Probe characteristics:
The NOVATECH 1231 zirconia probe (oxygen sensor) adopts the world's latest patented technology and applies the welding technology of zirconia sheets and steel jade tubes to ensure that the physical properties of zirconia sheets and steel jade tubes are consistent, achieving a consistent thermal expansion coefficient. Explosion will not occur under extremely cold and extremely hot environmental conditions. The probe has high measurement accuracy, no drift, fast reaction speed, strong thermal shock resistance, good corrosion resistance, and can be used normally in high water vapor and dust environments without specific calibration. The oxygen millivolt signal is consistent with the energy potential law curve, and the probe can withstand temperatures up to 1400 ℃, with a long service life of over 5 years. The cost of use and maintenance is low, and each component of the probe can be independently replaced.
Long service life and high measurement accuracy:
The NOVATECH 1231 zirconia (oxygen sensor) probe adopts patented and world leading zirconia and corundum ceramic welding sturdy composite technology, with strong resistance to thermal shock and a general service life of 3 to 5 years. The use of NOVATECH zirconia probes generally does not require calibration with standard gas (which can be corrected with ambient air). The probes have high oxygen measurement accuracy, fast reaction speed, no signal drift, and strong corrosion resistance during use.
Probe application range
The 1231 probe is suitable for measuring the temperature range of flue gas from 0 to 900 ℃. The probe comes with a heater and the outer protective tube material is 316L. Such as various boiler flues, etc.
Low price, no need for maintenance:
Due to the unique design of the NOVATECH oxygen sensing probe, it has a low investment cost and users do not need to repair it. The general service life is 3-5 years (depending on the specific usage environment). Generally, a new probe is considered after 5-6 years.
Rapid response to oxygen measurement:
NOVATECH zirconia device has an actual reaction time of less than 100 milliseconds, and the probe design has a reaction time of 1-4 seconds for oxygen, depending on the specific measurement method and filter conditions used.
Easy to install:
The probe is installed in a spiral manner. Users only need to drill holes and install a fixing nut or flange at the required installation location, screw the probe in, and then connect it to the wall mounted oxygen analyzer with a specific cable to work. When the probe length exceeds 1 meter, it is best to install a fixing device inside the probe. It is best to have an angle of 15-20 degrees during installation.
Unique corrosion resistance:
Suitable for various harsh environments, NOVATECH probes have unique corrosion resistance. For high sulfur areas, we have unique solutions. Please contact us for more details.
Convenient probe calibration:
The calibration method of NOVATECH zirconia probe is very simple, and can be calibrated with air. As the structure of the zirconia probe is completely based on the energy potential law curve, there is no need to use multiple standard gases to set the measurement range, which brings convenience and simplification to users.
