TT220 Coating Thickness Gauge Specifications probe type: F measuring principle: magnetic induction measurement range: 0-1250um lower limit of resolution: 1μm (10um following is 0.1um) probe connection: Integration Indication error: point calibration (um ): ± [3% H + 1] two-point calibration (um): ± [(1% ~ 3%) H + 1] Measurement conditions: minimum radius of curvature (mm): Convex 1.5 | 9 concave base diameter of the smallest area (mm): ф7 minimum critical thickness (mm): 0.5 Temperature and humidity: 0 ~ 40 ℃ | 20% RH ~ 90% RH statistics: average, maximum (MAX), minimum (MIN), the number of tests (NO .), the standard deviation of operating modes: direct mode (DIRECT) and group mode (Appl) Measurement: continuous measurement mode (CONTINUE) and a single measurement mode (SINGLE) set upper and lower limits: No Memory capacity: 15 measurements Print / connect a computer: optional printer / can connect the computer shuts down: Auto Power: two 3.6V NiCad battery Dimensions: 150 × 55.5 × 23mm Weight: 150g existing spark detector mostly divided 4KV, 8KV detection equipment , 35KV are three different for measuring coating thickness. Most OUD3 type spark detector instrument itself is equipped with a rechargeable battery, convenient site, workshop. Many different types of probes, in order to apply different working environments and artifacts. Calculation table with the instrument detection equipment manufacturers can calculate the size of the specific location of the pressure, the voltage is too high, the coating breakdown voltage is too low to be detected defects such as pinholes, depending on your coating thickness. Use the instrument probe must not contact with the body, so as to avoid personal injury. Spark detector and use it for different purposes, it can be divided into geographical DC spark detector and two AC spark detector. DC spark detector is mainly suitable for field construction operations, fast and so easy to use and open space use. Primarily by lead-acid batteries or NiMH batteries. AC spark detector is mainly applied in factories, workshops and other closed-end, easy to use the power of local authorities. Mainly through the 220v power supply. According to different classification spark detector testing equipment production, the user can according to different user site, to select the appropriate instrument, but according to different detection range, configuration different detection probes such as low or high voltage probe.
