Fluke iSee TC01A vs TC01B vs TC01C

For a Fluke thermal camera for iPhone, choose iSee TC01C for a supported USB-C iPhone or TC01B for a supported Lightning iPhone. Choose TC01A for supported Android or HarmonyOS phones with USB OTG enabled; the A and C models share a connector shape but have different documented platforms. Fluke's platform instructions establish this choice before image specifications enter the decision.

Ordering trap: Fluke's US TC01C entry contains a description that calls it “TC01B,” although its heading, included camera and part number identify TC01C. Match TC01C + 6047758 + Apple USB-C, and request clarification if the order description disagrees. Manufacturer links below let you check the model without relying on an unconfirmed marketplace identifier.

Best for supported USB-C iPhones: Fluke iSee TC01C

Buy TC01C when you want a direct connection to a supported USB-C Apple device. Its manual explicitly lists the iPhone 15 and 16 families and named USB-C iPads. For a newer or unlisted phone, obtain model-specific confirmation; an OS minimum and a matching socket do not settle the entire purchase.

TC01C's documented measurement ranges are −20 to 150°C and 100 to 550°C, with 25 Hz imaging. The camera contains no battery and draws power from the host. That makes checking phone charge part of preparing the inspection.

The principal uncertainty is the report workflow: the C manual lists report generation, while the family datasheet restricts its automatic-report claim to B. Confirm the installed app's output before choosing C for client reports. Its connector is the reason to select it over A, rather than an increase in documented IR resolution.

Best for supported Lightning iPhones: Fluke iSee TC01B

Buy TC01B for an existing supported Lightning device. The B manual lists the iPhone 14 family and numerous earlier phones and iPads. Check your exact model against that appendix rather than treating every Apple device as compatible.

Its documented ranges are also −20 to 150°C and 100 to 550°C, at 25 Hz. The manual includes picture editing and sharing, video capture, spot/line/area analysis and infrared report generation. Those are useful reasons to retain a supported Lightning setup if it already meets your reporting needs.

Upgrading the phone? The US product table says B needs an adapter for iPhone 15, but that entry does not identify an approved adapter model. Confirm the exact adapter with Fluke before ordering one. For a new camera purchase for a supported USB-C iPhone, our pick is C for its direct connection.

Check TC01B part 5589280 with Fluke

Best for supported Android phones: Fluke iSee TC01A

Buy TC01A for the documented Android/HarmonyOS route. Fluke specifies Android 6.0 or HarmonyOS 2.0 and later, with OTG enabled, in its family datasheet. Check current app availability on your actual phone before ordering; those published minimums are a starting point.

The datasheet gives A a −10 to 550°C overall target range, compared with the Apple models' −20 to 550°C envelope. More consequential for an order is the frame-rate ambiguity: it lists 9 Hz or 25 Hz A models, whereas the US webpage presents 25 Hz. The US model table supplies 5518338, without separately identifying both rates. We cannot establish distinct US part numbers for the two rates from these documents; get the supplied rate confirmed against the package.

The TC01A manual documents stills, video and temperature analysis. Do not transfer the Apple report promises to Android. If reports are your deliverable, see the workflow checks below before buying.

Phone fit: app support comes before adapters

Fluke's app-download page separates Android/HarmonyOS support from iOS and warns that app functions differ. The Apple manuals specify iOS 11.0 or later; the current developer's App Store compatibility entry also lists iOS 11.0 and iPadOS 11.0 minimums. Confirm both installation and accessory support for your device.

• Yes: TC01A: documented Android/HarmonyOS route with OTG enabled
• Yes: TC01B: documented Apple Lightning route
• Yes: TC01C: documented Apple USB-C route
• No: TC01A on an iPhone: outside Fluke's documented platform pairing
• Partly: TC01B on USB-C: Fluke says an adapter is required; confirm the exact accessory

Check case clearance before adding an extension. The instructions warn against force on the connector. Start by checking direct fit without the case. The cited model/package documents do not identify a case-extension accessory or an exact approved B-to-USB-C adapter, so this guide recommends neither as an established compatible product. A passive conversion should never be your evidence of app support.

Resolution, working distance and frame rate

According to the current datasheet, all three list 256 × 192 IR resolution, 50 mK NETD and a one-minute warm-up. The documented accuracy is ±2% of reading or ±2°C, whichever is greater, at 23 ±5°C ambient, as also stated in the current family instructions. Sensitivity is a separate specification; do not read the NETD number as absolute temperature accuracy.

• 256 × 192Specified IR resolution across the family
• 50 mKSpecified NETD; separate from accuracy
• 1 minuteSpecified warm-up time

The specified measurement distance is 0.25 to 5 m. For Apple-model measurements from −20 to 10°C, the manuals limit that to 0.25 to 3 m. For close circuit-board work, do not buy these specifications as a promise of accurate readings at a shorter distance. For winter work, distinguish the target-temperature range from the camera's 0 to 40°C operating range.

Do not choose A versus C by the headline resolution: their documented platforms decide the purchase first. Choose the A frame-rate package explicitly; the shared model name does not resolve its datasheet/webpage disagreement.

Saved images, analysis and report dependencies

The Apple manuals describe taking, editing and sharing infrared pictures, recording video, and analyzing spot, line and area temperatures. They also require measurement parameters such as emissivity, distance and ambient temperature to be set correctly. Save a representative job and inspect the result in the app before depending on that workflow for a report.

There is a real documentation conflict: the current family datasheet labels automatic inspection reports TC01B only, while the TC01C manual explicitly lists report generation. Treat C's report availability as needing confirmation in the current app; Android parity is also unconfirmed. If you require radiometric exports, desktop reanalysis or a particular report format, obtain a sample deliverable before ordering. A feature called “sharing” is insufficient evidence of those requirements.

Buying checklist: order a complete working setup

Fluke's US standard-package lists contain the camera, packaging box and user's manual; the camera manuals exclude the phone. All three manuals describe host power without a camera battery. Do not assume that a phone, adapter or extension is included.

1. 1

   Identify the host

   Write down the phone model, operating system and connector; verify the matching camera and app.

2. 2

   Identify the package

   Match the Fluke part number and frame-rate version; confirm any adapter separately.

3. 3

   Prove the deliverable

   Check fit, host charge, saved-image analysis and a sample report before committing to the workflow.

For a winter inspection, keep the 0 to 40°C camera operating limit separate from its below-freezing target range, and follow the family instructions: avoid damp or wet environments and account for emissivity, since reflective objects can read lower than their actual temperature. Leave panel work to a licensed electrician and follow the equipment manuals.

For the broader purchase, use our best thermal cameras guide. Our home heat-loss guide addresses that inspection job; the separate FLIR ONE compatibility guide covers another camera family if you are comparing alternatives.

How we choose

We compared Fluke's US model table, family datasheet, individual manuals and app documentation, checked November 3, 2026. Recommendations follow the documented host pairing and usable workflow; unresolved conflicts stay visible. This is document-based research, with no physical product evaluation. Our selection method explains the approach.

Verdict

Choose TC01C for a supported USB-C iPhone, TC01B for a supported Lightning iPhone, or TC01A for a supported Android/HarmonyOS phone with OTG. Confirm the exact phone and package, A's frame-rate version, any adapter and your report output before ordering. If those checks remain unresolved, use the linked alternatives guide before committing.
