DT156 gage instrumentation _ Branch of the Instrument (certified) _ detection equipment provided by the Instrument Co., Ltd. Qingdao Branch. Instrument Co., Ltd. Qingdao Branch (www.qdjk17.com) is specialized in the "mapping equipment, analysis equipment, testing equipment, flow meters, optical instruments, temperature instruments," the enterprise, the company adhering to the "honesty, hard service" philosophy, to provide you with the highest quality products and services. Welcome to inquire! Contact: Li Yongjie. TT220 magnetic gauge | paint thickness gauge is an ultra-compact measuring instrument, it can quickly and without injury, precisely measure the thickness of non-magnetic coatings on magnetic metal substrates; widely used in manufacturing, metal processing industry, chemical industry, commodity inspection and testing in the field; the equipment is small, the probe and instrument integration, particularly applicable to the project site measurements. TT220 Coating Thickness Gauge meet the following standards: GB / T 4956─1985 magnetic method JJG 818-95 before "Reluctance thickness" JB / T8393-1996 magnetic and eddy current coating thickness gauge 1. Using the operator should carefully read the instrument manual, strictly regulate the use of detection equipment operation, to protect equipment, prevent fell, touch and temperature, not near a wet and corrosive gases. 2. To select the proper detection of ground testing equipment uses the principle, in order to ensure quality testing. (1) small size metal surface coating inspection, the object to be detected by an insulator support more than 20cm, then the ground wire connected to the well to detect metal objects. (2) for large volume or flat object detection, when the object has a good contact with the earth, just the ground wire to earth can be tested. 3. The detection process LX-A hardness tester, high voltage insulation testing personnel should wear gloves, no person shall contact probe and the measured object, to prevent electric shock! ! ! The measured surface coating should be kept dry, if stained with a conductive layer (dust) or water, difficult to determine the precise location of the leak. 5. When not in use, be sure to hit the power switch in the "off" position! ! ! 6. When the voltage indicator is lit, be sure to charge it in time! ! ! 7. The detector is equipped with high and low for the user to select the two probes, panel meter readings should be used, depending on the probe may be. If the high-pressure probe readings above the heads of the figures in Table prevail, whereas when using low pressure probe places following figures shall prevail.
