Why Buy From Fondriest?


The Extech Dual Laser InfraRed Thermometer features a fast 100mS response with highest accuracy at a point where the dual lasers converge. The fast response is ideal for quick checks of multiple spots in a process or for catching spikes in temperature. The high 50:1 distance to target ratio measures smaller surface areas at greater distances. 


A type K thermocouple probe input ranges from -58 to 2498°F (.50 to 1370°C). The white backlit multifunction LCD displays a bargraph for analysis of data points. The adjustable high/low set points with audible alarm alerts users when the temperature exceeds the programmed set points. Also included is a tripod mount for continous readings, and software to connect to a PC via USB port.

Notable Specifications:
  • Laser convergence distance: 50" (127cm)
  • IR range: -58 to 3992 F (-50 to 2200 C)
  • Repeatability: +/-0.5% or 1.8 F/1 C
  • Basic accuracy: +/-(1% of rdg + 2 F/1 C)
  • Max resolution: 0.1 F/C
  • Emissivity: 0.10 to 1.00 adjustable
  • Field of view (distance to target): 50:1
  • Type K range: -58 to 2498 F (-50 to 1370 C)
  • Memory: manually store/recall 100 readings
  • Dimensions: 8x6.1x2" (204x155x52mm)

Cooling water from Northeast U.S. power plants keeps rivers warmer

Rivers are a vital cooling source for power plants, but high-temperature water returned to rivers from the plants may detrimentally heat rivers and change aquatic ecosystems, according to a recent study. Scientists from the University of New Hampshire and the City College of New York gathered federal data on power plants and river systems and linked up river flow and heat transfer models to figure out just how hot rivers get in the northeastern U.S. They found that about one third of heat generated in thermoelectric power plants in the Northeast is drained into rivers via used cooling water. Just more than a third of the total heat generated at plants in the Northeast is converted directly into electricity for consumer use.

Elliott Bay Reconstruction Benefits From Chum Salmon Finds

Like many commercial waterfronts, Seattle’s Elliott Bay has been built to withstand the natural forces of erosion. This has come with the addition of structures like concrete seawalls and piles of riprap, most of which were put in place in the 1930s. But there are a few manmade beaches that have sprung up in recent years along its banks. Some of these have come about because the city is reworking the shoreline following an earthquake that occurred around 10 years ago. And moving forward, Bay planners are looking to add still more improvements, including complexities in seawalls, underwater benches in the intertidal zone and a new beach, all of which are meant to help support fish habitat.

Boise River Watershed Watch Shows Volunteers Issues River Faces

Having just wrapped up its ninth year, the Boise River Watershed Watch program is an increasingly popular citizen science program in Boise, Idaho. It takes interested volunteers and joins them with expert scientists from the U.S. Geological Survey (USGS) who teach them about the river’s health and sampling water quality using transparency tubes, dip nets and chemical test kits. “Our focus is to educate folks on the parameters that we measure, to give them an idea of the river’s health,” said Tim Merrick, public information officer at the USGS’ Idaho Water Science Center. “So they can collect data on the river’s conditions and get plugged in.
