Thomas 4367 Traceable Salinity Meter, 0.01 ppt Resolution, +/-2 percent Accuracy

Simply turn on, insert, and simultaneously read result and temperature. Easiest unit ever designed for routine analysis and quality control. Elimination of operator technique permits everyone in the lab to report identical readings. Tough, chemical-resistant, waterproof ABS plastic housing assures a long life in severe lab or harsh plant environments. Large 1/2" high LCD digits are easy to read. Dual display shows reading and temperature. Hold button freezes the reading on the display. Arrow keys allow fast setting to calibration standards. Calibration data is saved even when unit is turned off. Instant-response probe and solid-state thermistor provide precise readings. Temperature compensation permits readings to be automatically referenced to the international standard of 25 degree C or user may set a programmable temperature coefficient. To assure accuracy an individually serial-numbered Traceable certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Waterproof unit is 6.5" x 1-2/5" x 1.25", weight is 2.25 ounces. 0.00 to 10.00 ppt and 10.1 to 70 ppt salinity range. 0.01 ppt Resolution. +/-2 percent full scale + 1 digit Accuracy. 32 to 122 degree F Temperature range. 0.1 Degree temperature resolution. +/-0.5 Degree temperature accuracy. 25 degree automatic temperature compensation.
