Thomson hadn't an instrument; this model is only a hypothesis.
JJ Thomson called his model of the atom the "plum pudding model." In this model, electrons were embedded in a positively charged sphere, resembling the distribution of plums within a British pudding dessert.
You can find a drawing of Thomson's model of the atom in most chemistry textbooks or online sources that discuss the history of atomic models. The model, also known as the "plum pudding model," depicts the atom as a positively charged sphere with negatively charged electrons embedded within it like raisins in a cake.
Joseph J. Thomson's postulates included the idea that electrons are negatively charged particles, they have a much smaller mass compared to atoms, and they are uniformly distributed within the atom. These postulates were part of Thomson's plum pudding model of the atom.
In 1897 J.J. Thomson discovered the electron by experimenting with a cathode ray tube.
The Thomson atomic model is referred to as the blueberry muffin or plum pudding model. The name is derived from the visual interpretation that an atom is a circle with electrons arranged non-randomly in rotating rings. The electron placement is said to resemble the raisins in plum pudding or the berries in a muffin.
The plum pudding model by JJ Thomson.
Thomson is responsible for discovering that an atom contains electrons.
JJ Thomson called his model of the atom the plum pudding model.
J.J. Thomson discovered the electron and proposed the plum-pudding model for the atom.

Dalton described atoms as solid spheres. Thomson discovered the the atom also contained negatively charged particles called electrons distributed in such a way that the atom had no charge.
