Traceable® 4732TR Ultra Calibrated Refrigerator/Freezer Thermometer; 1 Bullet Probe

Traceable® 4732TR Ultra Calibrated Refrigerator/Freezer Thermometer; 1 Bullet Probe

The Traceable® Ultra Calibrated Refrigerator/Freezer Thermometer provides high‑accuracy temperature monitoring with Ultra™ performance of ±0.5°C between –30 to 50°C. Featuring a rugged bullet probe, triple‑display functionality, and NIST‑traceable calibration, it is ideal for refrigerators, freezers, incubators, and water baths requiring precise, continuous monitoring.

Key Features

• Ultra™ accuracy ±0.5°C between –30 to 50°C; otherwise ±1°C
• Triple display shows MIN, MAX, and current temperature simultaneously
• 10‑ft microcable allows refrigerator/freezer doors to close on it
• Selectable °C/°F units
• One bullet probe for air and liquid measurements
• Probe and cable are fully submersible
• Includes NIST‑traceable certificate from A2LA accredited (1750.01) calibration laboratory
• 1‑year warranty

More About This Item

Designed for critical cold‑storage environments, this Ultra™ thermometer provides accurate monitoring from –50 to 70°C (–58 to 158°F) with 0.1° resolution. The triple‑display shows current, minimum, and maximum temperatures at a glance, making it ideal for overnight or long‑term monitoring.

Built‑in audible and visual alarms activate when temperatures rise above or fall below user‑defined set points. Alarm thresholds are adjustable in 0.1° increments. Both alarm types continue to alert even if the temperature returns to normal conditions until the alarm is acknowledged.

The bullet probe is designed for both air and liquid measurements, and its submersible construction ensures durability in water baths and wet environments. The 10‑ft microcable allows refrigerator or freezer doors to close securely around it without compromising the seal.

Each Traceable® instrument includes an individually numbered Traceable® Certificate verifying accuracy from our ISO/IEC 17025:2017 (1750.01) calibration laboratory, accredited by A2LA. Measurements are traceable to SI units through NIST or other recognized national measurement institutes (NMIs) that are signatories to the CIPM Mutual Recognition Agreement. This eliminates the need for separate calibration, saving time and cost.
