Spark timer is used for measuring velocity and acceleration of falling or moving objects. When the tape is pulled through the timer a spark is created which burns tiny dots in the tape at a precise and same interval. The faster the tape is pulled through the timer the larger the distance between the...

A fine instrument for determining the radius of curvature of spherical surfaces such as mirrors and lenses. Its micrometer screw is graduated to measure displacement as small as 0.01mm. The instrument has two brass plates and three steel legs. A flat glass plate is provided for support while taking...

This measuring set contains four high quality instruments-a 0-25 x 0.01 MM micrometer caliper, a 90 degree knife edge square, a 150 x 0.05 MM vernier caliper, and a 150 MM steel ruler. All of these are housed in a sturdy plastic storage case.

These spring scales feature a clear plastic tube design, and are color-coded. A zero adjustment screw is provided at the top. Overall length approx.7".

Easily determine the height of an object by using angles. This clinometer has a spring-loaded trigger that holds a pivoting arm stationary to indicate the angle above or below the horizon. The maximum angle above or below the horizon is 70°. This can be used for measuring the height of trees,...

The clear plastic 6" / 15cm ruler is scaled in 1mm increments on one side.

Ammeters are used to measure the current flowing through a circuit. Current is measured in amperes, which is denoted by A on our meters. Our meters are accurate to +/- 2.5% and have banana jack style binding posts. This AC/DC ammeter can measure a range of 0A to 3A.

Constructed of anodized aluminum, with steel hooks, this spring scale is extremely durable. Available in seven color-coded sizes.

Hardwood half meter stick for use with our Demonstration Balance Support or other laboratory measurement activities.

This is replacement tape for the Spark Timer (TKTMR). The Spark Timer is a recording device used to measure the velocity and acceleration of a falling or moving object. It sparks at uniform intervals, leaving marks on a paper tape. The distance between the marks on the tape are used to calculate...
