Traceable® Min/Max Digital-Bottle™ Refrigerator/Freezer Thermometer with a NIST Traceable® Calibration Certificate (each)

**Filled with glass beads and NO solution**

Provides accurate readings everywhere
Accurately monitor temperatures in freezers, refrigerators, incubators, and environmental chambers with this temperature-buffered sensor. Bottle and solution insulate sensor from rapid changes, as an example, when a refrigerator door is opened. Solution mimics exact temperature of samples. Stainless-steel sensor/probe assures long product life. Entire unit is waterproof.

Records high/low readings
Easy-to-read digital display shows high, low, and current temperatures. MIN/MAX monitors high/low readings overnight, on weekends, or for any time period—a significant advantage over impossible to read glass thermometers displaying only the current temperature. The entire unit including bottle and display may be placed in any environment within the operating temperature range of –20 to 50°C (–4 to 122°F). The resolution is 0.1°. Accuracy is ±0.5°C between 0° to 50°C ; otherwise ±1°C.

Supplied with unique holder
Chemical-resistant ABS plastic holder stands on a shelf or holder side affixes to a refrigerator wall or any wall. Supplied with double back tape and Velcro® for attaching holder side to any surface. Bottle may be removed from holder.

Digital-Bottle™ eliminates mercury contamination
Solid-state probe eliminates the difficulty encountered with mercury thermometer contamination. Probe is sealed in a miniature bottle filled glass beads.

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). Supplied complete with holder, double back tape, Velcro®, and replaceable silver-oxide battery. Unit size is 1-7/8 x 1 x 4-5/8 inches, holder is 2-1/4 x 2-1/4 x 1-1/8 inches. Weight is 3-2/3 ounces.
