nMeasuring gas range
Select the range for the sample gas selected under "Measuring Component". Select "None
(-NN)" for gases not included in the measurement component. This product is free-range. You
can set the range within the selected measurement range. The measurement accuracy varies
when the measurement range is set within the optional range. For details, refer to the general
specicationGS11G06A01-01EN.
For multi-component meters, the measurement ranges for NO/SO2/CO/CH4measurement
cannot be combined with "-E□" and "-P□" together.
(Example) Measuring component code - B1 (NO+SO2meter)
NO measurement range: -E3 (0-200/2000 ppm), SO2measurement range: -E6 (0-500/5000 ppm)
=> Both are -E ranges, so they can be combined.
NO measurement range: -E3 (0-200/2000 ppm), SO2measurement range: -P1
=> Not possible due to a mix of -E and -P ranges
/U: See Table 3 for unit conversion options.

Figure 1 Maintenance space
To install the analyzer for optimum performance, select a location that meets the following
conditions;
• IR800G/IR810G is system built-in type, embedded in a steel rack, or enclosure of steel
sheet.
Keep a minimum clearance of 10 cm above the analyzer for heat dissipation. The same
size of clearance is required for each analyzer when you install several units on a multistage
rack.
• Install the external switch or the Circuit breaker in the same room where the IR800G/
IR810G is installed. Place it where the operator can access and indicate that it is the power
switch of the IR800G/IR810G.
