The Extech Non-Contact AC Voltage and Current Detector is a two-in-one current/voltage detector designed for electrical testing. The detector measures non-contact AC current from 200mA to 1000A and non-contact AC voltage from 12V to 600VAC. The sensitivity adjustments are to increase or reduce sensor trigger threshold. A loud audible and bright visible indicator will alert users if a current or voltage is detected. The curent sensor detects current flow of 400mA at 0.2" distance and at much greater distances for larger current flows.
Applications include detecting trace concelead wires in walls and floors, identifying hot spots, tracing current flow behind walls, in conduit, where voltage detection does not work, and tripping on low voltage HVAC or similar signal levels.

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.
