Calculated Industries 9130 TimeMaster II

A versatile, easy-to-use time-math calculator for conversions, schedules, rate-based estimates, and solving elapsed time calculations, the TimeMaster II calculator (model 9130) from Calculated Industries can instantly resolve time-based costs and rates for billing and estimates. And in case you are in the broadcasting industry, you’ll be able to use the time and stopwatch keys for accurate production and editing. Additionally it is ideal for pilots and flight attendants for computing flying hours in addition to athletes and coaches for tracking performance and elapsed times.

The time-math measurement and conversion functions can calculate down to 1/100 of a second, and along with hours, minutes, and seconds the TimeMaster II can calculate a couple of days. The easy-to-use stopwatch offers count-down and count-up functions in addition to a split/lap with an optional buzzer. Other features include a rate function for time-based billing and estimates, a “paperless” tape that allows you to review the previous 20 entries, and memories to store up to 10 separate values.

The TimeMaster II comes with an ergonomically designed shock-, moisture- and dust-resistant Armadillo Gear case with a soft grip that helps to keep it from slipping out of your hand. Measuring 5.5 x 3 x 0.5 inches, it weighs 3.2 ounces by itself or 6.7 ounces when placed in its Armadillo Gear Case. It’s powered by a single 3-volt lithium battery (CR2032), and it’s backed by a one-year limited warranty.
