Thomas timer counts down from 9999 minutes in one-minute increments. It has a countdown resolution of 1 second for times below 99 minutes.  Users can select an audible alarm or a bright flashing LED visual alarm with the flip of a switch. Automatic memory resets the display to the last programmed time - a very useful feature when performing repetitive tests. A “Thru-zero” feature allows counting down, alarming and then counting back up. To assure accuracy, an individually numbered Traceable® Certificate is provided from an ISO 17025 calibration laboratory accredited by A2LA indicating traceability to NIST standards. Three-eighths inch high digits are readable from 10 feet. Timer measures 3” x 2 1/4” x 3/4” and weighs 3 oz. Timer comes supplied with two AAA batteries, integrated magnet, stand and clip.

Please note: The aforementioned A2LA accreditation belongs to the manufacturer, not Thomas Scientific.
