Accuracy through Multi-level Calibration
Factory Calibration
Lab Calibration
Spot Calibration
Through spot calibration, the equipment is calibrated over the cloud, reducing onsite manpower and maintenance cost. It is a periodic calibration performed quarterly or bi-annually depending on the air quality. Oizom uses a recently calibrated sensor-based system or a third-party system trusted by the client as a reference. The reference system should be a continuous monitoring system. Around 150 data points are collected at the same time-interval to re-calibrate a system on the spot.

Working Principles
Light Scattering
Electro Chemical
PID
Photoionization detection method is used to quantify TVOCs. Highly energized UV photons bombard the molecules and make them positively charged. These ionized molecules produce electricity which gives their volumetric concentration.
NDIR
Light Scattering
The sensor emits a laser beam to diffract through the air sample collected in the equipment. The intensity of the beam scattered from the particles provides particle size distribution and concentration.
Electro Chemical
The gaseous emission is treated electrochemically by applying an external potential. Each gaseous molecule like CO2, H2S, CH4 etc. is identified depending on their oxidation or reduction potential.
PID
Photoionization detection method is used to quantify TVOCs. Highly energized UV photons bombard the molecules and make them positively charged. These ionized molecules produce electricity which gives their volumetric concentration.
NDIR
The gases emitted undergo Nondispersive Infrared Radiation where the sample air is subjected to infrared radiation. Different gaseous molecules absorb IR at different frequencies. The amount of IR absorbed gives the volumetric concentration.

Software Capability
Cloud Software
Data acquired onsite is transmitted to the Oizom Terminal for analysis through our cloud platform. The results are then reverted to the users in desirable formats.
On-premise
Data can also be stored in the local server as per the customer’s requirements. Data is locally transferred using FTP to Terminal and final output is provided to the user.
