Laboratory Furnace LE

實驗室電爐 LE

Application：

LE Furnaces are suitable for laboratory testing in which exact temperature distribution， controlled increase and decrease of temperature， and controlled cooling are important， and where it is also desirable that the heating elements are not in the interior space with the samples. The LE is especially good for heating material for the heat treatment of metal， various tests of sintering， calcination， determination of the softening point or of material sintering， combusting samples， enamel firing etc. The LE standard design features heating spirals which are placed in silica glass tubes to protect the spirals from corrosion by aggressive materials which can be released during treatment of the charge. It also includes an HT60B controller and a slide valve for opening the air supply， an airing flue and a special rust-resistant coating.

Standard design of the LE furnace includes:

- manual door opening downwards with a safety limit switch

- HT60B programmable controller

- heating elements inside protective silica tubes

- slide valve for opening the air supply

- airing chimney flue

Optional accessories for additional charge include:

- upgrade to PID controller HT 40P

- exhaust ventilator with a draft damper (only with HT40P controller)

- enhancement of the controller with RS 232 or RS 485 PC communication line (Monitoring SW Ht Monit optional)

Benefits of the LE furnace line include:

- reduced jacket temperature

- dynamic temperature curve regulation at DIN 17052-1

- low power consumption

- very reasonable price

用途

-用于所有種類的實驗室測試，如醫(yī)療、口腔病學、衛(wèi)生學、陶瓷學、玻璃制作等。熔爐適用于一些技術(shù)測試，這些測試注重溫度的分布、溫度德控制和發(fā)熱元件和樣品同時在內(nèi)部空間時的冷卻控制。熔爐特別易于進行在金屬的加熱過程對物質(zhì)的加熱、不同的燒結(jié)實驗、煅燒、軟化點的確定、物質(zhì)的燒結(jié)、樣品的燃燒和彩烤等等
