In general, proper calibration and maintenance of your gas analyzer equipment are required due to industry safety regulations. However, METTLER TOLEDO’s tunable diode laser oxygen analyzer uses software to “lock” its measurement to the wavelength where the target gas absorbs light. This means it does not drift and is effectively calibration free. That being said, demanding processes can have a harsh impact on instrument corrosion or contamination of the sensor’s optics. With METTLER TOLEDO’s preventative maintenance services, easy parts exchange can be done swiftly on your schedule to avoid instrument downtime and prolong replacement cycles.
