Horiba PG-350E Portable Gas Analyzer Horiba Get Quote



The PG-350E achieves measurement performance equal to laboratory equipment in a highly portable package. As part of the PG-300 series, the PG-350E is a compact stack gas analyzer that can simultaneously measure up to five separate gas components. The approximately 20% lighter body from the previous PG-250-model is optionally protected by rugged side guards, which prevent the analyzer from shocks and damages. PG-350E covers NOX, SO2, CO, CO2 and O2 - measurement and is operating according to: DIN EN 15267 - 3, DIN EN 14181 and
approved as Standard Reference Method (SRM) for:
CO (DIN EN 15058)
O2 (DIN EN 14789)
NOX (DIN EN 14792)

The field conscious design supports whatever the measurement scene is. An optional electronic cooler unit is available for long-term measurement under tough environments such as gas turbines, boilers, and incinerators facilities.


Key Features

  • Multi-language software setting menu: English, German, French, Russian
  • 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.
  • Energy efficiency rises up to 35% by reduced power consumption compared to our previous models.
  • 98% efficiency of NOX-convertor enables more precision measurement.
  • 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.
  • 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.
  • 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.
  • Certification: TÜV(EU)
  • 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.
