The ultimate multifunction laboratory timer for all your timing requirements, with built-in experiments and a large LCD screen display. No computer is needed – unless you want to paste the results into a Word document or spreadsheet, in which case a USB lead is all that?s needed (no software required).Designed by the makers of LogIT, it is simple and intuitive to use, with helpful on-screen prompts telling you how to set things up. Suitable for use with all age groups, the number of decimal places can even be set to suit age and ability. Powered by a single, replaceable, PP3 battery (included), Time Machine will run for months of classroom use before the battery needs replacing.Many physics experiments are based around time. Time Machine was designed to perform time related tasks easily in a quick, intuitive way without the need for a computer.A range of accessories are available to use with the Time Machine, allowing you to perform experiments in: Reaction Timing; Speed; Acceleration; Speed of Sound; Frequency Count; RPM; Simple Harmonic Motion (SHM); Acceleration Due To Gravity (?g? by freefall); Lap Timer. Or you can simply use Time Machine on its own as a stopwatch or countdown timer.
