The Extech Waterproof Temperature Indicator contains a fast-response sensor to measure temperature in liquids, semi-solids, and air.
The Extech Waterproof Temperature Indicator provides audible and visual alarm alerts when temperature levels are higher or lower than the user programmed high/low set points. The fast response sensor measures temperature in liquids, semi-solids, and air. LCD displays temperature reading, alarm indicator, and high or low alarm icons.
The TM20 includes a 0.78 inch stainless steel probe with 9.6 foot cable. The sensor measures temperature from -40°F to 158°F. The TM25 model includes a 4.1 inch stainless streel penetration probe with 5 foot cable. The sensor measures temperature from -40°F to 392°F.
The unit has a magnetic back and can be mounted on a metal surface, used on a desktop with the foot stand, or mounted on a wall. The waterproof housing and sensor are waterproof and designed to meet IP65 ratings.

Unique among the 29 National Estuarine Research Reserves (NERRS), Narragansett Bay National Estuarine Research Reserve (NBNERR ) is made up of four islands: Prudence, Patience, Hope and Dyer. Protecting about 4,400 acres of land and water, NBNERR is a great place to see a variety of coastal habitats. There are upland maritime forests, coastal pine barrens, sandy beaches, cobble shorelines, salt marshes and open grasslands. NBNERR also has excellent hiking, fishing, clamming and bird watching. “If you want to see us, though, you’ll need to hop on a ferry,” says Bob Stankelis , NBNERR Reserve Manager. “Or you’ll have to take a boat. We’re not that easy to get to. But to be honest, that’s one of the big things residents here like about it: its remoteness.Read More
Since the 1980s, scientists from the Vermont Department of Environmental Conservation (VT DEC) have been sampling water from acid-impaired ponds and lakes and tracking data related to acidity. The line of inquiry began in response to concerns about acid rain, but DEC scientists now find that the long-term monitoring is not only proving the efficacy of the Clean Air Act but also improving local water quality.
Guarding the environment in Vermont
Rebecca Harvey is a VT DEC scientist, and monitoring the state's waterways for acidity and other problems falls in part to her. Dr. Harvey corresponded with EM about this work.Read More
In the ongoing quest for better wastewater treatment, a team of researchers from the University of California, Riverside (UCR) have developed a technique to improve the way Advanced Oxidation Processes (AOPs) remove pollutants from wastewater dramatically. AOPs remove organic materials from water using oxidation.
These AOP reactions take place when hydrogen peroxide, a powerful oxidizing agent, decomposes, leaving hydroxyl radicals along with oxygen and water behind. This makes the processes appealing, but until now they've required both a long period of time and large amounts of both hydrogen peroxide and ferrous salt (Fe2+, a divalent iron ion). The Fe2+ acts like a catalyst, but also produces a secondary pollutant in the form of an iron-containing sludge.Read More
