Review of FOTRIC 228 Pro Thermal Camera with 92-degree Lens for video recording of on-roof infrared moisture survey.

–by Greg Stockton  Stockton Infrared Thermographic Services, Inc.

I recently bought a FOTRIC 228 Pro Thermal Camera. This IR microbolometer imaging system has 640 × 480 (307,200 pixels) detector resolution. It uses FOTRIC LinkIR smartphone app to operate and FOTRIC AnalyzIR as the image post-processing software. It came with the standard lens…but I also opted to get the 92-degree Lens (L92-228). This is a super wide-angle lens (FOV 92°x76°).

Our company was engaged to perform an on-roof IR moisture survey of an office and laboratory facility. I wanted to document every square inch of the entire roof area for trending purposes. The roof is a 12-year-old TPO membrane, over 2 inches of polyisocyanurate insulation, over a metal deck.These types of roofs are a challenge as typically the window of uneven heat dissipation from the difference in specific heat capacity between wet and dry substrates is relatively short –owing to the lightweight, low mass cellular foam insulation boards. The total square footage was ~70,000 SF and roofs were on three different levels. The main roof had stairway access with two higher roof sections with fixed enclosed ladders for access.

I decided to create a radiometric video (large files) and by using AnalyzIR software, to convert the videos into smaller AVI files to deliver to the client, along with the report of findings. The FOTRIC 228 with 92-degree lens performed marvelously! Because the lens is so wide, the amount of time required to well-document every square foot of roof surface was just over an hour. I then went back to the areas where there were findings, changed the lens back to the standard and made my still IR images, along with flash visible light photographs.

熱像儀Fotric228 （帶92度鏡頭）在屋頂水分紅外檢測上的應(yīng)用介紹。

我最近買了一臺Fotric228 熱像儀。這臺設(shè)備的紅外分辨率是640×480（307,200像素）。它通過智能手機在FOTRIC LinkIR APP上進(jìn)行操作，F(xiàn)OTRIC AnalyzIR作為圖像后處理軟件。它配有標(biāo)準(zhǔn)鏡頭，但我也選配了92度鏡頭(L92-228)。這是一個超廣角鏡頭（視場角92°x76°）。

我們需要為客戶紅外檢測辦公室和實驗室的屋頂水分。我希望通過記錄整個屋頂每平方英寸的狀態(tài)來發(fā)現(xiàn)問題。屋頂表面的TPO防水層已有12年歷史，底部金屬板上覆蓋著2英寸多的聚異氰酸酯絕緣材料，中間層則是輕質(zhì)、低質(zhì)量泡沫隔熱板。由于隔熱板的濕基板、干基板之間比熱容的差異不明顯，導(dǎo)致屋頂有水分和沒水分區(qū)域散熱差異較小，這對檢測水分來說是一個挑戰(zhàn)。整個建筑面積約70000平方英尺，屋頂分三層。主屋頂有樓梯通道，兩個較高的屋頂部分有固定封閉的梯子供出入。

我決定拍攝一個紅外全輻射視頻（大文件）來記錄整個屋頂表面的每一平方英尺的狀態(tài)，并通過使用AnalyzIR軟件，將視頻轉(zhuǎn)換成較小的AVI文件交付給客戶，同時提供檢測報告。帶有92度鏡頭的Fotric228 ，拍攝起來非常棒！因為鏡頭視角相當(dāng)寬廣，拍攝屋頂表面每一平方英尺，所需的時間剛剛超過一個小時。然后，我回到有問題的地方，將鏡頭換成標(biāo)準(zhǔn)鏡頭，再拍攝紅外圖像和可見光圖進(jìn)行細(xì)致檢測。
