甩尾测痛仪测量大鼠对辐射能反应时间，辐射来自150瓦光源。甩尾测痛仪使用一台抛物面反射器将射线集中于大鼠尾。光源的能量可以调节并能够显示能源利用的百分率。为镇痛药物疗效迅速出现多使用大鼠.

甩尾测痛仪  的详细介绍  

甩尾测痛仪测量大鼠对辐射能反应时间，辐射来自150瓦光源。使用一台抛物面反射器将射线集中于大鼠的尾巴。光源的能量可以调节并能够显示能源利用的百分率。为镇痛药物疗效迅速出现多使用大鼠.

光学传感器置于聚焦的光源之下。鼠应该放置在合适的位置上，使它的尾巴遮暗从传感器聚焦的光源。 当系统开始时，使用提供的脚踏开关或面板上的启动键，光源照亮和计时器以十分之一的秒速度计数。 当大鼠 的尾开始甩动时，表明它的痛苦开始，漏出传感器。甩尾运动关闭了计时器和光源。 反应时间可直接地从显示器上读取，精确到秒或十分之一秒 。一个标准并行端口允许与打印机的连接记录试验数据、能级和反应时间。 定标设施允许在开始实验之前将光源设置到期望水平。

This meter measures a rat’s reaction time to radiant energy,from a 150 watt light source. The beam is focused on its tail usinga parabolic reflector. The energy of the light source can beadjusted and the display indicates, as a percentage, how muchenergy is being utilized

An opticalsensor is located underneath the focused light source. The ratshould be positioned such that its tail obscures the focused lightsource from the sensor. When the system is started, either usingthe supplied footswitch or front panel mounted start key the lightsource illuminates and a timer starts counting in tenths of asecond. When the rat’s tail flicks, indicating its pain threshold,it uncovers the sensor. This tail movement turns off the timer andlight source. Reaction time can be read directly from the displayin seconds and tenths of a second.
A standard parallel port permits connection to a printer to recordthe trial number, energy level and reaction time. A calibrationfacility allows the light source to be set to the desired levelbefore commencing with the experiment.
