Manufacturer: Thomas Scientific Brand: Thomas Model: 4365

The Thomas 4365 Traceable Conductivity meter is a waterproof, pen-style instrument designed for easy routing analysis and quality control, with automatic or manual range selection. The LCD screen displays readings in digits that are 0.5” in height, and the meter housing is ABS plastic for durability in harsh laboratory or plant environments. Automatic shutoff after 20 minutes of non-use helps preserve battery life. Conductivity meters are commonly used in the water-quality testing, waste-water treatment, hydroponics, agriculture, and aquaculture industries, in cosmetics manufacturing, and in laboratory research. To ensure accuracy, the meter includes an individually serial-numbered Traceable certificate from an ISO 17025 calibration laboratory accredited by the American Association for Laboratory Accreditation (A2LA). The certificate indicates traceability to standards provided by National Institute of Standards and Technology (NIST). The meter also fulfills requirements for CAP, ASTM, NCCLS, CLSI, ACS, CLIA, AOAC, EPA, APHA, AWWA, WEF, USGS, USP, ISO, and federal and state regulations. Specifications Conductivity range 0 to 1999μS, 0.00 to 19.99mS Conductivity resolution 1, 0.01 Temperature compensation Automatic from 0.0 to 50.0 degrees C, with temperature coefficient equal to 0.0 to 4.0% per degree C, 0.1 increments Power source Four 357/LR44 silver oxide batteries Dimensions 6.5 x 1.25 x 1.25” (H x W x D)Weight2.25oz  Conductivity meters, also known as electrical conductivity (EC) meters, measure the ability of a solution or material to conduct an electrical current. This measurement helps determine if the solution is, for example, contaminated or contains too much saline. In general, pure solutions, such as distilled water, have low conductivity. More saline- or nutrient-rich solutions, such as seawater or fertilizers, have high conductivity. Conductivity measurements are often used with total dissolved solids (TDS) measurements, which are typically expressed in ppm (parts per mill...
