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. 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 -22 to 122 degree F. The resolution is 0.1 degree . Accuracy is +/-1.0 degree C. Ultra model accuracy is +/-0.4 degree C at tested points. 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. Solid-state probe eliminates the difficulty encountered with mercury thermometer contamination. Probe is sealed in a miniature bottle filled with nontoxic glycol. Solution is GRAS (generally recognized as safe) by the FDA (Food and Drug Administration). It eliminates concerns about incidental contact with food or drinking water. (Also available with glass bead fill.) 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", Holder measures 2.25" length by 2.25" width by 1-1/8" depth.
