GENERAL 概述

Unique sal领 points 特点

Ø Since more than 60 years HORIBA provides his own analyzers and boards and guarantees the availability of spare parts at least 10 years after discontinuation.

拥有超过 60 年历史的 HORIBA，所有分析单元均为 HORIBA 生产制造，可以保证分析

仪及其零部件的供应，完全有能力保证在设备停产后至少 10 年的备件供应

Ø Using many common parts of MEXA-ONE, MEXA-7000 and OBS-2000. No need to re-acquire parts for OBS-ONE. This means lower operating costs.

与 MEXA-ONE, MEXA-7000 和 OBS-2000 很多零件可以共用，从而降低使用成本。

Ø Pitot pressure method of measuring the volume flow. By means of very rapid pressure sensors of flow, especially at idle, is exactly measured and calculated (HORIBA patent).

采用 HORIBA ZG技术的新型皮托管压力法测量汽车排气流量，怠速时排气流量的测

量精度也可以得到保证。

Ø No cooler, therefore shorter response times.

没有冷凝器，可以缩短响应时间。

Ø Semi-vacuum-type analyzers. Reduction of the heated zones by means of a cold and lighter pump and. Power consumption 200W (LDV) and thus longer run time with one battery charge.

半真空式分析仪。通过降低了加热区域， 使得动力消耗更节省， 功率小于 200W

（LDV）。电池一次充电后可以设备运行时间更长。

Ø Hot and wet measurement of components (HORIBA patent). Direct water correction by simultaneous measurement of water.

所有分析单元采用加热湿式分析单元（HORIBA ZG）。并且测量出排气中的水的浓度，

用于修正 CO/CO2/THC/NOx 的测量结果，使测量结果更准确，精度更高。

Ø A CLD is very good in the low concentration range (ppb) and conform to regulation. Direct compensation of the CO2 and H2O concentrations. Without cooler no loss of N2O. Required ozone is generated from the ambient air.

HORIBA CLD 在低浓度（ppb）时也有非常好的测试精度，并且采用 CO2 和 H2O 浓度

进行修正。由于没有冷凝器，因此对于 N2O 也没有损失。测量过程中所需要的 O3 由

设备采用空气生成，因此无需额外配备 O2 气体

Ø All data for the post-processing is stored in OBS ONE. Even if the contact with the control-PC gets lost, the data is still present.

所有后处理的数据可以储存在 OBS-ONE 主机中，即便控制电脑丢失或损坏，数据依然

得到保护。
