110V數字熔點儀 TE-333

數字熔點儀 Digital Melting Point Meter

型號333和334數字熔點儀配備了液晶顯示器更快，更易讀，該液晶讀數也消除視差。儀器測量各種物質的熔點。用于測試塑料，蠟，樹脂，油墨，樹膠，脂肪，焦油，低熔點合金，有機和無機化合物等的模型333和334在范圍為120°F至500°F或50℃至260 °?下在焊機床面工作。該LCD可以由用戶設置顯示華氏或攝氏。

該儀器是便攜式的，可以在任何工作臺或書桌上使用。該模型333在110伏交流電運行，而334在220伏交流電運行。液晶顯示器是由一個9伏電池供電。位于開/關開關旁邊的指示燈加熱警告用戶。不銹鋼壓板（在照片的前景長期方棒）加熱的精確設計的溫度梯度。壓盤大約需要20至30分鐘，完全達到溫度。任何壓板的四個邊可以被用作測試端。

其測試方法是簡單，快速執行，只有幾毫克的樣品材料是必需的。將少量該物質置于沿上壓板上表面上。樣品的熔化和固體顆粒之間的分界線將被迅速見到。熱電偶結點被放置在這個分界點上壓板和下讀出。為了獲得最準確的結果，將少量樣品直接對熱電偶尖端，并從右邊移動熱電偶沿壓板離開，直到試樣剛剛融化。溫度讀數在這一點上是最準確的。

Models 333 & 334 Digital Melting Point Meters feature an LCD display for faster and easier readability. The LCD readout also eliminates parallax. Instrument measures the melting point of various substances. Used for testing plastics, waxes, resins, inks, gums, fats, tars, low melting alloys, organic and inorganic compounds, etc. Models 333 & 334 operate over a range of 120°F to 500°F or 50°C to 260°C along the platen bar. The LCD can be set to display either Fahrenheit or Celsius by the user.

The instrument is portable and can be used on any workbench or desk. The model 333 operates on 110 volts AC, while the 334 runs on 220 volts AC. The LCD display is powered by a 9-volt battery. Pilot light located next to the on/off switch cautions the user that the heating element is on. Stainless steel platen (the long square bar in the foreground of the photo) heats up on a precisely designed temperature gradient. Platen takes approximately 20 to 30 minutes to fully come up to temperature. Any of the four sides of the platen can be used as the test side.

The test method is simple and fast to perform, and only a few milligrams of the sample material is required. A small amount of the substance is placed along on the upper surface of the platen. The demarcation line between the molten and solid particles of the sample will be quickly seen. The thermocouple junction is placed at this demarcation point on the platen and the temperature read. For the most accurate results, place a small amount of the sample directly on the thermocouple tip and move the thermocouple from right to left along the platen until the sample just melts. The temperature reading at this point is the most accurate
