GrayWolf has introduced new multi-parameter air measurement kits that include 7-in, 8-in, or 10-in tablet PCs to meet lower cost DirectSense IAQ, TVOC, TOX, HVAC and AIR applications. Use the smaller tablets for portable display of measurements, “snap-shot” data-logs, and/or short-term trend logging. Additionally, use the 10-in tablet for multi-probe and long-term monitoring. All of the tablets come with cameras that enable direct attachment of photos and videos to data files on-site. The microphones allows for audio note attachment for efficient and reliable documentation of field surveys.
CertainTeed has expanded its line of Ecophon sound absorbers. According to the company, the Ecophon Advantage makes specifying fiberglass ceilings a viable choice in a wide variety of settings. Manufactured at CertainTeed’s facility in Plymouth, WI, the Ecophon Advantage aims to offer a cost-effective solution for bringing outstanding acoustics and environmental performance to a larger list of projects. Schools, offices, and other public buildings can now add the sound absorbing performance of fiberglass in high square footage applications such as classrooms and open-plan offices to basic mineral fiber ceilings and stay within budget.
Power management company Eaton has released its new BRX miniature circuit breaker. The product aims to will provide design freedom by reducing costs and making installation easier. By implementing the BRX miniature circuit breaker, there is no need for specified upstream breakers, and this allows contractors to use less expensive service modules. Fully rated at 65,000 amperes interrupting capacity (kAIC), Eaton officials claim its 1-in style, two-pole breaker is a market leader for interrupting ratings in a standard-size miniature breaker package.
B&K Precision introduced the 9200 Series, its latest multi-range programmable DC power supply line.
