Overview
The DGC DHT-310C Portable Leeb hardness tester is a Portable instrument for the measurement of hardness of materials with a C-type Impact unit. The hardness gauge features an integrated structure with an LCD display to visually display measurement readings and supports data printing with a Bluetooth printer.
Features
1. Integrated metal Leeb hardness tester, durable, small size, easy to carry
2. One-click conversion large interface, simple and convenient reading
3. Measurement parameters only need to be set through the three-key keyboard, easy to operate
4, can accurately and automatically identify any measurement direction in any situation
5. With the function of automatic measurement of average value, upper and lower limits can be set
6. With Data storage function, it can realize 1250 sets of Data storage
7, USB communication interface and cable for data transmission and battery charging
8. Built-in lithium battery, providing up to 16 hours of uninterrupted operation
9. Configurable Bluetooth printer to print measurement data
Principle
The hardness gauge adopts the principle of Richter hardness testing. Impact the surface of the specimen at a certain speed under the action of elastic force by the Impact body in the Impact device (Type C), and the ratio of the rebound velocity of the Impact body at 1 mm from the surface of the specimen to the Impact velocity is measured. The ratio is proportional to the Richter Hardness value (HL), which can be converted into a Miscellaneous Hardness scale.
Applications
Metal hardness of materials measurement
Steps
1. Loading: Press the loading sleeve down to the bottom, grab the Impact body, and then reset the loading sleeve.
2. Positioning: Press the hardness gauge Sensor vertically on the surface of the workpiece according to the selected measurement direction.
3. Release: Press the release button to release the Impact Body for measurement.
Notice
• When using batch storage, Miscellaneous batch storage should be selected immediately after storing a batch or choose to turn off storage, otherwise storage will continue, potentially affecting Miscellaneous data.
• If the factory reset function is used, the user's custom settings (such as address, Hardness standard, etc.) will be deleted, and the user is requested to record the settings by himself.
• If you do not use the hardness gauge for a long time, please charge the battery regularly to avoid damage to the battery and cause damage to the instrument.
• The Bluetooth printer uses a rechargeable battery, which can print about 90 meters of paper in one charge; this printer uses 57 * 40 standard thermal printing paper.
