The AND1000 fluorimeter is a new technology that uses DNA to detect metals in water in 30 seconds. The handheld device tests drinking water, environmental water and industrial water supplies. It uses an extremely sensitive measurement technique to determine the toxicity levels of heavy metal contamination to low parts-per-billion levels.
The upgraded DM-2 dual inline TDS monitor, featuring a wide measurement range (0 to 9,990 ppm); a large, easy-to-read LCD; splash-proof design; and flexible mounting bracket, now offers improved accuracy, digital calibration, self-diagnostic messaging and shielded cables. It is ideal for a variety of commercial or light industrial water filtration systems, such as reverse osmosis and deionization. The monitor was co-designed in the U.S. and South Korea, and is backed by a one-year factory warranty.
The Ultrapen PT1 conductivity/TDS/salinity tester features the accuracy and stability of bench top lab equipment with the convenience of a pen. Constructed of durable aircraft aluminum, the pen is fully potted for extra protection, with an easy-to-read LCD and one-button functions.
Detecting heavy metals in drinking water
HM Digital’s QC-1 is a “Push-to-Test” TDS monitor designed to monitor the effectiveness of any water purification and filtration system that removes TDS. The unit is battery operated and can be easily installed in minutes. It has eight programmable settings (by dip switch) for either TDS or conductivity. Once installed, a user simply needs to press the button. If the TDS level is below the set point, a green light will be illuminated. If above the set point, a red light will display, indicating service is required. It’s backed by a one-year warranty.
