Digi-Sense, 90002-02, Traceable Time and Date Digital Thermometer with Calibration, Bottle Probe, NIST CertificateFeatures with all optional accessories:Minimum and maximum readings are time/date stampedGet accurate, reliable measurements with included NIST-traceable calibrationSimultaneously displays temperatures and timeWire mounting bracket permits easy probe placementIncludes:NIST-traceable calibration certificate with dataone AAA alkaline batteryIdeal for monitoring temperature in the lab, home or office. Thermometer includes a remote probe with 6-ft (1.8m) cable to measure outdoor temperature and an internal sensor to measure indoor temperature. Display can be changed to show probe or ambient temperature, time of day and month/day. Thermometer can also display the exact time and date when the minimum and maximum temperature occurred. The temperature sensor performs accurately in most environments even including under water. Use rear stand to place unit on table or attach to wall via Velcro strip or the two rear-mounted screw holes. 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.Supplied with 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 opened.
