Thomas 4239 High Accuracy Traceable Probe 2-Bottle Refrigerator Thermometer -58 to 158°F
Thomas Hi-Accuracy NIST refrigerator thermometers are traceable and meet all CDC requirements for thermometers and vaccine thermometers. The dual-reading thermometer has a temperature range of -58 to +158 degrees Fahrenheit / -50 to +70 degrees Celsius with an accuracy of +/- 0.3 degrees Celsius and is suitable for use in refrigerators, bathrobes, heating blocks and incubators. Includes a selection of storage bottle temperature sensors or sensor type sensors. The probe sensor is waterproof and chemical resistant. Sensor The sensor is 3/16" in diameter and 3/4" long. The storage bottle temperature sensor contains non-toxic glycol and insulates the probe, making it less sensitive to temperature fluctuations when the door is opened. Glycol solutions are generally considered safe (GRAS). 2-1/2 x 1 inch bottle ((H x W, where H is the vertical distance from the lowest point to the highest point; W is the width, and the horizontal distance is from left to right). A small 10-foot cable door is used on scales Cable tray thermometers measure temperature in a variety of applications such as education, general quality control laboratories, research laboratories, and biological process control.
This thermometer has a socket for up to two sensors, is accurate to 0.01 degrees and displays temperature in Fahrenheit or Celsius. The three-line LCD displays the minimum, maximum and current temperature of each probe. Temperature alarms can be set in 0.1 degree increments. Dual channel alarms provide visual and audible alerts of out-of-range temperatures for each individual probe. The alarm will continue to sound even after returning to the no-alarm area. The thermometer records the date, time, and length of time that the probe was exposed to temperatures outside the range. The thermometer has a shock-resistant, chemical-resistant ABS plastic casing. 4.25 x 2.75 x 0.75 inches (H x W x D, where H is the vertical distance from the lowest point to the highest point; W is the width and horizontal distance from left to right; D is the depth and horizontal distance from front to rear right), weighs 5 ounces . The thermometer has an integrated base and wall mount and can also be attached with Velcro or magnetic strips. It is powered by two AA batteries (included) and provides up to a year of continuous monitoring.
