The invention relates to a portable chemical reaction heat measuring device and a measuring method.The portable chemical reaction heat measuring device comprises a shell, a temperature control and calorimetric device, a weight testing device, a sample injection structure, a control structure and a leakage-proof connector, the temperature control and calorimetric device comprises a temperature sensor, a testing container and a reference container, and the testing container and the reference container are arranged in the shell in parallel; the temperature sensor measures temperature changes and sends data to the control structure, the weight testing device is arranged below the testing container, monitors and records weight changes of materials and sends data to the control structure, the sample injection structure is communicated with the testing container through a leakage-proof connector and provides samples, and the pressure sensor is arranged on the outer side of the testing container and used for detecting the temperature changes of the materials. And a reaction heat calculation program is also arranged in the control structure. By adopting the calorimetric equipment, the reaction heat test can be directly carried out on the production site, and by virtue of a specific sample introduction structure and a weighing system, not only can materials be prevented from being contacted with the outside, but also the input material quantity can be accurately weighed.
