Lutron Conductivity/ Water Hardness Meter & Thermometer with Remote CDPB-04 Probe.

Model PWH-303 Water Hardness, Pure Water Meter, measures the concentration of minerals, particularly calcium and magnesium, in water. Hard water is water that has a high mineral content, and it can cause a variety of problems, such as scaling in pipes and appliances, and reduced effectiveness of soaps and detergents. A digital water hardness meter can be used to determine the hardness of water in a home, business, or industrial setting, and can help determine the appropriate treatment for the water to make it more suitable for use. Digital water hardness meters are typically portable, easy to use, and can provide quick and accurate readings of water hardness.

  • LCD with two lines that show hardness/conductivity and temperature value at same time.
  • User Calibratable with Calibration Standard CD-14 (Download instructions).

Lutron Calibration Certificate
Lutron Certificate of Calibration Lutron Instruments & Solutions arrive brand new from Lutron with this factory calibration certificate enclosed. Until our chain of custody is broken we are certain and guaranty that every meter meets this standard at the time of shipment. InspectUSA would need to ship the new meter directly to your NIST lab, with our guaranty that it would meet NIST standards. We must ship the instrument direct to an approved NIST lab for this guaranty to be applicable. Once the chain of custody is broken for whatever reason, this guaranty is no longer valid.
