Multiparameter Testing
The Solinst Levelogger 5 combines a pressure sensor, temperature detector, 10-year lithium battery, and datalogger, sealed within a 22mm x 160mm (7/8" x 6.3") stainless steel housing with a corrosion-resistant coating baked-on using polymerization technology.
Hastelloy Pressure Sensor
The Levelogger 5 measures absolute pressure using a Hastelloy pressure sensor and offers high resolution and an accuracy of 0.05% FS. Readings are stable in extreme pressure and temperature conditions. The Hastelloy sensor can withstand 2 times over-pressure without permanent damage. Combined with the durable coating inside and out, the Levelogger 5 has high corrosion and abrasion resistance in harsh environments.
Protective Design
The logger uses a Faraday cage design, which protects against power surges or electrical spikes caused by lightning. Its durable maintenance-free design, high accuracy and stability, make the Levelogger 5 the most reliable instrument for long-term, continuous water level recording.

Water Conservation and Smart Growth in Texas
As states face annual droughts and water use continues to grow in order to meet population and production demands, water conservation is essential to protecting natural resources and long-term reliance. 
 
Over the years, conserving water has become more necessary as the world’s natural resources continue to be strained in order to meet needs. As a result, water conservation consultants have filled an essential niche in resource management. 
 
Eddie Wilcut, the Water &; Energy Efficiency Practice Leader at Plummer , started his career in the Air Force, where he took some classes focusing on water resources. In those classes, Wilcut read Aldo Leopold’s “A Sand County Almanac,” and a specific line has stuck with him for the past 26 years.

As scientists seek to better understand aquatic ecosystems, utilizing small data buoys to monitor offshore and cover more water is becoming commonplace. The new NexSens Technology XB-200 data buoy was designed for inland and coastal monitoring applications. 
 
Although compact, the platform is designed with adequate space for multiple sensors and measurement electronics. When configured with the NexSens X3 data logger with IoT connectivity, internal batteries, solar panels, select sensors, and other accessories, the new buoy provides an off-the-shelf solution for any monitoring project. 
 
The new buoy concept was developed by the NexSens product development team with significant user input.

Ice cover on the Great Lakes provides numerous recreational and economic opportunities, including ice fishing, snowmobile charters, and ice caves on the lakes. Unfortunately, declining ice cover and increasing related weather events due to climate change, as well as other environmental stressors, have put such opportunities at risk. 
 
 Historically, understanding winter weather has been difficult largely due to a lack of observations and, as a result, communities surrounding the Great Lakes have been left underprepared for extreme events.
