PG-300 series

Portable Gas Analyzer

The PG-300 is a compact and lightweight stack gas analyzer that can simultaneously measure up to five separate gas components. Its capability of providing precise measurement has been proven for field measurements and also for laboratory applications. The PG-300 series also offers the capability to measure methane (CH₄). A 20% weight reduction over previous PG models and integration of shock-resistant side guards make the PG-300 a robust analyzer for use in the field. An optional electronic cooler unit is available for long-term measurements for severe monitoring applications as gas turbines, boilers, and incinerators PG-300 series versatility makes the analyzers suitable for investigating environmental problems, evaluating catalyst performance, and for controlling process gas streams.

The NOx analysis unit uses a Cross-flow modulation chemiluminescence detection method; the SO₂, CO, and CH₄ units use a Cross-flow modulation Non-dispersive infrared (NDIR) absorption method; CO₂ unit uses standard Non-dispersive infrared (NDIR) absorption method; and the O₂ unit uses zironia method, galvanic method, and paramagnetic method for exclusively in EU area. PG-300 is comparable to large-scale, specialized units in terms of accuracy and offers a high degree of selectivity in analysis.
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.
New methane (CH₄) analyzer models are suitable for expanded application such as biomas combustion or fuel cell.
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, PG-300 is ready to measure in 30 minutes. Moreover, timer function let the equipment start warming-up automatically at your setting time. Combination of these advanced functions offer time saving for readiness and efficient measurements.
The 95% efficiency of NOx convertor enables the more precision measurement.
Energy efficient with up to 35% reduction in power consumption compared to our previous models.
A SD^TM 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.
