Product Details

The 4733TR Ultra™ Refrigerator/Freezer Thermometer is designed for continuous monitoring of temperature-sensitive storage environments. Its dual-channel design enables simultaneous measurement of two refrigerators, freezers, incubators, water baths, or separate locations within the same chamber.

The included submersible bullet probes are suitable for monitoring air and liquid temperatures. Their compact size and durable construction make them ideal for laboratory, healthcare, pharmaceutical, and environmental monitoring applications.

The LCD display shows current, minimum, and maximum temperatures, allowing users to quickly identify temperature trends and excursions. Built-in Min/Max memory supports compliance documentation and routine monitoring programs.

Audible and visual alarms notify users when temperatures exceed programmed limits. Alarm settings can be adjusted in 0.1° increments for precise control, and alerts remain active until manually acknowledged to help ensure critical events are not missed.

The 10-ft probe cables allow sensors to remain inside monitored equipment while doors close securely. Multiple mounting options, including a stand, magnetic strips, wall mounting, and hook-and-loop fasteners, provide installation flexibility.

Each unit 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.
