IR400 NDIR Type Infrared Gas Analyzer
Brand: Yokogawa Electric CorporationThe IR400 infrared gas analyzer is capable of measuring the concentrations of NO, SO₂, CO₂, CO, CH₄ and O₂ components in sample gas.
NO, SO₂, CO₂, CO and CH₄ are measured by nondispersive infrared method (NDIR), while O₂ is measured by built-in paramagnetic sensor or external zirconia sensor.
A maximum of 5 components including O₂ (up to 4 components except for CO₂ measurement) are simultaneously measurable.
The mass flow type twin detector of high sensitivity and reliability adopted in the infrared ray method detection unit makes the measurement hardly affected by interfering components.
In addition, the IR400 includes a microprocessor and has a large-size liquid crystal display, providing easy operation, high accuracy and multiple functions.
Optimum as an analyzer unit of measurement system for combustion exhaust gas from refuse incinerator and boiler, or gas from different industrial furnaces.
Features- Measure 5 components including O2 simultaneously and continuously
- Hardly affected by interference from other gases
- Equipped with abundant functions
- Large, easy-to-see LCD unit
- 19 inch rack mount structure
