The Extech 5-Frequency Passive Component LCR Meter measures inductance, capacitance, and resistance.
The Extech Passive Component LCR meter accurately measures capacitors, inductors and resistors using the test frequencies of 100Hz, 120Hz, 1 kHz, 10kHz, and 100kHz. The dual display will simultaneously display the associated quality factor, dissipation or phase angle value using a series or parallel equivalent circuit. The meter includes 5 frequencies, including an auto select function with 1kHz default test frequency. User select high/low limits using the absolute values or percentage limits. Open and short calibration removes unwanted stray impedances from the measurement.

Cary Institute of Ecosystem Studies , an independent environmental research organization in Millbrook, NY, is a leader in environmental monitoring – particularly long-term monitoring that spans decades.
Steve Hamilton is a freshwater ecologist at Cary Institute and professor at Kellogg Biological Station , a member of the Organization of Biological Field Stations ( OBFS ), at Michigan State University. Hamilton explains, “Environmental monitoring is how ecologists keep a finger on the planet’s rapidly-shifting pulse. By tracking ecological indicators over long timescales, we can identify patterns and better understand how ecosystems are changing. This understanding will guide us as we work to adapt to and mitigate environmental degradation.Read More
In drought-stressed areas like California where every drop in the aquifer counts, seismic noise may be the key to monitoring water. Harvard University PhD student and principal investigator Tim Clements spoke to EM about this recent work, and how it might be a game changer for water watchers across the country.
“The inspiration for this research was the historic drought in California from 2011 to 2017,” explains Clements. “This was the driest period in recorded history in the state. We started this research after California had implemented the first mandatory water restrictions in state history in 2015.”
According to Clements, the team focused their study on the San Gabriel Valley in Los Angeles County for several reasons.Read More
As of 2018, 75 percent of the main channel of the Mississippi River is monitored for water quality. This step forward is the result of an agreement between more than 30 mayors from cities close to the Mississippi River, the Mississippi River Cities and Towns Initiative . Super gauges now monitor nutrients along the river, and Scott Morlock with the US Geological Survey (USGS) spoke to EM about this project.
