The Horiba PG-250 is a portable multi-gas analyzer that can monitor up to 5 components: NOx, SO2, CO, CO2, and O2. It utilizes the same measurement principles as permanently installed CEMS. The instrument directly interfaces with a laptop and features built-in sample conditioning. An optional auxiliary cooler is available to condition samples with excess water vapor.

1. Horiba PG-250
Portable Multi-Gas Analyser
The Horiba PG-250 is a highly reliable and
versatile gas analyser for compliance testing of
NOx, SO2, CO, CO2, and O2.
MCERTS approved portable stack testing
Unlike other portable gas analysers that rely upon electrochemical
KEYBENEFITS
•
sensors, the Horiba PG-250 utilises the same measurement principles as a
Compact and lightweight housing
with a built in carrying case so it is
permanently installed CEMS. The PG-250 is ideal for CEMS certification
testing or for use when stack gas emissions must be monitored
periodically at one or multiple stacks.
ideal for moving between stacks
•
Large, easy to read front panel
Direct readings on-site
displays
•
The instrument can interface directly with a laptop computer through
A single portable analyser capable
of measuring five components
an RS-232C interface to record measured values.
Sample conditioning
The Horiba features a built-in sample conditioning system with
sample pump,filters, and a thermoelectric cooler. An optional auxiliary
thermoelectric pre-cooler (PS-200) is available to condition samples

PRODUCT OVERVIEW
separate sample gas streams
Accurate measurements of gases require gas
samples with stable dew points even under
harsh ambient conditions
The Buhler Cooler is available for hire through a1-cbiss, it is
typically used in application with Horiba PG-250. The EGK
models from Buhler provide a compressor-type cooling
system connected to a cooling block. The temperature of
the cooling block is regulated by the Buhler Constant
dual stream heat exchanger hence the cooler may serve two
