随着科学技术的不断发展,特别是近年来计算机科学越来越广泛地应用,记录各种瞬变或缓变信息的自动仪器成为必不可少的工具。笔式记录仪(又称笔录仪或描笔记录仪)是各种类型的自动记录仪中的一种。它既可做单点记录,又可做多点记录,不仅能记录缓慢的电流、电压等信息,而且能记录速度较快的各种参量,如振动、应力、应变、心电、脑电等信息,是测量工业参数、记录生物医用信息 With the continuous development of science and technology, especially in recent years computer science is more and more widely used, it is an indispensable tool to record all kinds of transient or slow information automatic instruments. Pen recorder (also known as pen recorder or pen recorder) is one of various types of automatic recorder. It not only can do single point record, but also do multi-point record, not only can record slow current, voltage and other information, but also can record various parameters such as vibration, stress, strain, ECG, EEG Information, is to measure industrial parameters, record biomedical information
