HORIBA OBS-ONE GS Unit
详细介绍
概要
OBS-ONE 是最新的便携式排放测量系统，专为实际道路条件下的发动机/车辆认证而设计。
它测量排放浓度（CO，CO2，THC，氮氧化物，NO2），颗粒物，空气与燃料比，排气流速率，GPS数据，环境条件（大气温度，湿度和压力），并计算质量排放。
OBS-ONE 采用了高度适应的智能操作平台"HORIBA ONE 平台"，该平台集成了其他 ONE 系列产品数据，优化了测试单元操作。
HORIBA 已开发了广泛的排放测试应用程序，用于认证和发动机/车辆 R&D，例如使用测试自动化系统-STARS 模拟测试单元中的真实驾驶事件。此模拟需要从 OBS-ONE 和驱动器记录器中组合数据。
