Horiba PG250/350 Portable Gas Analyzer

Horiba PG250/350 Portable Gas Analyzer

Pine Item #54368

This latest gas analyzer is both portable and MCERTS approved.  Capable of measuring five components, the Horiba PG-250 and the PG-350 is a highly reliable and versatile gas analyzer for compliance testing of NOx, SO2, CO, CO2, and O2.

Housed in a single lightweight and fully portable case, it utilizes the same measurement principles as permanently installed CEMS - unlike other portable gas analyzers that rely upon electro-chemical sensors.


The NOX detector uses a Cross-flow modulation chemiluminescence detection; the SO2 and CO detector operate with a Cross-flow modulation Non-dispersive infrared (NDIR) absorption method; the CO2 unit uses the standard Non-dispersive infrared (NDIR) absorption method; and the O2 unit uses the paramagnetic method for exclusively in EU area.

Cross-flow modulation method requires no optical adjustments as dual optical path measurement does because sample gas and reference gas flow into a single measurement cell switching one by one. Since clean air is fed into the sample cell in between each batch of sample gas the cell remains clean which reduces the span drift and keeps long-time stability.

Ease of operation ensured by high visibility color LCD touch screen. The useful functions such as screen capture trend graph or operation guide etc. can be executed on the screen.

Reducing warm-up time in half the PG-350E is ready to measure within 30 minutes. Moreover the timer function sets up an automated warming-up according to Your time settings.

98% efficiency of NOX-convertor enables more precision measurement.

Energy efficiency rises up to 35% by reduced power consumption compared to our previous models.

A SD memory card slot is installed in the front panel and quick data saving is available. Ethernet interface for connection to a LAN environment enables real-time data import over the network.
