Product Introduction:
The HRC SF640 is a highly sensitive long-wave cooled two-well infrared imager with 320*256 pixels. Its performance is among the leading in China and advanced internationally. This product can accurately detect SF6 gas leaks, with a thermal sensitivity of less than 0.025℃, capable of detecting extremely small temperature differences in equipment. It is suitable for gas detection and temperature measurement. Detectable gases include: sulfur hexafluoride (SF6), methylsilane, acetyl, methyl ethyl ketone, acetic acid, methyl vinyl ketone allyl bromide, acrolein, allyl chloride, propylene, allyl fluoride, trichloroethylene, ammonia (NH3), uranyl bromide methyl bromide, vinyl chloride, chlorine dioxide, acrylonitrile, vinyl ether, ethylene, furan, etc.
Product Features:
◆ Employs a cooled infrared focal plane detector with high sensitivity (<0.025℃), providing clear imaging and accurate temperature measurement.
◆ Suitable for various on-site environments, requiring no specific background or auxiliary light source.
◆ High-resolution, color digital touchscreen LCD.
◆ Features a fast leak detection mode.
◆ Dual functions: leak detection and temperature measurement.
◆ Autofocus or electronic focus.
◆ Autofocus or electronic focus allows for video recording for more intuitive observation.
