HANNA - General Purpose pH/mV Meter HI 8424 Brand : Hanna Instruments Model : HI 8424 Product Description The HI8424 is an economical portable pH/ mV meter. This meter uses a BNC connector for the pH electrode input allowing for a wide selection of pH and ORP electrodes to be used. A separate temperature probe is supplied to provide temperature compensated pH measurement. The HI8424 is very basic in operation with automatic calibration to one or two points to any of the three programmed buffer values (pH 4.01, 7.01, and 10.01). The simplicity in operation and the economical price point has made the HI8424 one of the most popular meters available in the market. Product Features   Waterproof - Compact, heavy duty casing that is protected against any ingress of water that would damage the electronics. Automatic Calibration - calibration to one or two points to any of the three programmed buffer values (pH 4.01, 7.01, and 10.01). Automatic Temperature Compensation - Separate temperature probe is supplied to provide temperature compensated measurements. High Resolution/Accuracy mV Range - The HI8424 automatically switches resolution from 1 mV to 0.1 mV when ORP readings are between -699.9 to +699.9 mV. The accuracy within this range is ±0.2 mV. Automatic Shutoff - The automatic shutoff feature will turn the meter off after 20 minutes to conserve battery life. Low Battery Indicator - A low battery indicator will be displayed when the battery life is almost exhausted (5% remaining) alerting the user that a new battery will be needed in the near future.

LINSHANG - Coating Thickness Gauge Brand:  Linshang  Model: LS221 * (Fe & NFe Combination Probe) Features: * Accuracy: +/-(3%+2um) * Suitable for coating thickness which higher than 20micron. Product Introduction: The LS221 Coating Thickness Gauge is a specialist instrument for measuring the thickness of coatings on metal surfaces. The instrument combines the Hall effect and Eddy current principles to measure the thickness of non-ferromagnetic coatings on ferromagnetic metal substrates and the thickness of non-conductive coatings on non-magnetic metal substrates. The host and probe of LS221 is separate, which makes it easy for the user to view the data under complex testing conditions. It can be used in the laboratory and engineering field.  Hall Effect: can be used for the measurement of non-ferromagnetic coatings on ferromagnetic metal substrates.  Eddy current: can be used for the measurement of non-conductive coatings on non-magnetic metal substrates.  There are only four types of ferromagnetic metal elements at room temperature: iron, cobalt, nickel, and gadolinium.  Common non-ferromagnetic metals: copper, aluminum, zinc, chromium, etc.   Measuring principles Substrate Coating Examples Yes/No Hall Effect Ferromagnetic materials: Iron, cobalt, nickel, gadolinium Non-ferromagnetic metal 1.

RANKCONN - Electric Press Cut Machine ECM-10 Brand : Rankconn Instruments Model : ECM-10 Product Description ECM-10 electric press cut machine is a pure electric punching machine carefully developed by our factory. This machine is used by rubber and plastic factories and scientific research units to punch and cut standard rubber test pieces before tensile test. For similar materials, this machine can also be punched and cut. The machine is purely electric control (no hydraulic oil required), the precision screw drives the pressure plate beam up and down, and only the upper and lower button switches can be manipulated to complete the punching action. Compared with the first generation of products, it has the advantages of higher fuselage strength, more convenient operation, greater punching force and longer service life. Technical Specification 1. Stroke range: 70mmMax 2, punching force: greater than 20kN (2 tons). 3. Table size (effective): 220mm×200mm 4. Dimensions: 300mm×400mm×500mm 5. Power supply voltage: 220V 50Hz 6. Weight: 55kg Operation method   1. Put a knife mold pad on the base platform (thick cardboard or an abandoned thick book can also be used); 2. Place the specimen blank on the surface of the pad; 3. Place the cutter on the specimen on the table, make the cutting blade plane parallel to the base platform, and visually align the beam of the machine; 3. Press and hold the green button switch, the pressure plate beam moves downwards, the beam is in contact with the cutter, and the green button is activated until the standard specimen is completed. Press the red button on and off, move the table upwards to return to position (do not move the beam to the upper limit position), and then the cut specimen can be removed.   Precautions and maintenance   1. The cutting cutting blade plane should be parallel to the table plane, and the cutting-edge surface should not be in contact with the table plane when punching and cutting, so as not to damage the cutting knife blade. 2. After the punching cutting knife is used, it should be coated with anti-rust oil to prevent rust. 3. The pad plate under the specimen is not easy to select a strong plastic plate. 4. When the beam is returned, please do not move the beam to the upper limit position. 5. After use, apply dust cover to prevent oil and dust from infiltrating. read more
