The Hach sensION+ 5021T is a glass combination pH electrode with a refillable reference electrolyte and built-in temperature sensor. The 5021T has a fixed 1 meter cable with BNC connector (pH) and banana (temperature) connectors. It is intended for use with Hach sensION+ Laboratory pH meters. The 5021T has sleeve junction with a design that ensures high electrolyte flow making it very hard to clog, as well as an encapsulated reference system with silver ion barrier. It and is ideal for pH measurements in low ionic strength applications, samples with colloids, wines and paints or viscous samples such as emulsions and creams.


The 5021T's ContATC sytem provides precision temperature measurement required for high performance analysis. This patented system utilizes a thermo-conductive silicone to improve the speed and performance of the Pt1000 temperature sensor.

Notable Specifications:
  • Filling Solution: LZW9500.99
  • Material Sensor Body: Glass
  • Special Feature: Clog-free Sleeve Junction for low ionic strength.
  • Temperature Range: Continuous use: 0 - 60 °C
  • Thermistor: Pt1000

Ocean acidification: University of Washington's giant plastic bags help control research conditions

With oceans becoming more acidic worldwide, scientists are getting creative in designing experiments to study them. For example, one group at the University of Washington is using giant plastic bags to study ocean acidification. Each bag holds about 3,000 liters of seawater and sits in a cylinder-like cage for stability. The group at UW, made up of professors and students, is controlling carbon dioxide levels in the bags over a nearly three-week period, during which they are looking at the effects of increased acidity on organisms living near the San Juan Islands. “These mesocosms are a way to do a traditional experiment you might do in a lab or classroom,” said Jim Murray, professor of oceanography at the University of Washington.

NOAA Alaska buoy network to monitor North Pacific ocean acidification

National Oceanic and Atmospheric Administration scientists detected signs of ocean acidification in the waters that hold the vulnerable and valuable fisheries of the North Pacific off the coast of Alaska, but they only had a snapshot of the action. “We know that in this place were important commercial and subsistence fisheries that could be at risk from ocean acidification,” said Jeremy Mathis, a NOAA Pacific Marine Environmental Laboratory researcher and professor at the University of Alaska Fairbanks. To understand how ocean acidification affects the North Pacific, NOAA scientists created a mooring network that collects constant in situ data on parameters contributing to acidification. They hope it will reveal seasonal trends and patterns left out by their snapshots.

First Environmental Monitoring System For Baltimore’s Inner Harbor

Baltimore’s Inner Harbor and the rivers that flow into it are important sources of water to Chesapeake Bay, popular recreation sites and the targets of an ambitious clean-up plan. But the city has for some time lacked an environmental monitoring system for tracking water quality in the harbor continuously. That is about to change, thanks to a collaboration between the U.S. Geological Survey (USGS) and Environmental Protection Agency (EPA). It will lead to the new installation of a suite of sensors that will provide the public and scientists with the first comprehensive, real time look at water quality in the harbor.
