DJ-6-A电火花检漏仪
产品概述
DJ-6-A型电火花检漏仪是一款专为金属防腐涂层质量检测设计的精密仪器。该设备采用脉冲高压技术，可检测厚度范围0.03～1mm（支持定制）的搪玻璃、玻璃钢、环氧煤沥青和橡胶衬里等涂层。当涂层存在针孔、气泡或裂纹等缺陷时，仪器会通过明亮的电火花和声音报警提示异常位置。仪器采用12V直流供电，内置可充电电池，特别适合野外作业使用。15
技术特点
仪器配备600V～8000V可调高压输出，通过3位液晶屏直观显示实时电压值。具有全触摸面板操作界面和蓝色背光功能，在暗光环境下也能清晰读数。独特设计的自动关机功能可在闲置时节省电量，同时提供耳机和蜂鸣器双重报警模式，适应不同工作环境需求。主机体积仅220×130×88mm，功率消耗约6W，兼顾便携性和高效性。36
工作原理
DJ-6-A通过向导电基体表面的防腐层施加脉冲高压，当遇到涂层过薄、金属裸露或存在针孔时，会形成气隙击穿产生火花放电。此时仪器同步触发报警电路，通过声光信号指示缺陷位置。该检测方式能有效识别肉眼不可见的微小缺陷，保障防腐工程的质量控制。811
应用领域
本产品广泛应用于化工、石油、橡胶、搪瓷等行业，特别适合油气田管道、储罐、船舶、桥梁等设施的防腐层检测。可为自来水公司、燃气公司的金属管道维护提供可靠检测手段，也适用于大型工业设备涂层的定期质量评估。仪器配有多种可更换探刷，能适应不同形状工件的检测需求。1722
Product Introduction
The DJ-6-A spark tester is a professional instrument for detecting quality defects in anti-corrosion coatings on metal substrates. With adjustable output voltage ranging from 600V to 8000V, it can identify pinholes, bubbles and cracks in coatings like glass-lined steel, fiberglass and rubber linings with thicknesses of 0.03-1mm. The portable design with 12V rechargeable battery makes it ideal for field inspections. 125
Key Features
Featuring a 3-digit LCD display and touch panel, the device provides real-time voltage monitoring with blue backlight. Its dual alarm system includes both buzzer and headphone outputs for different working environments. The compact main unit (220×130×88mm) incorporates auto-shutdown function and consumes only 6W power. Various probe brushes allow flexible adaptation to different workpiece shapes. 626
Working Principle
By applying pulsed high voltage to conductive substrates, the instrument creates spark discharge at coating defects where metal is exposed. Simultaneous audio-visual alarms precisely locate flaws including micro-pinholes undetectable by naked eyes. This non-destructive testing method ensures reliable quality control for anti-corrosion projects. 828
Applications
Widely used in petrochemical, marine and industrial sectors for inspecting pipelines, storage tanks and steel structures. Suitable for routine maintenance checks by utility companies and construction quality assessments. The rugged design performs well in harsh environments with multiple probe options for complex geometries. 1722
