How does the TK7 work and what is its operating system?
+
The TK7 is an industrial-grade handheld thermal imaging camera that captures infrared radiation and converts it into temperature readings displayed as a thermal image. It features a 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 TK7 features a high infrared resolution of 384×288 pixels with a 17μm pixel pitch, and an excellent thermal sensitivity (NETD) of <40mK (0.04°C) for detecting very subtle temperature differences. The lens provides a 49°×37° Field of View (FOV) with a spatial resolution (IFOV) of 2.23mrad and a minimum imaging distance of 0.4m. It is focus-free, meaning no manual focus adjustment is needed.
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 TK7 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 an intuitive touch span mode.
What are T-TWB®, IREdge, and Super Resolution?
+
These are advanced onboard image enhancement algorithms:
T-TWB® (High Temperature Difference Equalization): Optimizes images with a large dynamic range to show more thermal details, effectively shielding interference from high-temperature heat sources.
IREdge (Image Detail Enhancement): Enhances infrared image contours, sharpening the edges of measured objects for clearer detail in complex scenes.
Super Resolution (SR): Enhances image resolution and reduces noise, generating an image with twice the width and height of a standard thermal image, making smaller targets easier to distinguish and measure.
Does the device support color alarms and panoramic stitching?
+
Yes. It supports color alarms for temperatures above, below, or between specific thresholds, as well as dedicated humidity and insulation color alarms. 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.
What are the digital camera and video recording capabilities?
+
The TK7 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 and saves full temperature data for every frame for later analysis.
How long does the battery last and how do I charge the TK7?
+
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 TK7 is fully connected. It 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 TK7 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, real-time data streaming, 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 operating 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 TK7 comes with an upgraded 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 rugged and ergonomic, 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).
