DS1921H：高分辨率、Thermochron iButton器件
Thermochron® iButton®器件(DS1921H/Z)是一种牢固、配备齐全的系统，可以测量温度并将结果记录于保护的存储区。记录速率由用户定义，可以按温度值直接存储，也可以以柱状图形式存储。该器件可存储多达2048个、1至255分钟等间隔时间的测量温度值。柱状图以0.5°C的分辨率提供64个数据箱。如果温度超出用户设定的范围，DS1921H/Z也会记录何时发生时、温度超出允许范围的持续时间、以及温度是过高还是过低。辅助的512字节读/写NV存储器可存储属于与DS1921H/Z相联系的对象信息。数据通过1-Wire®协议串行传输，仅需要单个数据线和返回地线。每个DS1921H/Z都有工厂激光刻度的、保证唯一的64位注册号，以实现产品跟踪。坚固耐用的不锈钢封装可防尘、防潮、防震。各种附件允许DS1921H/Z安装在几乎任何物体上，包括容器、托盘和袋子。
