  • Easy-view, jumbo 1.5 in. (3.8cm) digits are able to be read from 30 ft. (9.1m)
  • Sensor and 10 ft. (3m) cable perform accurately even when both are under water
  • High-impact, chemical-resistant ABS plastic case
  • Available with sealed probe or naked sensor

Record Maximum/Minimum Readings
  • Triple display simultaneously shows maximum, minimum and current probe temperatures plus room temperature
  • 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 0° and accuracy of ±1°C
Superior Design for Safe Operation
  • Alarm feature provides alert when temperature rises above or falls below a set point
  • Alarm is programmable in 1° increments
  • 10 ft. micro-cable permits refrigerator doors to close on it
  • Solid-state probes eliminate mercury contamination in refrigerators
  • Sealed probe is housed in a miniature bottle filled with 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

Order Info: Case: 3.88 × 4.38 × 0.88 in. (9.9 × 11.2 × 2.2cm). Sealed bottle probe measures 1 × 2.5 in. (2.5 × 6.4cm). Naked sensor is 0.19 dia. × 0.75 in. (4.8 × 19mm) long.
