Smart-Alarm™ signals out-of-range conditions

When an out-of-range condition is sensed, the Smart-Alarm™ triggers. Smart-Alarm™ features visual and audible indicators which signal continuously until acknowledged, even if the parameter returns to the non-alarm range. Alarm is programmable in 0.1° increments


Bottle Probe

Solid-state probe eliminates mercury contamination in refrigerators. Ten-foot micro-cable permits refrigerator doors to close on it. Probe is sealed in a miniature bottle (1 x 2-1/2 inches) filled with nontoxic glycol. Solution is GRAS (generally recognized as safe) by the FDA (Food and Drug Administration). Eliminates concerns about contact with food or drinking water.


Traceable® Certificate

Multi-point calibration on an individually-numbered Traceable® Certificate which assures accuracy from our ISO/IEC 17025:2005 (1750.01) calibration laboratory accredited by A2LA.  It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. High-impact, chemical-resistant ABS plastic case is 2-3/4 x 4-1/4 x 3/4 inches. Weight is 4 ounces. Supplied: Traceable® Certificate, flip-open stand, wall mounting, Velcro®, and magnetic strips.
