The Extech Multifunction Process Calibrator is used for precision source and measurement for thermocouples (types J, K, and T), mA, mV, and V devices. The source is from 0 to 24mA with a 0.1 resolution, and measures from 0 to 50mA. The output is from 0 to 1999mV or 0 to 10.00V, and measure from 0 to 19.99V. User selectable type J, K, or T thermocouples are used for precision calibrations in °F/°C or mV. The self-contained 24V loop power supply drives current loads up to 1000Ω, and the memory for 5 user settable output values of each type for fast calibrations.

In The News
In the early days of the Covid-19 pandemic, there was a period of unexpected environmental optimism.
Wild goats roamed the streets of a town in Wales after its residents retreated indoors. Air quality improved in metropolises around the world. As shipping paused or slowed down, the oceans were quieter than they have been for some time.
Now research shows that water quality improved around Key West, Florida, during 2020, a year in which the Covid-19 pandemic kept people indoors and slowed boat traffic.
A Visible Difference
Henry Briceño first found out about the clearer water around Key West from locals who noticed a difference. So he decided to check those observations against the data.Read More

The Charles River used to be a swimming hotspot for Cambridge and Boston residents.
Decades of industrial pollution and nutrient runoff have degraded water quality and eliminated public swimming in the Lower Charles, but a movement is afoot to get Boston and Cambridge back in the water. One step toward the goal of a safely swimmable river—without the need to obtain a permit, as is now necessary—is detecting and managing the harmful algal blooms that appear on the river.
An experimental floating wetland and new research and analysis of water quality data that shows a possible effective detection system for algal blooms on the Charles River are two new steps toward the goal of safe, accessible swimming.Read More
