More About This Item

The Traceable® 5045TR is a versatile digital timer designed to support precise timing requirements across a wide range of professional applications. Its compact size and lightweight construction make it easy to carry in a pocket, attach to a key ring, clip onto clothing, or mount to metal surfaces using the included magnet.

The timer can be programmed in countdown mode from 1 second up to 99 hours, 59 minutes, and 59 seconds in one-second increments, making it suitable for long-duration experiments, incubation periods, manufacturing processes, cooking applications, and routine laboratory procedures.

In stopwatch mode, the timer counts upward from one second to 99 hours before repeating, providing a convenient solution for tracking elapsed time in testing, inspections, process monitoring, and research activities. Time-out functionality is available in both count-up and count-down modes for increased flexibility.

The large LCD display with 1/3-inch-high digits provides clear readability, while the five-key control layout enables quick operation with minimal training. The durable ABS plastic housing offers chemical resistance for demanding laboratory and industrial environments.

Each Traceable® timer 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, helping support laboratory accreditation requirements, quality assurance programs, regulatory compliance, and audit documentation. Guaranteed to have at least one year of calibration remaining on the certificate.
