Keep track of temperature conditions overnight or for any time period-minimum and maximum temperatures are stored until the memory is cleared. The 4-wire platinum probe insures linear response and high accuracy across the entire range. The built-in alarm provides an alert when temperature rises above or falls below a user defined set point and is programmable in 1° increments. A visual and audible signal continues even if the temperature returns to non-alarm range until reset by the user. 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. 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.
