Temtop H2 HCHO&TVOC Air Quality Monitor

TVOC Formaldehyde Meter Temtop H2 The air quality detector is an integrative hand-held instrument which can detect the concentration of formaldehyde and TVOC in the air. The detector can meet the requirement of testing formaldehyde and TVOC on various occasions and display the real-time data of them in time to guarantee your health in the environment.Product Specification Detection Objects: Formaldehyde, TVOC Weight of Main Machine: 220 g Overall Dimension: 6.6*2.6*1.3 Operating Environment: Temperature Range: 0-50 ℃, Humidity Range: 0-90% RH Atmospheric Pressure: 1 atm Packing List 1* H2 Air Quality Monitor 3*AA Alkaline batteries 1* User Manual Measurement Index and Range Formaldehyde Measurement Technical Index: Measurement Range: 0-2 mg/m³ Resolution: 0.001 mg/m³ TVOC Measurement Technical Index: Measurement Range: 0-2 mg/m³ Resolution: 0.001 mg/m³ Main Pollutants In Air Do you know what's in the air you're breathing? Indoor air can be 5x more polluted than outside, due to everyday factors like fine dust. Volatile organic compounds (VOCs) VOCs are emitted as gases from certain solids or liquids: furniture, appliances, toys, flames, scents, cooking, grooming and cleaning. Almost everything produces VOCs even humans. When contained indoors, VOC emissions may quickly rise to harmful levels. With Temtop H2, you're always conscious of VOC accumulation and inspired to keep your air fresh. Formaldehyde (HCHO) HCHO is a colorless, poisonous, highly water-soluble gas with an obnoxious odor. Used in the manufacture of disinfectants, preservatives, and hundreds of industrial and consumer products such as adhesives, carpeting, decorative paneling, foam insulation, drapery, fiber and particle boards, and permanent press fabrics. Health Effects Emesis Allergic skin reaction Coughing, bronchitis, chest pains and wheezing Irritation in the eyes, throat and nasal cavities Labored breathing and lesions in the lungs Abdominal pain, diarrhea and possible hemorrhage in the stomach or intestines Headaches, loss of coordination and nausea Visual disorders and memory impairment Note:Because the equipment has been sealed in the package for a long time, it's normal to see the value of formaldehyde is high when you turn on the detector for the first time. You can calibrate it manually according to the following steps:1. Press the OK key for 5 seconds at first and then the buzzer will give out a "beep" sound. When the backlight symbol on the display screen flickers, the detector will enter into the calibration mode. please do not press ‘OK’ key before the calibration is finished2. Meanwhile, please put the detector in a ventilated place for 10 minutes and the equipment will do calibration automatically. When the backlight symbol on the display screen stops flickering, the calibration is finished.3. If the detector has not been used for a long time, please calibrate it according to the above steps.4. Gases like alcohols, carbon monoxide, hydrogen sulfide and so on will cause interference to the test of the sensor. Therefore, please keep away from such materials as alcohol cosmetics contain alcohol perfume, etc. ) cigarettes (containing carbon monoxide), smoke(containing acrylic acid) and fruits (containing ethyl alcohol) before detection.5. It's better to close the windows and doors for 10 minutes at first before testing formaldehyde in bedrooms, sitting rooms and cloakrooms. The average value of various locations test data in a room is the average content of formaldehyde in the room6. The detector adopts air free-flow diffusion sampling method. While the detector transfers from one room to another one, it takes a certain time to respond and the user needs to wait for 10 minutes to read the data.7. The air quality detector adopts the battery to supply power. If there's no operation within 30 minutes, the detector will be turned off automatically to save the power.Maintenance Temperature and humidity are beyond the normal condition; otherwise, the stability and accuracy of the detector will be affected. Please do not disassemble the internal devices and crust of the detector. While cleaning the detector, please use a dry cloth to wipe the crust and avoid using a wet cloth. Please do not shock or shake the product strongly.   Q
