GENERAL 概述

Unique salling points 特點(diǎn)

? 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.

擁有超過(guò) 60 年歷史的 HORIBA，所有分析單元均為 HORIBA 生產(chǎn)制造，可以保證分析

儀及其零部件的供應(yīng)，完全有能力保證在設(shè)備停產(chǎn)后至少 10 年的備件供應(yīng)

? 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.

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

? 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 專利技術(shù)的新型皮托管壓力法測(cè)量汽車排氣流量，怠速時(shí)排氣流量的測(cè)

量精度也可以得到保證。

? No cooler, therefore shorter response times.

沒(méi)有冷凝器，可以縮短響應(yīng)時(shí)間。

? 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.

半真空式分析儀。通過(guò)降低了加熱區(qū)域， 使得動(dòng)力消耗更節(jié)省， 功率小于 200W

（LDV）。電池一次充電后可以設(shè)備運(yùn)行時(shí)間更長(zhǎng)。

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

所有分析單元采用加熱濕式分析單元（HORIBA 專利）。并且測(cè)量出排氣中的水的濃度，

用于修正 CO/CO2/THC/NOx 的測(cè)量結(jié)果，使測(cè)量結(jié)果更準(zhǔn)確，精度更高。

? 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 在低濃度（ppb）時(shí)也有非常好的測(cè)試精度，并且采用 CO2 和 H2O 濃度

進(jìn)行修正。由于沒(méi)有冷凝器，因此對(duì)于 N2O 也沒(méi)有損失。測(cè)量過(guò)程中所需要的 O3 由

設(shè)備采用空氣生成，因此無(wú)需額外配備 O2 氣體

? 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.

所有后處理的數(shù)據(jù)可以儲(chǔ)存在 OBS-ONE 主機(jī)中，即便控制電腦丟失或損壞，數(shù)據(jù)依然

得到保護(hù)。
