Description:
This portable CO2 & TVOC composite gas detector is designed for simultaneous real‑time detection of carbon dioxide and total volatile organic compounds. High CO2 concentration may cause dizziness, fatigue and suffocation risk. Excessive TVOC will trigger eye irritation, respiratory discomfort and other health problems. Equipped with high‑precision infrared CO2 sensor and advanced TVOC sensor, the device delivers stable measurement, quick response and strong anti‑interference capability. The LCD screen displays CO2 and TVOC readings at the same time. When either gas exceeds alarm threshold, sound, light and vibration triple alarm will be triggered to remind on‑site personnel of hidden dangers. Adopting lightweight handheld structure, it supports mobile field inspection. Widely used in indoor environment detection, factory workshops, confined spaces, breeding houses, warehouses, new decoration sites and industrial environmental monitoring occasions, helping users evaluate air quality comprehensively and guarantee personnel health and operation safety.
Function:
Inspect the gas concentration and alarm when it reaches preset alarm level.
High accuracy, good stability and good repeatability, long working life.
One-key operation to restore to factory default setting.
Adjustable two-stage audible-visual alarm threshold value.
Powered by rechargeable lithium battery with big capacity.
The built-in pump, stable flow rate, can be opened or closed;
