Background: Welcome to TZOA (pronounced ‘zoa’) - the world’s most advanced environment tracker. TZOA uses internal sensors to measure your air quality, temperature, humidity, atmospheric pressure, ambient light, and UV (sun) exposure, all in one wearable device.

Objective: Design and build a purified test chamber with zero air particulate to calibrate the TZOA devices against the DusTrak DRX 8533. An aerosolized cloud of ultrafine (0.3 - 20 μm) test dust was used to create the particle events.
