Answer: ≤0.1mg/m3.(Refer to GB/T 18883-2002) 2.Why does the formaldehyde detector have so high power consumption? Answer: To guarantee the detection accuracy and sensitivity, the program needs to process a lot of complicated operations, which costs much usage of electricity. Turn off the power when detection ends to avoid waste of electricity. 3.How big is the product detection area? How many square meters specifically? Answer: i) 1~3 locations should be detected when the area is less than 50m2; 3~5 locations should be detected when the area is between 50m2~100m2; at least 5 locations should be detected when the area is larger than 100m2. All the detection locations should be distributed on the diagonal or in quincunx form. ii) detection locations should be kept away from air vent, and at least 0.5m far away from walls. iii) height of detection locations is comparable to breathe height of human, relatively between 0.5~1.5m Note: 1. The sensor of the detector may be affected by external disturbance just like all the other high precision apparatuses, so contact with ethanol, perfume or gas like H2S, CO, SO2 and smoke should be avoided. 2. When the detector is working, avoid straight wind flow from electric fans, warm air blower, air conditioner or air cleaner. 3.The average concentration of the targeted gas in a room can be obtained by detecting at several locations of the room and then averaging the data. 4. Don’t contaminate or block the detection window, otherwise sensitivity of the sensor may deviate. ## Features - Lightweight and portable, the formaldehyde detector is widely used for monitoring the indoor concentration of HCHO in home, office or car. - As well as the HCHO value, the three different colors display also indicates the formaldehyde concentration accurately. - Built in 360 degree detector ports in top of the product, it provides a precise air quality monitoring. If in a large room, please make it working in different locations and get the average detecting data. - Notice: The formaldehyde detector is also sensitive to alcohol, perfume smoke and other high concentration of HS, Co, so, etc. So, try to avoid them to get valid testing value. - ›See more product details ## Images ![Multi Tester Formaldehyde Detector(HCHO), Portable Air Quality Monitor for Car Home Office Precise AQI Meter with Light Alarm - Image 1](https://images-na.ssl-images-amazon.com/images/I/31wk%2BJR9l1L.jpg) ![Multi Tester Formaldehyde Detector(HCHO), Portable Air Quality Monitor for Car Home Office Precise AQI Meter with Light Alarm - Image 2](https://images-na.ssl-images-amazon.com/images/I/31fbzPl8kTL.jpg) ![Multi Tester Formaldehyde Detector(HCHO), Portable Air Quality Monitor for Car Home Office Precise AQI Meter with Light Alarm - Image 3](https://images-na.ssl-images-amazon.com/images/I/416PXLDNDdL.jpg) ![Multi Tester Formaldehyde Detector(HCHO), Portable Air Quality Monitor for Car Home Office Precise AQI Meter with Light Alarm - Image 4](https://images-na.ssl-images-amazon.com/images/I/41xbvmOMKZL.jpg) ![Multi Tester Formaldehyde Detector(HCHO), Portable Air Quality Monitor for Car Home Office Precise AQI Meter with Light Alarm - Image 5](https://images-na.ssl-images-amazon.com/images/I/51N2QkYRujL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Four Stars *by A***R on January 28, 2018* it is as advertised and pretty easy to read --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/50714232-multi-tester-formaldehyde-detector-hcho-portable-air-quality-monitor-car](https://www.desertcart.vu/products/50714232-multi-tester-formaldehyde-detector-hcho-portable-air-quality-monitor-car) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-06*
