Digi-Sense, 94460-71, Traceable Fridge/Freezer Digital Thermometer with Calibration, 5 mL Bottle Probe, NIST CertificateFeatures with all optional accessories:Monitor minimum and maximum temperatures - all at a single glanceGet accurate, reliable measurements with included NIST-traceable calibrationTriple-display-shows high, low and current temperature simultaneouslyIncludes:NIST-traceable calibration certificate with dataplastic standdouble back tape and Velcro for attaching holder to any surfaceprobetwo AA batteriesEasily monitor temperature in liquids, baths, air/gas, incubators, refrigerators, or freezers. Keep track of temperature conditions overnight or for any time period - minimum and maximum temperatures are stored until the memory is cleared. Models feature a triple display that simultaneously shows current, minimum and maximum temperatures. Set high and low alarms in 1° increments, alarm sounds when temperature rises above or falls below set points and continues to sound even if temperature returns to nonalarm range. Thermometer reads ambient temperature or probe temperature. Probe is attached to a 10-ft (3 m) micro-cable that permits a doors to close on it; probe and cable are both submersible. Mount meter with included Velcro strips, wall-mount slots, or use flip-open stand on benchtop.Supplied with a special bottle probe specifically designed for refrigerator/freezer applications. The temperature sensor is enclosed in a bottle, which protects it from rapid temperature changes when refrigerator door is openedTraceable 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.
