详细说明：
电子Von Frey触痛仪用来评估机械痛（阈值）， “Supertips?” (软头) 用来检测all的感官阈测试。2390系列支持研究人员在单体内使用三种探针。Von Frey触痛仪支持多个用户用一个单体做多个研究。我们的仪器投入市场已超过十年，是弟一台能wu污染的准确检测并能自动记录痛阈的仪器。操作方便，设计紧凑。电子Von Frey触痛仪提供的探针有90g、800 g和1000g三种规格。探针的类型视实验对象而定。
硬头的用于痛阈的实验；Supertips?用于感观阈的实验。本公司的测试丝设计dute——每个软头的末端直径为0.8mm ，可以有效的消除误读的情况发生。（误读的原因是由测试丝的薄厚不均造成的）。仪器具有测量、存储和显示功能，免除了手算的繁琐。
实验简便：选择合适的原件放在探针上，插进实验对象，根据实验对象的反应，仪器就能快速的显示出结果并储存。 作为核心原件的内置传感器固定在元件上，并和电子系统相连，以便记录数据。
all的电子测痛仪已在出厂前校准完毕，不再需要购买任何的校准设备。 模拟输出线（可选）可提供一个模拟输出的电压，它和施加的压力成正比。信号du立，可用于表格记录或者AD转换器。
电子Von Frey触痛仪操作简单方便，改进了传统的枪头末端，不仅可以进行痛阈实验，同时还可以进行感官阈的实验。
什么是 “Supertips?”
原来的论文撰写者都提到电子Von Frey触痛仪的测试丝的直径不均是个严重的问题。有专利技术的 “Supertips?” 15根不同的检测丝直径都在0.8mm ，具有极度的均一性。
这种技术只有本公司公司的电子测痛仪才有这种特性。探针尺寸不再是影响痛阈或者压力阈的因素，实验结果终于可以比对！均可单du预订。
电子Von Frey触痛仪由于枪头末端的吸湿性能消除wu效数据收集(实验证明：在相对湿度28-52%的变化可能导致压力高达100%的变化！)只有读数器准确才能读出准确的数值。任何情况下不同程度的弯曲能改变20-30%的数值，这个通过读数器可以看出来。柔韧的枪头末端的天然抗折力有很大的优势。不需要上下来回的找起点。如果不使用外接电源，电池寿命为50小时
电子Von Frey测痛仪特点：
? 适用MRI探针
? 单体内可插入三个探针
? LCD 显示屏 (Floating or last max. & minimum)
? 硬枪头能达 800 Gr.
? “Supertips?” 从15 到65Gr.
? 适用1K探针
? 电子微处理器0.1Gr插入式探针
? 防潮
? 隔温
? 可选的模拟输出线
? 吸头可根据情况定制
? 具有测量、存储和显示功能，免除了手算的繁琐。
? 可以预设和选择zui大限额，能鲸准到1g，当到预设的限额时，警示灯会通知使用人员。
? 实验简便：选择合适的原件放在探针上，插进实验对象，根据实验对象的反应，仪器就能快速的显示出结果并储存。
? 作为核心原件的内置传感器固定在元件上，并和电子系统相连，以便记录数据。all的电子测痛仪已在出厂前校准完毕，不再需要购买任何的校准设备。
