Description:
This portable CO2 & CH2O composite gas detector supports simultaneous real‑time measurement of carbon dioxide and formaldehyde gas. Excessive CO2 will cause dizziness, drowsiness and suffocation risk in enclosed areas. Formaldehyde(CH2O) is toxic irritant gas, long‑term exposure may lead to eye discomfort, respiratory injury and other health hazards. Equipped with high‑precision infrared CO2 sensor and high‑performance formaldehyde sensor, the instrument features fast response, stable reading and strong anti‑interference performance. LCD screen displays CO2 and CH2O data synchronously. Once any gas exceeds the preset alarm value, sound, light and vibration triple alarm will trigger to warn field operators. Lightweight handheld design is convenient for mobile on‑site inspection. Widely applied in newly‑decorated rooms, office buildings, laboratories, factory workshops, warehouses and confined‑space operation sites. It comprehensively evaluates air quality and effectively protects personnel physical 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;
Feature:
- Multi Gas Detection: Supports combustible gas, oxygen (O2), carbon dioxide (CO2), toxic gases and TVOC
