Thiết bị đo lường chất lượng không khí AQT530

Measurement performance – gases

Field performance – gases

¹⁾ All values are based on 1‑hour averages with factory calibration, no linear correction applied. Values are obtained from global field testing in major climate zones against reference instruments. The values represent typical values and may be different based on the location.
²⁾ At 10 V/m RF field test, the presence of electromagnetic interference in the range of 800 … 900 MHz may cause additional deviation for NO2 and O3.
³⁾ Typical R2 against a reference grade instrument derived from field tests globally.
⁴⁾ Mean absolute error against reference.
⁵⁾ Mean absolute difference of AQT530 reading from average reading of AQT530s.

Measurement performance – environmental parameters

Operating environment

¹⁾ Optimal performance at −10 … +30 °C (−14 … +86 °F).
²⁾ Optimal performance at 15 … 90 %RH. Operation in low humidity environments may weaken the gas measurement performance. Operation in high-humidity environments may weaken the particle measurement performance.
³⁾ Water uptake of particles may result in PM overestimation. In most cases this is indicated by the sensor.
⁴⁾ Specified for gas measurement device only

Powering

¹⁾ Humidity management active, particle measurement active, temperature < 0 °C (32 °F).
²⁾ Maximum consumption when humidity > 85 %RH, temperature < 0 °C (32 °F), default particle measurement cycle.
³⁾ Maximum consumption when humidity > 85 %RH.
⁴⁾ Maximum consumption when temperature < 0 °C (32 °F), default particle measurement cycle

Measurement performance – particles

¹⁾ Spherical equivalent size of DEHS particles. Lower detection limit of 0.6 μm defined as 50 % detection effciency for DEHS particles.
²⁾ Specified with ISO 12103‑1, A1 ultrafine test dust.
³⁾ Measured against a certified reference grade instrument at room temperature using Arizona dust equivalent (ISO 12103-1, A1 Ultrafine test dust). PM2.5 measured at 150 μg/m3 and PM10 at 1300 μg/m3.
Accuracy and precision are defined with 2 standard deviations.
⁴⁾ Unit-to-unit variation. Defined as difference of AQT530 reading from average reading of AQT530s.
