IITC 钳式测痛仪是根据 Randall-Selitto 理论设计，是进行炎症足加压实验的经典仪器。

型号2450型

根据 Randall-Selitto 法，将药物添加在小实验动物的炎症足上。Randall-Selitto 测痛仪测量单元具有压力传感器，并通过液晶屏实时显示测量参数。压力施加器一端为弹性的尖形探头，另一端平坦。使用时将动物足部放入压力施加器中间，对准探头，施加压力。逐步提高作用于动物爪子上的机械压力，逼近动物的疼痛阈限，当动物出现缩足反应时，仪器自动测量并记录压力信号，以g为单位。

与热痛不同，该仪器用于机械压痛和钝痛的痛觉测量，常用于辨别左右爪不同的痛觉反应。

钳式测痛仪的产品特点

钳式测痛仪 Rodent Pincher Analgesia Meter 

Rodent Pincher allows researchers to measure and test pain threshold in a simple, accurate method when measuring pain nociception.

The system can be used on mice or rats and will measure and display in grams the amount of force that has been applied to the animals paw.

Accuracy is .01 grams, no calibration needed.

One year warranty, CE certified
