayWolf’s WolfSense®


and custom report template creation. The same DirectSense II probes can additionally interface to alternative platforms to simultaneously support parameters such as high accuracy particulates, differential pressure and air velocity. Easily switch from using your smartphone to using GrayWolf’s AdvancedSense®


The DirectSense II probes are easily handheld or clipped to a belt, come with a charging stand for convenient desktop trend-logging and include a wall-mounting bracket for continuous monitoring applications. A built-in fan actively draws air across sensors.

industrial locations GDS Technologies recently launched the GasVac®


For More Info, email: email:


Solo single line gas sample unit,


which offers an effi cient and precise method of monitoring gases continuously in restrictive harsh industrial environments where standard gas sampling instruments are not enough.


In a recent project, the GasVac® Solo was


deployed by a biotechnology company who specialises in food waste recycling. Other methods of gas monitoring had been tried, but none had worked because of the high humidity levels affecting the instrumentation’s performance, until the GasVac®


Solo was


installed and solved the problem. The GasVac®


Solo is perfectly suited to


extreme and harsh conditions. It monitors up to fi ve types of gas, which includes methane, carbon dioxide, hydrogen sulphide and VOCs. The instrument’s multiple functions offer selectable sampling times ranging from 40 to 10,240 second intervals. Samples taken from targeted areas go through a selectable purge period during which the measurement system is fl ushed with clean air, so sensor cells maintain optimum performance. An integral peristaltic pump fi nish the procedure by removing moisture is at specifi ed timed intervals.


Operators of this gas sampler set sampling time, clean air purge time and condensate drain cycle time which can be specifi ed according to site conditions and sampling requirements. Continuous gas readouts further improve the performance of the system and all sensor 4~20mA signals are maintained in all selected function time periods.


GDS Technologies’ patented micropore sampling (MPS) complements the GasVac® samplers by integrating a sampling line that can be either a continuous length or modular, enabling multiple ‘single intake point sampling’ as well as ‘area sampling’ from the whole surface area of the line. The versatile, compact and precise micropore system can be installed in confi ned spaces like tunnels or perimeter monitoring of storage tanks and monitoring a combination of lighter and heavier than air gases.


The GasVac® Solo is simple to install and


needs hardly any maintenance and offers a low-cost solution with a high level of accuracy and dependability, protecting people and assets from toxic, fl ammable and asphyxiate gases.


The GacVac® as the GasVac®


Solo+ has all the same features Solo but with the capability of


sequential sampling of up to eight sample lines, making it a perfect tool for large tank farms.
