Vernier reading to 30 seconds of arc. The 175 mm diam. scale is fixed. The table and telescope movements are completely independent of each other and read to 30 seconds of arc using double-ended verniers and magnifiers. Both rotations have fine adjustment screws. Coarse adjustments can also be made by the release of the clamping screw. The collimator is mounted…
Reads to 6 minutes of arc (0.1°) 170 mm diameter metal scale graduated 360° x 1°, independently rotatable, with locking screw, vernier attached to the telescope reads to 0.1° (6 minutes of arc). The collimator is mounted on a fixed pillar, with an achromatic objective of 150 mm focal length and 21 mm aperture, and has an adjustable slit 6…
Made of glass, 26 cm long overall, narrowed to capillary width for 8.5 to 10 cm of length. Metal wires holding the electrodes are sealed through the ends and welded to metal caps, which have loops for connecting wires. For use with Spectrum Tube Power supply PH61025.
The set consists of three rugged, sealed, transparent plastic tubes containing colored fluids of three different viscosities. The bubble in each tube rises at a constant speed which depends on the type of fluid, the angle at which the tube is inclined, and to some extent the temperature. Students track the time it takes for an air bubble to move…
Transparent plastic body. Each scale has been individually calibrated and equipped with a high grade spring with adjustable zero. High contrast marking make readings easy. Plated steel suspension ring at top and hook at bottom.
In the robust plastic transparent body, overall length 285 mm approx. with upper & lower suspension hooks, with zero adjustments, scales are both in grams and Newton.
A set of 5 springs with different spring constants (k)- stretch by 2cm with a load of 0.5N, 1, N, 2N, 3N, and 5N respectively. Prestress has been removed for accurate results. With a hook to support the weight hanger and a red arrow to indicate positions. Ages 13+
This student force table is a complete set with these new features: -Dual scale that allows students to take readings either clockwise or counterclockwise; Four complete weight sets (each contains 2 of 5g, 4 of 10g, 4 of 20g brass slotted weights and a 20g brass weight hanger), four pulleys with clamps and two sets of strings that allows students…
