A titration module includes a base, at least one titration unit, a contact angle measuring module, and a computing unit. The at least one titration unit is disposed above the base for titrating a globule onto a device under test. The contact angle measurement module is disposed above the base for measuring a first height and a first radius of the globule. The computing unit can calculate a second radius according to the first height and the first radius, and can calculate a contact angle of the globule according to the first height and the second radius. Also disclosed are a test apparatus, and a method for measuring titration contact angles.
