Fulfill all official lab analysis regulations for CAP, ASTM, NCCLS, CLSI, ACS, CLIA, AOAC, EPA, APHA, AWWA, WEF, USGS, USP, ISO, and Federal/State regulations by using the Bench Conductivity Meter. Simply turn on, insert probe into solution, and read accurate results. Unit automatically encompasses all ranges and selects the most appropriate for the current reading. Disable the auto-range function when user-defined ranges are desired. Control allows user to store four calibration points using solution standards. Ranges are: 0.01 to 200,000 microsiemens (micromhos), 0.001 to 20.000 megohms, 0.1 to 20,000 dissolved solids/parts per million, 2.0 to 42.0 salinity (oceanographic units). Accuracy is ±0.3% +1 digit. To assure accuracy an individually serial-numbered Traceable® Certificate is provided from the manufacturer’s ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). State-of-the-art microcomputer processor and unique software program allow four calibration points to ensure complete accuracy over the entire range. Readings are displayed in conductivity (microsiemens/micromhos), resistivity (megohms), total dissolved solids (milligrams per liter), salinity (oceanographic units), concentration (user specified units), and temperature (Celsius/Fahrenheit). K factor may be adjusted to match each probe. Specifically designed to measure conductivity in water analysis, biology, chromatography, food, and PC board rinsing. Computer output may be downloaded to a data logger or computer for analyzing or reporting at a later time. Makes hard copy results a breeze—no more, hand-scrawled notes to decipher. Supplied probe contains platinum electrodes and a solid-state thermistor for automatic/manual temperature compensation. Readings are automatically referenced to the international standard of 25°C. Temperature compensation is automatic (2% per °C), user-designated (0.000 to 5.000% per °C), or absolute. Exclusive temperature compensation disable function fulfills USP-NF (United States Pharmacopoeia, National Formulary, 645 Conductivity Measurement) requirement. ABS plastic housing withstands the roughest lab environments. Unit comes with 115 VAC adapter, probe replatinizing current, a probe holder arm, battery, and Traceable® Certificate. Supplied glass probe is 5-1/4 x 1/2 inches diameter with a cable length of 59 inches. Size is 8-1/4 x 6 x 3-1/2 inches and weight is 1-1/2 pounds. Replacement battery Cat. No. CON1112.
