Key Technical Specifications:

Model: Tekneka PC585 Video Particle Counter.

Measurement functions: Video particle counting, Formaldehyde (HCHO), TVOC, CO₂ (NDIR), Air temperature, Relative humidity.

Particle sizing / channels: (Video-based particle imaging — multi-size reporting) — ideal for PM0.3/0.5/1.0/2.5/5.0/10 µm equivalent bins (device reports particle counts and derived mass concentration).

Particle counting principle: Video imaging (camera-based) + image analysis for real-time particle counts and size distribution. 

Gas sensors: Electrochemical/metal oxide/NDIR hybrids depending on sensor: HCHO (formaldehyde), TVOC (total volatile organic compounds), CO₂ (NDIR). 

Measurement ranges (typical): HCHO: ppb–ppm range; TVOC: ppb–ppm; CO₂: 400–5000 ppm; Temp: –10 to 50°C; RH: 0–100% RH — see full datasheet for exact ranges and accuracy specs. 

Display & UI: Built-in color display with real-time charts; menu navigation for sampling, alarm thresholds and data export. 

Connectivity & data: USB / Wi-Fi / SD / cloud export (data logging and CSV export for trend analysis). 

Power & battery: Rechargeable battery + external power (portable for field surveys). 

Sampling flow: Built-in sampling pump with defined flow rate suitable for spot checks (see datasheet for L/min). 

Accuracy & calibration: Factory calibrated sensors; supports field recalibration and calibration certificates (recommended for compliance testing). 

Form factor & weight: Handheld / benchtop form factor optimized for portability. 

Typical applications: Indoor air quality (IAQ) surveys, HVAC commissioning, cleanroom verification, occupational health, building diagnostics.
