Traceable Platinum High-Accuracy Thermometers displays the minimum/maximum temperatures for last 24 hours (for each hour) and last 7-days (for each day); or last 30 days (for each day). The time/date stamp key shows the exact time and date for all minimum and maximum readings.
The triple-display shows maximum, minimum, and current temperatures. Alarm feature is settable at 0.1° increments and signals when temperature rises above/falls below set points. The visual LEDs and audible alarm signals continuously even if temperature returns to non-alarm range. Cable is waterproof, 120" and micro-thin to allow refrigerator or freezer door to close and tightly seal.
Sealed GRAS bottle is insulated from rapid temperature changes when door is opened. GRAS— liquid generally recognized as safe by US Food and Drug Administration eliminates concerns about incidental contact with food or drinking water. To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).
