Description
The CEM DT-9897H thermal imager is a compact device with a resolution of 384x288 pixels. It is equipped with manual focusing and can zoom in up to 32 times, allowing users to get clear and detailed drawings. The device's display is a 3.5-inch LCD screen with touch control, and it also has excellent sensitivity of 0.05C and a measurement error of only ±2C.
The temperature range varies from -20°C to +1200°C, which makes this thermal imager versatile for a wide variety of applications. Information can be stored on 8 GB of memory, including a micro SD card and a 3.4 GB built-in EMMS memory. The device supports data transfer via USB.
Among the key advantages of the DT-9897H, it is worth noting the manual focus, which makes the image clearer in low light conditions or if several objects are in the frame at once. Enlarging the image to 32x the size facilitates the targeted study of small objects, which is especially important in science, construction, and electrical engineering.
The thermal imager offers 2 temperature ranges: -20 to +150°C for accurate measurements at low temperatures and 0 to +1200°C for higher values. It is also possible to select one of five display modes: infrared, visual, picture-in-picture mode, auto-mixing and distance measurement using the built-in rangefinder.
The variety of color palettes makes it easy to estimate the temperature distribution. For example, indicators above the norm are indicated in red, and below — in blue.
The CEM DT-9897H provides 5 ways to measure temperature: in the center, at a certain point, horizontally and vertically, as well as in areas with maximum or minimum temperature. Additionally, manual adjustment of the heat emission coefficient ensures precise adaptation of the device to various materials, including glass, wood and chrome-plated steel.
The settings for ambient temperature compensation and the effects of temperature fluctuations help to take into account factors that may affect measurement accuracy.

Specifications
Accuracy (or error) is the maximum allowable deviation of the measurement result from the actual temperature of the object. The smaller these numbers are, the more reliable the data you will receive.
- ±1°C / ±1% (High): Professional grade. It is necessary for energy audit, searching for microcracks in electronics and accurate scientific research. ±2°C / ±2% (Standard): The most common option. It is ideal for finding heat leaks in homes, checking the operation of underfloor heating and radiators.
- ±3°C and above (Basic): Budget models. They are suitable for household needs, when you just need to understand "hot or cold", without being tied to exact numbers.

- What it affects: When going beyond the specified limits (for example, in severe frost or in a hot workshop), the screen may start to "slow down", the battery will run out in a matter of minutes, and the measurement error will increase dramatically.
- For outdoor work in winter: Choose models with a lower threshold of -20°C or -30°C. Conventional appliances (from -10°C) can switch off at the most crucial moment.
- To inspect roofs in summer or industrial facilities: Pay attention to the upper limit (+50°C or +60°C), as the device body heats up in the sun or from the equipment.

Lower threshold:
- Usually -10...-20 °C: Important for finding heat leaks in winter, checking the quality of thermal insulation of walls and windows, and identifying "cold bridges" outside the building.
Upper threshold:
- Up to +120...+150 °C: Sufficient for checking heating systems, underfloor heating and finding blockages in radiators.
- Up to +300...+400 °C: Necessary for diagnostics of electrical panels, circuit breakers, loaded bearings and industrial equipment.

The minimum temperature difference that the thermal imager distinguishes. The lower the value, the better.
- less than 40 mK — high sensitivity, minor heat leaks and cold bridges are visible;
- 50-70 mK is a good level for most tasks;
- more than 100 mK — only for a rough diagnosis of overheating.
For building surveys where temperature differences are low, sensitivity is more important than high resolution.

Shows the size of the smallest detail that the thermal imager can distinguish from a distance. The lower the value, the better.
At IFOV 2 mrad, a detail of about 2 cm is visible from 10 m, and about 1 cm from 5 m. To inspect high ceilings, facades, power poles, and equipment from afar, choose a device with a low IFOV.
