The Extech 1000A Clamp Meter + IR Thermometer is a full size true RMS multimeter that features a built-in non-contact IR thermometer with laser pointer. Multimeter functions included AC/DC voltage, resistance, capacitance, frequency, diode, and continuity. The 1.7" jaw opening fits conductors up to 750MCM or two 500MCM. Unit functions include peak hold to capture inrush currents and transients, data hold, min/max, auto power off, and an autoranging function with manual range button.


The meter comes with an 8-piece professional test lead set. The kti includes two 42" PVC lead extensions with shrouded banana plugs at both ends, two modular 4" heavy duty test probe handles with 0.16" banana plug tip, two standard size alligator clips with insulated rubber boot, and two extra large, double-insulated, alligator clips with sharp teeth for piercing insulated wires. The jaw opens to 0.8".

In The News

The Arizona Department of Environmental Quality's Water Quality Division

With an average rainfall of only 12.5 inches per year and a population that's growing faster than the country's , Arizona is a state that faces unique challenges, especially when it comes to clean, safe water. The Water Quality Division of the Arizona Department of Environmental Quality (ADEQ) protects and enhances public health and the environment by monitoring and regulating drinking water. And although they make use of the latest scientific methods and new technology, given the current state of Arizona's water system, they also rely upon low-tech equipment and cooperation from members of the community to monitor water quality in the state. Team members in the Groundwater Protection Program work to sample, test and characterize groundwater quality in all 51 of Arizona’s basins.

Latest Satellite and Eddy Covariance Data Shows Vulnerability of Trees to Drought

William Anderegg, assistant professor of biology at the University of Utah, has spent years studying drought-stricken trees all over the world. As climate change is expected to cause increased drought severity in the future, the work of Anderegg and his colleagues becomes increasingly important. In a previous interview for the Environmental Monitor , Anderegg found that a tree’s hydraulic safety margin was the best indicator of whether a tree would survive drought. The hydraulic safety margin is an expression of how the tree reacts under drought conditions, where there is very little water being pulled up the tree’s transport system and air is being pulled up instead. “It’s like a heart attack for the tree,” he noted.

A Balancing Act In The Grand Canyon: The High Flow Experiments

You've probably heard of the Four Corners region of the United States; that's where the corners of Arizona, New Mexico, Utah and Colorado meet at one point. These same four states are also part of the Colorado River Storage Project (CRSP), which began to change the face of the American West in 1956, enabling the population explosions in places like Phoenix and Los Angeles to continue thanks to usable water. Glen Canyon Dam is 220 meters high and 480 meters wide, and this massive structure has changed this section of the Colorado River all the way to Lake Mead dramatically. It has also increased low-flow magnitudes, decreased peak flow magnitudes and volumes and caused fluctuations in daily discharge levels that the area relies upon for generation of hydroelectric power.
