The invention relates to the field of emergency rescue, in particular to a portable rapid tester for the absorption rate of calcium hydroxide. The problems that an existing calcium hydroxide absorptivity testing method is long in testing time, complex in procedure, poor in accuracy and the like are solved. The calcium hydroxide absorptivity testing device comprises a pretreatment device used for polishing a testing sample, an absorptivity rapid detection system used for detection, a display and calibration module used for displaying data and a power supply module used for supplying power to the structure. The rapid absorption rate detection system comprises a sound wave exciter, a sample clamping and sound wave testing device, a low-noise signal line, a sound signal processor, a data converter and a displacement signal processor. According to the invention, the test time is extremely short, the test result precision can be controlled within 1%, the test and maintenance difficulty is low, and an operator can q
