Product Details

The 4731TR Ultra™ Refrigerator/Freezer Thermometer is designed for temperature-sensitive storage applications where accurate monitoring is critical. Its dual-channel design allows simultaneous monitoring of two separate locations, such as refrigerators, freezers, incubators, water baths, or environmental chambers.

The included glass bottle probes are filled with nontoxic glycol solution that buffers rapid air temperature changes caused by door openings or equipment cycling. This provides a more representative indication of actual product temperature for vaccines, pharmaceuticals, biological samples, reagents, and other sensitive materials.

The large LCD display continuously shows current, minimum, and maximum temperatures, making it easy to identify temperature excursions and review storage conditions. Built-in Min/Max memory supports quality assurance and compliance monitoring programs.

Programmable audible and visual alarms notify users whenever temperatures exceed established limits. Alarm indicators remain active until manually acknowledged, helping ensure critical events are not missed.

The 10-ft probe cables allow bottle probes to remain inside monitored equipment while the display stays mounted externally. Multiple mounting options include a stand, wall mount, magnetic strips, and hook-and-loop fasteners.

Each thermometer includes an individually numbered Traceable® Certificate documenting traceability to recognized national measurement standards. Guaranteed to have at least one year of calibration remaining on the certificate.
