Thermal Master P1 vs P2

For home inspection with a supported iPhone, or sharing between iOS and Android, choose the matching Thermal Master P1 connector package. Choose the original P2 for its higher native detector resolution on a supported Android device, provided regional availability is confirmed. US buyers have an extra gate: the current P2 product title says “Canada Only.” P1, original P2.

Quick choice: phone fit first, detector detail second

Best for supported iPhones and sharing: Thermal Master P1

P1 earns this pick through iOS and Android support, rather than a resolution advantage. Its product page separates 160 × 120 native IR from 320 × 240 X³IR output, specifies 25 Hz imaging and lists 0.32 W consumption. We would start here for broad home-inspection patterns when phone compatibility matters most.

The exact package covered here is For USB-C / Gray / Excludes, meaning the phone holder is excluded. The maker's embedded product data identifies it as SKU 1A00800022. Lightning and holder bundles are separate selections; changing the color alone does not answer either question.

The main limitation is the smaller native detector. There are also material documentation conflicts about the lens and included adapter, explained below. We would not buy P1 specifically for macro electronics work on the strength of its short promotional specification.

Check the P1 package at Thermal Master.

More native detail for Android: original Thermal Master P2

Original P2's 256 × 192 detector is the reason to choose it over P1 when your Android device is supported. Its 512 × 384 X³IR output is enhanced processing, and its 25 Hz specification matches P1. The P2 page lists 0.3 W consumption and an athermalized prime lens; the P-series manual describes a fixed lens.

This record covers Only Android (No iOS), SKU 1170100193. It is the original P2, not P2 Pro or P2 Max. Their separate manual columns must not supply this model's host compatibility or macro capability.

The recommendation is conditional on supply. The model-specific title's Canada-only restriction takes priority as a buying question over the site's generic US shipping banner. If the maker cannot confirm your destination, choose a supported alternative from our best thermal camera shortlist.

Check original P2 specifications and regional eligibility.

P1 vs original P2: compare the native detector

The bars compare horizontal detector pixels only. They do not rank temperature accuracy or prove close-up performance. FLIR's imaging guidance explains that detector size, lens and target distance together set the resolution limit.

Do not read sensitivity as accuracy. The maker defines NETD as sensitivity to small temperature differences. P2's feature copy also prints “+2.7°F(0.1C)Temp Accuracy,” conflicting with its ±1.5°C description and the manual. We do not treat that isolated 0.1°C figure as an accuracy promise. The manual says its temperature parameters were obtained in a laboratory; it does not establish that the headline error applies throughout every field situation.

Phone, app, connector and power checks

Sources: P1, P2, P-series manual and computer FAQ. Treat the printed Android versions as document claims, not guarantees for every current handset. The manual's generic Android minimum also differs from P1's short specification.

Use the maker's compatibility checker for the exact phone and tested OS, then the Download Center. It now directs P-series owners to Thermal Master. Its current US iOS listing requires iOS 13.0 / iPadOS 13.0 or later. Older Temp Master documentation still exists: the app name matters when following setup advice.

There is another conflict: the current iOS app description includes P2, while the original camera's selector and manual say Android-only. An app's family list does not settle original-P2 hardware compatibility. For a new iPhone purchase, choose the documented P1 route or obtain model-specific confirmation.

On Android, the manual calls for USB OTG enabled and the required app permissions. P1 advertises a connector extended by 2 mm, but says it fits most cases; check whether your case lets it seat fully. Both depend on a connected host for viewing; the maker explicitly describes P1 as drawing its 0.32 W from the phone. Plan around a charged host: P2's runtime example also names a particular phone and battery, rather than establishing a universal inspection duration. Host power guidance.

Focus limits: when to choose a different camera

Neither cited specification establishes a numeric minimum focus distance for P1 or original P2. Ask for the distance and smallest target you need to distinguish before ordering a camera for tiny components. Digital enlargement is not a verified macro working distance.

P1's short “Spec” section claims macro/manual focus, 4.3 mm focal length and <35 mK sensitivity. Its formal table instead lists 2.2 mm, 52° × 39° and <40 mK; the manual says fixed lens. We retain that conflict rather than assume a lens upgrade. The P2 comparison marks both P1 and original P2 as having no macro lens, and identifies P3 separately as adjustable macro. Conflicting P1 sections, comparison.

For board work, investigate a camera with documented close focus and a suitable mounting arrangement. The focused thermal cameras for electronics guide covers that purchase; keep a P3 or P2 Pro specification out of an original-P2 order.

What the exact packages include

For P1, For Lightning and Phone Holder Includes change the order. Do not count a pictured accessory as included in every USB-C package. Add any required holder or host-connection adapter to your comparison before choosing. For a gift, get the recipient's exact phone first; our gifts for electricians guide helps check for duplicate tools.

1. 1

   Match the model

   Keep P1 USB-C, P1 Lightning and original P2 separate; do not swap in Pro or Max specifications.

2. 2

   Match the kit

   Confirm the connector, cable, case, holder selection and any required adapter in the actual offer.

3. 3

   Match the destination

   Recheck regional eligibility, stock, seller and return terms at checkout on each shopping day.

This is a shopping checklist, not a verified promotion. An early-sale banner does not establish an Amazon offer or prove that the same package is available on either day.

How we choose

We compared official product pages, embedded variant identifiers, the linked P-series manual and current app requirements, checked November 2, 2026. Recommendations reflect documented host fit and native detector detail. Lens, app and availability conflicts remain explicit; we have no physical test results for these cameras. Read How we choose and How we measure.

For winter survey planning, use thermal cameras for home heat loss. FLIR recommends at least 10°C / 18°F indoor-to-outdoor contrast for insulation inspections and warns that structural features can resemble defects. Building guidance. Follow the camera's manual, stay away from live components, and leave panel work to a licensed electrician.

Verdict

P1 is our phone-flexibility pick; original P2 is the stronger native-detector choice for supported Android use when supply is confirmed. For a US order, resolve the Canada-only label first. For tiny electronics, resolve minimum focus first. Then buy the exact connector and accessory package, rather than choosing by enhanced image dimensions alone.
