Precision dynamometer
1.5 N 0.1 N 16 cm
3.0 N 0.1 N 16 cm
In strong plastic sheath, with stop to prevent excessive extension of the
spring. With zero-point slide adjustment to compensate for the weights of
accessories required for the experiment, e.g. balance pans or pulleys. The
scale is easily readable, as it consists of alternative red and white divisions,
each containing 10 marking divisions.
