Sper Scientific* Large Display Bench Timers

Although small and easily portable, this timer features a large display with ³/₄ in. high digits. Also unique is an auto-power-off feature to extend battery life (operates only when the timer is idle for 10 minutes and will not interrupt a timing sequence). Counts down from 100 minutes with 1-second resolution. Short warning alarms sound at 3 and 5 minutes prior to the final 30-second alarm. Automatically records elapsed time following the alarm for up for to 20 minutes, or until stopped. A memory recalls the last timer setting for repetitive tests. Has a built in stand, pocket clip and magnetic back. One AAA battery included. Catalog No. 350-35665 includes a NIST traceable certificate of compliance.
