Product Description

<p>The SUPCO IAQ55 is a professional indoor air quality meter designed for precise carbon dioxide monitoring. Equipped with a Non-Dispersive Infrared (NDIR) sensor, it delivers accurate CO2 readings with an accuracy of ±75ppm. The device also measures temperature (±0.9° accuracy) and relative humidity (±3% from 10 to 90% RH), and calculates dew point. Its LCD with backlight ensures clear visibility, while the audible alert notifies you when CO2 levels exceed set thresholds. The meter comes with a power adapter for continuous operation.</p><p>Ideal for HVAC technicians, facility managers, and indoor environmental quality assessors, the IAQ55 helps maintain healthy ventilation in offices, schools, and commercial spaces. As a Singapore-based supplier, 3G Electric offers SGD quotes on request, handles GST for local buyers, and provides fast delivery across Singapore and Southeast Asia.</p>
