Traceable® Portable Conductivity Meter, 3.75 x 0.5 x 6.75", Black

In an instant, portable conductivity meter automatically selects the proper range and displays the exact answer without hassles. This auto-ranging feature may be turned off to accommodate user-entered ranges. All special calibration data is saved even when unit is turned off. Fulfills all government measurement requirements plus CAP, ASTM, NCCLS, CLSI, ACS, CLIA, AOAC, EPA, APHA, AWWA, WEF, USGS, USP, ISO, and Federal/State regulations. Range in micro Siemens (micromhos) is 0.01 to 200,000, in megohms is 0.001 to 20, range in dissolved solids/parts per million is 0.1 to 20,000, and in salinity is 2 to 42 (oceanographic units). Accuracy is ±0.3% +1 digit. Supplied instant-response probe contains platinum electrodes that deliver highly accurate readings. Internal solid-state thermistor (for automatic/manual temperature compensation) permits all readings to be 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. K-factor may be adjusted to match each probe. Exclusive temperature compensation disable function fulfills USP-NF (United States Pharmacopoeia, National Formulary, 645 Conductivity Measurement) requirement. Use to check the purity of water from stills and demineralizers, to analyze seawater, and to make up solutions. Simply turn on, insert probe, and read-easiest unit ever designed for routine analysis, quality control, and research. Elimination of operator technique permits everyone in the lab to report identical readings. Tough, chemical-resistant ABS plastic housing assures a long life in severe lab or harsh plant environments. Large 0.5"high LCD digits are easy to read. To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO/IEC 17025:2005 (1750.01) calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Permanent hard copy record Recorder jack allows continuous monitoring and a permanent record. Arrow keys allow unit to be calibrated to solution standards. Supplied glass probe is 5.25 x 0.5" dia with a cable length of 59". Unit size is 3.75 x 6.75 x 1.5". Weight is 16 oz. Battery is supplied.
