O2 analyzer / flowmeter

PGA Series
Pitot-tube – Flowmeter
- Measures flow velocity through the vertical surface of the pitot tube using S-type pitot tubes (Dynamic pressure)
- Installs on one sid

GGA-70-1
Zirconia – O₂
- Measures ionization reactions based on EMF changes between platinum (Pt) electrodes using Zirconia (ZrO₂) principle, converted into oxygen concentrations
- Employs a K-type thermocouple for excellent linearity between temperature and EMF
- Maintains measurement accuracy through periodic automatic self-check cycles
- Utilizes an IC with built-in cold junction compensation (CJC) functionality
- Minimizes noise and protects heater lifespan with zero-crossing functionality
- Explosion-proof model available (GGA-70-1 Ex.)
