Pro - Indoor Air Quality Monitor

Indoor Air Quality Monitor — CO₂, PM2.5, TVOC, CO, Temperature & Humidity

The Clear The Air Pro (CTA-PRO) monitors six environmental parameters simultaneously in real time. Built for commercial buildings, healthcare facilities, schools and construction sites across the UK and Europe — with no WiFi required, up to 2 years battery life, and full remote visibility via web and mobile app.

What It Monitors

CO₂ is monitored from 400–5,000ppm at ±40ppm accuracy — levels above 1,000ppm reduce cognitive performance, above 2,000ppm cause fatigue and headaches. PM2.5 fine particulate matter is measured from 0.3–10 microns. TVOC covers volatile organic compounds from building materials, cleaning products and furnishings across 0–65,000ppb. CO (carbon monoxide) is monitored from 0–1,000ppm at ±5ppm resolution — silent and potentially fatal. Temperature is measured from -40°C to +125°C at ±0.3°C accuracy, and humidity from 0–100% RH.

Built for Compliance

Every reading is automatically logged with timestamp and location, giving you the audit trail required for HSE, CQC, DfE and EU regulatory inspections. No spreadsheets, no manual records.

Who Uses It

Hospitals, GP surgeries and care homes rely on it for CQC compliance. Schools and multi-academy trusts use it to meet DfE ventilation guidance. Facilities managers monitor office air quality across multiple sites from a single dashboard. Construction sites use it to meet COSHH dust monitoring requirements.
