Lutron PWA-301 Pen Type Digital Conductivity Meter measures from 0 to 1,999 micro-Siemens per centimeter.

The Pure Water Tester (Water Quality Meter) was designed to check the purity of water by way of the water's conductivity. It is used to measure the conductivity value (from 0 to 1,999 micro-Siemens/cm) which can assist in evaluating whether water is pure or not. The conductivity value will be lower when a low level of impurities exist in the water (for example, distilled water has a low conductivity value that is equal to or less than 10 microSiemens/cm).

  • All-in-one conductivity meter with integral electrode.
  • Microcomputer circuit, intelligent function, high accuracy.
  • Tests water quality for drinking, industrial use and water filter effectiveness.
  • IP-67 water resistant heavy duty housing.
  • External calibration buttons.
  • Highly reliable carbon rod electrode.
  • Built in temperature sensor with ATC (Automatic Temperature Compensation).
  • Compact size, easy operation & light weight.
  • Data hold feature.
  • Auto power off (after 10 minutes of inactivity).
  • Record Minimum & Maximum.
  • Ideal for water conditioning, aquariums, food processing, photography, schools, laboratories, industrial and quality control.
  • Check the condition of water filters.
