Measurement time is too long. A: The closed mode that may be selected is not appropriate. Try replacing a suitable shutdown mode.
The instrument cannot be heated after starting the test. Answer: The overheating of the drying unit may cause the thermal overload protection function to start. For safe operation, the instrument is equipped with double overheating protection: the drying unit has a thermal overload protection (bimetal sensor) that shuts off the heating unit. In this case, contact your supplier.
Poor measurement repeatability. A: Possible reasons are: 1: The sample is not uniform. For example, they have different ingredients. The more uneven the sample, the more samples are needed to obtain better reproducible results. 2: The selected drying time is too short. Extend the drying time or choose the appropriate off mode "weight loss per unit time". 3: The sample is not completely dry (eg due to surface crusts). Try mixing quartz sand for drying. 4: The selected temperature is too high or the sample is oxidized. Reduce the drying temperature. 5: The sample boils and continuously splashes to change the temperature. Please clean the protective glass. 6: When the protection glass is eroded, the heating amount cannot be fully utilized. Please clean the protection glass. 7: The temperature sensor is contaminated or damaged. Please clean the temperature sensor. 8: The console is not stable. Please use a stable console. 9: The external environment is unstable (vibration, etc.).
Our isostatic graphite and Molded Graphite were tested at the National Electrical Carbon Products Quality Supervision and Inspection Center. The main physical and chemical performance index as follows: the compressive strength--125 mpa, shore hardness -- 65 degrees, resistivity --12 mu Ω m. At the same time, the 10μm,8μm,6μm,4μm products have already began Large-scale production,.and unanimously acknowledged by customers. The 2μm,1μm graphite products are under trial. Our company high quality of isostatic pressing special graphite yield above 90%, far ahead of industry the yield of 70%, the first in the country.
Moisture meter common fault
The display remains blank after turning on. Answer: Possible causes are: no voltage; no power cord connected; fuse blown; instrument damaged.
EDM graphite, also known as graphite block for EDM, is a new type of material, which is now more and more widely used in the precision mold processing industry. At present, in mold processing plants in developed European countries, more than 90% of mold processing electrode materials are graphite. Copper, the once dominant electrode material, has almost lost its advantages compared with graphite electrodes.
