HI5000 Series advanced research-grade benchtop meters have a color LCD, capacitive touch keys and a USB port for computer connectivity. The user interface is adaptable, allowing users to display various measurement modes, real-time graphing and GLP data. Additional features include custom calibration options and buffers, three types of data logging, programmable alarm limits and a contextual help key.
HI2002 pH/ORP, HI2003 EC/TDS/Salinity and HI2004 DO edge meters are full-featured yet affordable. Each unit is thin and lightweight, measuring ½ in. thick and weighing 9 oz. The versatile design allows them to be used like benchtop or portable meters, which can attach to a wall to free up valuable bench space in a laboratory. All meters use digital smart electrodes that feature a built-in microchip that stores sensor type, identification and calibration information that is automatically retrieved by the meter when the electrode is plugged in.
AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.
The device uses sound waves to measure water levels
Imagine turning on your faucet only to find there is no water flowing. Your well has run dry, and you have to pay tens of thousands of dollars to fix it. That is the scary scenario for communities grappling with drought, and it is a potential danger for the 43 million Americans nationwide (15% of the population) on well water.
MJ-SDC multi-jet water meters are available for ¾- to 2-in. pipe sizes. They are dry dial-type totalizing water meters, offered with pulse switch outputs of one pulse per 0.1, 1, 10 or 100 gal. A 59-in. length of two-conductor wire, 3.5-mm diameter, is standard. The main casing is made of ECO brass, and the maximum operating temperature and pressure are 122°F and 150 psi, respectively. The meters comply with NSF/ANSI standards 61 and 372, and conform with lead-free plumbing regulations.
The YSI Pro1030 handheld meter measures pH or ORP, plus temperature, conductivity, specific conductance, salinity and TDS. It has user-replaceable pH and ORP sensors, cables and a convenient calibration. Its ruggedness is backed up by military-spec connectors, IP67 waterproof and rubber over-molded case, and 1-meter drop tests. A four-electrode conductivity cell is built into the cable and requires minimal maintenance.

The COM-80 is an economically priced, water-resistant handheld tester for electrical conductivity and TDS, featuring four built-in modes (μS, mS, ppm and ppt). It also includes onscreen diagnostic messaging and temperature on a large four-digit LCD. The tester was co-designed in the U.S. and Korea and is backed by a one-year factory warranty.
