- Probe is sealed in glycol solution
- Min/max memory
- High and low settable alarms
Accurately monitor temperatures in freezers, water baths, heating blocks, incubators, and refrigerators with this enclosed "temperature-buffered" sensor. Bottle insulates sensor from rapid temperature changes when door is opened.
Records high/low readings
Triple display simultaneously shows high, low, and current temperatures. Min/max monitors high/low readings overnight, on weekends, or for any time period—a significant advantage over "current reading-only" glass thermometers. Range is -58 to 158°F and -50 to 70°C with a resolution of 1° and accuracy of ±1°C.
Signals out-of-range conditions
Alarm feature provides alert when temperature rises above or falls below a set point. Alarm is programmable in 1° increments. Visual and audible signals continue even if temperature returns to non-alarm range. Ten-foot micro-cable permits refrigerator doors to close on it.
Solid-state probe eliminates mercury contamination in refrigerators. Probe is sealed in a miniature bottle (1 x 2-1/2 inches) filled with patented nontoxic glycol. Solution is GRAS (generally recognized as safe) by the FDA (Food and Drug Administration). Eliminates concerns about incidental contact with food or drinking water.
Traceable® to NIST for accuracy
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).
High-impact, chemical-resistant ABS case is 2-3/4 x 4-1/4 x 3/4 inches. Weight is 4 ounces. VELCRO™ and magnetic strips are provided for mounting of both thermometer and bottle sensor. Supplied with a Traceable® Certificate and AA battery for continuous, 1-year "always-on" monitoring.
The Plus™ model features High-Resolution, High-Accuracy and Min/Max Memory (Identical to 291-4127 but with a range of -40.0 to 122.0°F (-40.0 to 50.0°C) a resolution of 0.1°, an accuracy of ±0.5°C, and without an alarm.)
