10 Best Thermal Imagers on AliExpress

SMART SENSOR ST9450 weighs almost 400 grams, so it is more often ordered for the home than for hunting. The design of the thermal imager is successful: it fits comfortably in the hand, there is no feeling of heaviness even during prolonged use. The screen is backlit for use at night. It turns on with the push of a button. In the settings, there are five color palettes suitable for different purposes. This model has received a lot of positive feedback from customers due to its bright and clear picture with a high refresh rate. The thermal imager turned out to be simple and convenient to use, it has good sensitivity and a large TFT screen. There is only one significant drawback - the battery is quickly discharged.

Many devices from Aliexpress are quite expensive, but the price of the HT-02 is pleasantly pleasing. The manufacturer managed to save money due to the low resolution of the image and incomplete configuration. To work, you need to buy 4 AA batteries, rechargeable batteries will not work. The reviews note that the thermal imager works stably, quickly responds to movement and temperature changes. The camera is not bad, the build quality corresponds to the price - the plastic is not the most reliable, but there are no backlashes and factory defects. Buyers criticize the product for the lack of Russian-language instructions and batteries included. Considering that the HT-02 belongs to inexpensive devices, this minus does not seem so critical.

A thermal imager for a smartphone is a good portable solution. It takes up no more space than a regular flash drive, and in terms of functionality it is not inferior to full-sized devices. Such a device will be useful during hunting, because it can easily fit in a backpack and provide visibility at a great distance.The image is displayed on the screen of a smartphone, so the quality and resolution are directly dependent on the display. The viewing radius is significantly expanded compared to classic thermal imagers. On sale on Aliexpress there are versions of the model for iOS and Android. Buyers like SEEK THERMAL because it is relatively inexpensive, there are no problems with connection and control. The only downside is the delivery service.

A-BF RX-500 can be considered a versatile thermal imager. It has an impressive viewing radius and a resolution of 35200 pixels. Thanks to the clear picture, this model is suitable for any purpose: installing underfloor heating, checking the heating system, automotive work, etc. The device independently creates and monitors points of different temperatures. The kit includes a durable and convenient carrying case. An 18650 mAh battery acts as a power source, so you can not be afraid that the batteries will suddenly fail.In order not to waste the charge, the manufacturers have provided an auto-off after 5/20 minutes. The main disadvantage is that the measurement accuracy is lame.

A small device, resembling a slider phone in appearance, is equipped with a fairly large display. It is available in 2 colors, there are kits with an infrared thermometer or a laser rangefinder. This set will come in handy when hunting. The reviews praise the sensitivity of the device: with it, you can easily find the wiring, check the air in the batteries, etc. If you find fault, the Chinese charging can be attributed to the minuses. But the seller promises to add European plugs in the next batch of goods. XEAST HT-A1 is unlikely to suit those who came to Aliexpress for an inexpensive thermal imager. The price is quite high, so the model is chosen more often for industrial purposes than for domestic use.

A-BF RX-680 is an updated thermal imager RX-500, which eliminates all the shortcomings of the previous version (according to the manufacturer). It has a maximum screen refresh rate on AliExpress - 25 Hz. Other characteristics are at the level: high resolution, large viewing radius and temperature range. It's also nice that the device runs on battery power. Its capacity is 4500 mAh, a full charge is enough for 11 hours of operation. In the reviews, buyers praise the temperature resolution and the quality of the complete suitcase. The weakest point of the thermal imager was protection against water and dust - only IP54. It's better than nothing, but still not IP68. The device must be handled with care.

Hti HT-201 is another good smartphone thermal imager that connects via Type-C jack. The Thermal Viewer application is suitable for control, where you can watch videos and take photos. Despite the refresh rate of 9 Hz, the image is quite good. Delays and freezes are extremely rare, according to reviews. An updated version of the HT-301 model with a frequency of 25 Hz has recently been released. It costs twice as much, so it is not popular on Aliexpress. But users who have already bought a thermal imager were delighted with the image quality, high refresh rate and drop protection of the case. But the measurement accuracy leaves much to be desired in both versions of the device.

XEAST XE-26 is cheaper than other thermal imagers on Aliexpress, which could not but affect its quality. The image frequency here is minimal (9 Hz), as is the resolution. Of course, it is not recommended to use the device for professional purposes, but with its help it is quite possible to detect a leak or a warm floor. To save the results, you must insert a memory card up to 8 GB inside. The emissivity of the thermal imager is adjustable within 0.1–1 m, but manual focusing is not provided. Customers were satisfied with the sensitivity and picture quality on the display. The reviews only complain about inconvenient navigation and low measurement accuracy.

Hikvision H10 has a small picture resolution, but this is an honest figure. From the photos on AliExpress, you can see that the image is clear, without blurring the edges between colors. Thanks to a frequency of 25 Hz, it was possible to practically eliminate delays and braking in work.Such high quality is rarely found among inexpensive models. There is no English on the menu, only Chinese. But the seller is convinced that the controls are intuitive even without translation. There are three temperature measurement options, a switch between Celsius and Fahrenheit. The manufacturer also emphasizes that the device is suitable for repairing old thermal imagers, all parts are compatible with other brands.

The popular A-BF UTi260B has 7 picture styles. You can choose a color palette for a specific purpose - electrical inspection, repair work, hunting, etc. The files are stored on a memory card, the size of which should not exceed 16 GB. The body of the thermal imager is protected from dust and moisture according to the IP65 standard, it will withstand a fall from a height of 2 m. Among other things, the device is powered by a 5000 mAh rechargeable battery. It will last for at least 5 hours of operation.The reviews write that there are no delays in transferring the picture to the screen, the temperature is measured accurately. The only negative is that the real viewing radius does not exceed 1 m, although the description on Aliexpress indicates twice as much.
