Brief introduction: TVOC is short for total volatile organic compounds, the composition of TVOC are extremely complex, which in addition to aldehydes, benzene, toluene, xylene, common and trichloroethylene, chloroform, naphthalene diisocyanate, etc, mainly comes from all kinds of coatings, adhesives, and various kinds of synthetic materials and so on. TVOC can exist in the form of evaporation at room temperature in air, its toxicity, irritation, carcinogenicity and special smell, can affect the skin and mucous membrane, produce acute damage to human body. Technical indicators: Detection of gas: Total volatile organic compounds (benzene, toluene, xylene, ketone, and aldehyde, amine, halogenated hydrocarbons, sulfur, generation and unsaturated hydrocarbon) Range: 0-10 PPM, 0 to 50 PPM, 0-100 parts per million, 0-1000 parts per million, 0-2000 parts per million (range of optional, not listed range can be customized) Resolution: 0.01 PPM, 0.1 PPM, 1 PPM resolution (optional) Detection principle: semiconductor principle, the principle of PID light ion (optional) Response time: 20 seconds or less Sensor life: more than two years Recovery: 20 s Repeatability: plus or minus 1% or less High capacity rechargeable lithium battery: 7.4 V battery Display: large screen LCD display Warning: dual alarm sound, light, can set the alarm value, alarm sound db, 80 db System self-check: battery, display, sensor, automatic diagnosis such as hardware failure alarm function Explosion-proof marks: EXibdIICT6 Protection grade: IP65 Working temperature: 70 ℃ to 30 ∽ Working humidity: 0-95% RH Size: 180 mm (length) x 110 mm (width) x 80 mm (thickness) Weight: 1 kg (charger)
