Description
Yokogawa Separate type Zirconia Oxygen Analyzer
ZR22G/ZR402G
Yokogawa Oxygen Analyzer ZR22G/ZR402G
Yokogawa's zirconia oxygen analyzers are used for combustion monitoring and control in a wide
variety of applications and help industries to make considerable achievements
in energy saving. The applications range from energy-consuming industries, such
as iron and steel, electric power, oil and petrochemical, ceramics, pulp and
paper, food, and textiles, to various combustion facilities, such as
incinerators and small- and medium sized boilers. Combustion monitoring and
control using the analyzer also contribute to a lowering of CO2, SOx, and NOx
emissions by allowing for more complete combustion, thus preventing global
warming and air pollution.
Yokogawa Separate type Zirconia Oxygen Analyzer ZR22G/ZR402G
Yokogawa Oxygen Analyzer ZR22G/ZR402G features
include:
1)The separate type converter ZR402G
incorporates a LCD touchscreen for ease of operation.
2)The built-in heater assembly of the probe
can be replaced on site, reducing maintenance costs (ZR22G only).
3)The probe uses a long-life,
high-reliability, field replacable Zirconia sensor.
4) Remote maintenance using digital
communications (HART) reduces maintenance costs.
