The Klein Tools TI250 is a rechargeable standalone thermal imaging camera delivering over 19,200 pixels of resolution on a 2.4-inch TFT LCD display. The VOx microbolometer sensor covers a temperature range of -4° to 752°F with accuracy of ±2°/2% above 212°F and ±3°/3% below 212°F. Internal 32 GB storage holds thousands of images. Three color palettes (ironbow, rainbow, grayscale) and adjustable emissivity from 0.01 to 0.99 enable thorough diagnostics for electricians and HVAC technicians. The rechargeable lithium-ion battery eliminates the need for disposable batteries. Backed by a 1-year limited warranty.
What is the TI250's thermal resolution, and what can it reveal?
19,200 pixels (160x120) — at this resolution a single image resolves individual breakers in a panel, pipe runs behind a wall, and temperature gradients across motor housings. For identifying overloaded circuits, moisture intrusion, and HVAC duct leaks, 19,200 pixels is practical for field use.
Does the TI250 require a phone?
No — the TI250 is standalone with a 2.4-inch built-in display and rechargeable lithium-ion battery. It operates independently of phone battery level, pairing, and positioning — the primary advantage over the phone-attached TI223.
How accurate is the temperature measurement?
Plus or minus 2 degrees C or 2% (whichever is greater) above 212 degrees F, and plus or minus 3 degrees C or 3% below 212 degrees F. For quantitative readings, hold the camera steady at a consistent distance and account for emissivity variation between materials.
What temperature range can the TI250 measure?
-4 to 752 degrees F (-20 to 400 degrees C) — covering refrigerant line surface temperatures, HVAC duct temperatures, motor housings up to 400 degrees C, and building envelope energy audits in cold climates.
How does the TI250 differ from the TI290?
The TI290 delivers 76,800-pixel resolution (4x the TI250), adds WiFi data transfer, and extends the lower temperature range to -40 degrees F. The TI290 is appropriate for detailed inspection where fine resolution distinguishes adjacent components; the TI250 is appropriate for HVAC, electrical panel, and building surveys at lower cost.
