devices via Bluetooth Low Energy. The MX2001 simplifies and lowers the cost of field data collection by providing wireless access to high-accuracy water level and temperature measurements directly from a mobile phone or tablet. Researchers no longer need to take a laptop computer out to the field or pull data loggers out of a well to download data. And, no internet access is necessary; the logger and mobile device are all that's required. The Hobo MX2001 offers a number of additional features to streamline water level data col- lection: It features a non-vented design for convenient and hassle-free deployment, an integrated barometric pressure sensor that eliminates the need to post-process data, and user-replaceable double-A bat- teries that last up to a year in the field. It also has a durable ceramic pressure sen- sor that can withstand harsh underwater environments, including saltwater and ice. The free HOBO mobile app makes it sim- ple to configure Hobo MX2001 water level loggers and manage the collected data in the field. Using a mobile phone or tablet, users can enter reference water levels, view level data, check logger status, share data files for analysis in spreadsheets, and store data in the cloud. Users can also select alternate logging modes, such as multiple-rate sampling, which allows faster sampling at critical times, like when pumping starts or stops. www.onsetcomp.com Injectable Resin Consolidates Loose Rock Strata Worldwide announced a new exclusive supply agreement with Grace Construction Products to introduce Organosol 550DT, a non-expanding, two- component rock consolidation injection resin that offers mines an advanced alter- native to traditional urea-silicate glues. It is designed to consolidate and stabilize fractured coal, rock, and gravel in under- ground roadways, shafts, coal faces and longwalls. Organosol 550 DT is insensi- tive to water in the reaction and will not absorb, shrink, expand or foam when it comes into contact with water. It can be used to seal against water. www.strataworldwide.com DECEMBER 2015 • E&MJ; 93 www.e-mj.com E Q U I P M E N T G A L L E R Y
