A simple, inexpensive computer interface designed for in vitro or in vivo researchers with limited electronic experience allows direct on-line multi-channel temperature recording from thermistor probes to any micro-computer. The designed system saves time and increases the accuracy of collected data that are ready for storage in files compatible with graphic and statistical software. In vitro testing of the designed interface, over a range of 25-45 degrees C, showed a 0.999 intraclass correlation to reference water bath temperatures. In vivo testing using anesthetized rats involved simultaneous measurements of: (1) a thermogenic tissue, interscapular brown adipose temperature (IBAT), (2) core (colonic) temperature, and (3) surface (tail) temperature, a heat loss tissue. The temperatures measured by the designed computer-interface demonstrate excellent stability, sensitivity and accuracy when compared to respective temperatures measured by a YSI telethermometer.
一种为电子经验有限的体外或体内研究人员设计的简单、廉价的计算机接口，可将热敏电阻探头的多通道温度直接在线记录到任何微型计算机上。该设计系统节省了时间，提高了所收集数据的准确性，这些数据可随时存储在与图形和统计软件兼容的文件中。在25-45摄氏度范围内对设计的接口进行体外测试，结果显示与参考水浴温度的组内相关系数为0.999。使用麻醉大鼠进行的体内测试涉及同时测量：（1）产热组织，肩胛间棕色脂肪温度（IBAT），（2）核心（结肠）温度，以及（3）表面（尾部）温度，一种散热组织。与YSI遥测温度计测量的相应温度相比，由设计的计算机接口测量的温度显示出极佳的稳定性、灵敏度和准确性。
