Waterproof EcoTestr™ CTS Water Quality Meter

Article No. 10856

Pocket Conductivity Salinity TDS Meter

The Waterproof EcoTestr™ CTS Water Quality Meter makes measuring water quality easier and faster. The redesigned display is larger with a better viewing angle, has indicators for battery life, readiness, and calibration, and shows both the parameter and temperature readings at the same time. 

$99.00 excl. taxes & shipping cost


  • Larger display with a better viewing angle
  • Conductivity, TDS, and salinity in one meter
  • Expanded 4-digital dual-line display shows parameters and temperature reading simultaneously
  • Additional key provides an easier more intuitive interface
  • Automatic temperature compensation ensures accurate reading in varying environments
  • Easy-to-navigate interface for quick setup and calibration
  • Redesigned leakproof cap functions as a sample cup and as stabilizing base to stand the meter upright
  • Rugged IP67-rated housing is dustproof and waterproof - and it floats
  • Lanyard attachment makes field measurements more convenient
  • Battery level indicator flashes when battery is low
  • Batteries are included - ready to go right out the box!
  • Applications: agriculture, aquaculture & aquariums, cooling towers, education, electroplating, environmental, monitoring, food & beverage, hydroponics, photo development, manufacturing, pools & spas, printing, water & wastewater treatment
  • To enhance field use, the cap was redesigned to be leakproof and can be attached to the top of the meter when not being used; no more lost caps! The cap features a fill line, so you know how much sample you need for an accurate reading when using the cap as a sample cup. It is also wider, providing a base to keep the meter upright for hands-free measurements.
