Portable multi-parameter air quality monitor designed to give fast, reliable readings wherever you need them Key benefits Protect health and safety: real-time measurement of CO2, TVOC, HCHO, temperature, and humidity helps you identify poor air quality and take corrective action before problems escalate. Make informed decisions: stable, accurate sensor data supports ventilation, remediation, and process-control choices in workplaces, living spaces, and production areas. Easy to use on the go: compact, lightweight design makes it simple to carry between rooms, sites, or greenhouses for quick spot checks. Core features Accurate detection: equipped with high-precision semiconductor and electrochemical sensors that provide stable, accurate detection of carbon-dioxide levels and other pollutants. Clear LCD readout: large backlit display shows real-time values for CO2, TVOC, HCHO, temperature, and humidity so you can read results at a glance in low light. Portable and lightweight: compact size and low weight make it convenient to carry, store, or move between monitoring points. Multi-parameter performance: combines gas and environmental sensing in one handheld unit to reduce the need for multiple instruments. Why this product stands out Focused sensor pairing: the combination of semiconductor and electrochemical sensing provides reliable detection across different contaminant types while maintaining stable CO2 measurement. Practical data at the point of need: instantaneous readouts let users verify ventilation effectiveness, spot-check newly finished spaces, or monitor controlled environments without delay. Versatile application range: designed to work in agricultural, commercial, and industrial indoor environments where air quality affects health, safety, or product quality. Typical use scenarios Greenhouse and crop rooms: monitor CO2, temperature, and humidity to ensure conditions support plant growth and to confirm ventilation adjustments are effective. Post-renovation or newly decorated interiors: check TVOC and HCHO levels in homes, offices, or retail spaces after painting or installation of new materials to decide when it is safe to occupy. Warehouses and light production areas: spot-check CO2 and VOC concentrations to protect workers, verify ventilation systems, and maintain compliant working conditions. Practical notes Designed for spot checks and portable monitoring; ideal for routine inspections, commissioning checks, and mobile troubleshooting. Readings are shown in real time on a large backlit LCD for immediate interpretation and action. This monitor provides straightforward, on-site air quality information—portable, accurate, and practical for a range of indoor environments where CO2, TVOC, HCHO, temperature, and humidity matter.
