Digi-Sense, 90080-09, Traceable Scientific Thermistor Thermometer with Calibration, USB Probe, NIST CertificateFeatures with all optional accessories:A highly accurate thermometer that is simple to useGet accurate, reliable measurements with included NIST-traceable calibrationResolution of 0.001°F/°CIncludes:NIST-traceable calibration certificate with datageneral-purpose penetration probeplastic carrying caseone 9 V batteryThis high-precision thermometer is ideal for measuring temperatures in gas systems, reagents, chemical solutions, soil, water baths, ovens, incubators, pharmaceuticals, foods and wastewater. Designed for years of reliable service even in severe environments, the meter features a splash proof membrane keypad. A high-contrast 1/2"-high LCD makes the thermometer easy to read in all types of light. The meter features memory and hold function, internal datalogger that captures the min/max temperature every hour for a 24-hours period and °F/°C selection. For easy reading, the meter can be changed to display one, two, or three significant numbers after the decimal point. The fast-response general purpose probe (included) displays even the slightest temperature change instantly. Readings are updated three times a second. Traceable products are calibrated to NIST-traceable standards and ready to use as soon as you receive it. Each product goes through an intense vetting process before it can carry the Traceable name and it includes NIST-traceable certification. This means that a 17025-accredited calibration test lab has confirmed that the product meets or exceeds all stated specifications, saving you both time and money by not having to calibrate separately. NIST-traceable calibration also helps you meet quality standards and regulatory compliance for ISO, FDA, cGMP, VFC, CAP, CLIA and Joint Commission requirements.
