How does the TK8 work and what is its operating system?
The TK8 is a compact handheld thermal imaging camera that captures infrared radiation and converts it into temperature readings displayed as a thermal image. It features a responsive 3.5-inch touchscreen and runs on a smooth, Android-based operating system for intuitive operation.
What are the core thermal specifications (Resolution, Sensitivity, FOV, and Focus)?
The TK8 features a high infrared resolution of 384×288 pixels with a 17μm pixel pitch, and excellent thermal sensitivity (NETD) of <40mK (0.04°C). The lens provides a 25°×19° Field of View (FOV) with a spatial resolution (IFOV) of 1.14mrad—allowing you to detect smaller targets at greater distances with a minimum imaging distance of 0.15m. It features manual focus, allowing you to rotate the focus ring on the lens for precise image clarity.
What is Super Resolution?
Super Resolution (SR) is an advanced onboard image enhancement algorithm that improves image resolution and reduces noise. It generates an image with twice the width and height of a standard thermal image, making smaller targets much easier to distinguish and measure.
What is the temperature measurement range and accuracy?
The temperature range spans from -20°C to 550°C, featuring intelligent range selection between two spans (-20~120°C and 0~550°C). The measurement accuracy is ±2°C or ±2%, whichever is greater (tested at 15~35°C ambient, target >0°C, calibrated at 1m).
What image modes and color palettes are available?
The TK8 offers four image modes:
Infrared Image: Full thermal view.
T-DEF® Blend Mode: Combines thermal and visible images with adjustable transparency (0% to 100%).
Picture-in-Picture (PIP): Overlays a thermal image on a visible light image (the PIP box is moveable and resizable).
Visible Light Image: Standard digital camera view. It supports 8 color palettes (Grey, Iron, Rainbow, GreyRed, Rain, GlowBow, Medical, Prism), inverted palettes, manual temperature span adjustment (minimum 2°C), and touch span mode.
What are T-TWB®, IREdge, and Color Alarms?
These are advanced imaging and diagnostic features:
T-TWB® (High Temperature Difference Equalization): Optimizes images with a large dynamic range to reveal more thermal details.
IREdge (Image Detail Enhancement): Enhances infrared image contours, sharpening the edges of measured objects for clearer detail in complex scenes.
Color Alarms: Allows you to highlight specific pixels that fall above a certain temperature, below a certain temperature, or within a specific temperature range.
What are the digital camera, video, and panoramic capabilities?
The TK8 is equipped with an 8MP industrial-grade digital camera. It supports standard MP4 video recording, as well as radiometric video recording (IRS/IRSX format) which captures full temperature data for post-analysis. Additionally, it supports panoramic stitching in infrared mode (3×1 and 1×3 modes), allowing you to combine multiple thermal images into a single panoramic shot directly on the device.
How long does the battery last and how do I charge the TK8?
The device uses a 3.6V, 5000mAh rechargeable lithium battery that provides ≥4 hours of continuous operation. The standard configuration includes 2 batteries for extended field use. You can charge the battery in the included dock (full charge in ~3.5 hours) or plug a USB Type-C adapter directly into the camera (full charge in ~2.5 hours).
What connectivity features (WiFi, Bluetooth, GPS) are included?
The TK8 features dual-band WiFi (2.4GHz & 5GHz), Bluetooth (for connecting headphones to playback voice annotations), and built-in GPS. The GPS location data can be saved directly to image files for geotagging your inspections.
Can I control the camera remotely and analyze data on a PC?
Yes. The TK8 supports multiple remote control methods: via PC (AnalyzIR software), mobile device (EasyIR Android app), or a web browser (IRExplorer) accessible from any device on the same network. It fully supports the AnalyzIR professional thermal imaging analysis software for in-depth analysis and report generation.
How do I upgrade the firmware and what languages are supported?
Firmware can be easily upgraded online via a WiFi connection, or offline using a TF card (via QR code verification). The system supports 10 languages: English, Spanish, French, Korean, Traditional Chinese, Japanese, Italian, German, Portuguese, and Thai.
What is included in the box, and what is the warranty?
The standard configuration includes the main unit, 2 rechargeable lithium batteries, a power adapter, a USB Type-C cable, a 32GB TF card & card reader, a calibration certificate, a warranty card, and a quick start guide. The TK8 comes with a 2-year warranty for the whole unit (the recommended calibration interval is 2 years).
What are the physical dimensions, IP rating, and storage capacity?
The camera is compact and rugged, weighing 0.8kg (including battery) and measuring 243mm × 95mm × 142mm. It carries an IP54 rating (protected against limited dust ingress and splashing water) and features a UNC 1/4-20 tripod connection. Storage is handled via TF card (a 32GB card is included, and it is expandable up to 128GB).
