可燃性濃度極限測定儀

FRTA I™（可燃性濃度極限測定儀）設計用於測定各種可燃氣體或揮發性液體的可燃性下限 (LFL) 和可燃性上限 (UFL)。FRTA I 採用高壓電點火和目視觀察火焰傳播。

應用

FRTA I 用於測量空氣中氣體和蒸汽在規定溫度和壓力下的可燃性下限和上限。易燃性限值是編制易燃化學品安全處理指南和進行火災危險評估所必需的。

優勢和特點

• 精確設定實驗條件（高壓、高壓和高溫）。
• 記錄並顯示點火後的壓力時間曲線，以便於評估結果。
• FRTA I 配備了安全玻璃窗和防爆膜，用於排出玻璃測試容器爆炸/爆破時產生的碎片和壓力波，確保操作安全。
• 遙控點火（高壓火花點火）。
• FRTA I 的最高工作溫度為 150 °C。
• 無需外部電腦即可自主操作。

合規
ASTM E 681-09

The FRTA I™ (Instrument for Concentration Limits of Flammability Determination) is designed to determine both the Lower Flammability Limit (LFL) and the Upper Flammability Limit (UFL) of various f lammable gases or volatile liquids. The FRTA I applies high voltage electrical ignition and visual observations of flame propagation. 

APPLICATIONS

The FRTA I is used to measure lower and upper flammability limits of gases and vapors in the air at defined temperatures and pressures. The flammability limits are necessary for preparation of guidelines for safe handling of flammable chemicals and their fire hazard assessment.

 ADVANTAGES & FEATURES

• Precise settings of experimental conditions (high voltage, pressure and temperature)
• Recording and display of pressure time curve after ignition for easy evaluation of results
• Safe operation of the FRTA I equipped by safety glass window and bursting membrane for the evacuation of fragments and pressure wave generated by explosion/implosion of glass testing vessel 
• Remotely controlled firing (high voltage spark ignition)
• The maximum operating temperature of the FRTA I is 150 °C
• Autonomous operation not needing an external computer
