Warranty & Support
- 1 Year warranty against any manufacturing defects.
- Client responsible for getting device to our facilities for all servicing. Service time 1 week.
- Warranty is void if device is opened, tampered with or electronics damaged due to mechanical shock.
- Sensor change and calibration is not included in warranty.
- PM sensor uses laser scattering principle: Light scattering can be induced when particles go through the detecting area. The scattered light is transformed into electrical signals and these signals will be amplified and processed. The number and diameter of particles can be obtained by analysis because the signal waveform has certain relations with the particles diameter.
- CO2 sensor is dual wavelength NDIR based (Nondispersive infrared sensor).
- TVOC is MOS Mems based sensor.
- Temperature sensor is CMOS, Humidity is Capacitive.
