Description

Small-size wireless thermometer and contain its wireless temperature measurement system Technical Field The utility model belongs to the field of temperature measurement, and particularly relates to a small wireless thermometer and a wireless temperature measurement system comprising the same. Background In the related art, a small-caliber container, such as a headspace bottle, a vaccine/medicine cold chain transport bottle, a bioreactor/cell culture bottle and the like, needs to be in a sealed state in the use process and monitor the internal temperature in real time so as to ensure the accuracy of detection results of related experiments related to the container, the effectiveness of objects contained in the container and the quality of objects cultured by the container. Generally, the ideal temperature measurement mode of the small-caliber container adopts a built-in wireless temperature measuring instrument, and the built-in wireless temperature measuring instrument is adopted, so that the container does not need to be perforated, the tightness of the container can be ensured, the internal temperature of the container can be directly measured, and the temperature measurement result is accurate. However, the existing built-in wireless thermo-detector often cannot meet the size requirement of the small-caliber container on the built-in wireless thermo-detector due to the self structural design, namely, the built-in wireless thermo-detector cannot enter the small-caliber container through the small port of the small-caliber container due to oversized size.
