More About This Item

The Traceable® 4735TR Ultra™ Refrigerator/Freezer Thermometer is designed to provide accurate monitoring of refrigerated and frozen storage environments where temperature-sensitive materials such as vaccines, pharmaceuticals, biological samples, reagents, and laboratory supplies are stored.

The included vaccine bottle probe contains a nontoxic glycol solution classified as Generally Recognized as Safe (GRAS) by the FDA. The glycol-filled bottle acts as a temperature buffer, closely simulating the thermal response of stored vaccine products and reducing the influence of temporary air temperature fluctuations caused by door openings or defrost cycles.

Built-in MIN/MAX memory continuously tracks the highest and lowest temperatures recorded, while the large triple-display LCD simultaneously presents current, minimum, and maximum readings. This allows users to quickly assess storage conditions and identify temperature excursions without scrolling through menus.

Audible and visual alarm functions provide immediate notification whenever temperatures exceed user-defined limits. Alarm set points can be configured in 0.1° increments, and alarm indicators remain active until acknowledged to help ensure that critical temperature events are not overlooked.

The 10-foot microcable enables the vaccine bottle probe to remain inside a refrigerator, freezer, incubator, or environmental chamber while the display is mounted conveniently outside the monitored area. Flexible installation options include a flip-open stand, magnetic strips, wall mount, and hook-and-loop mounting strips.

Each Traceable® thermometer includes an individually numbered Traceable® Certificate documenting traceability to SI units through NIST or other recognized National Measurement Institutes (NMIs). Calibration is performed by an A2LA-accredited ISO/IEC 17025 laboratory, supporting healthcare compliance requirements, laboratory accreditation programs, vaccine storage protocols, and quality assurance documentation. Guaranteed to have at least one year of calibration remaining on the certificate.
