Traceable® Sentry™ Remote Probe Thermometer

Simple one-key operation resets min/max memories and features a high-impact ABS plastic case and a large LCD display that updates every 10 seconds.
  • Triple display constantly shows high, low, and current temperatures
  • Sensor and 10-foot cable may be placed underwater, in refrigerator, or freezer
  • Unplugging the external probe will activate an internal sensor for monitoring ambient temperature
Bottle models (pictured) are supplied with the temperature sensor enclosed in a glycol-filled bottle, protecting it from rapid temperature changes when refrigerator door is opened.
Vaccine vial models  have a sensor probe that is sealed in a 5ml vial filled with nontoxic glycol. The vial mimics vaccine temperature and fits in a vaccine tray.

Instantly view if freezer, water bath, or incubator is within temperature spec. Monitor temperature of any experiment when you’re not there—overnight, weekends, even during lunch. Small cable diameter (1/16-inch) is ideal for applications that require a seal, such as a refrigerator, where a larger cable would interfere with the sealing of the door.

Probe’s wire-mounting bracket permits easy sensor placement. Multi-point calibration on an individually-numbered Traceable® Certificate which assures accuracy from our ISO/IEC 17025:2005 (1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Unit’s high-impact ABS plastic case has a flip-open stand, wall mount, magnet, and Velcro® mounting tape.
