Product Description:
Digital Leeb hardness tester is developed Leeb hardness measurement principle based on the internationally popular metal material hardness tester. It has high accuracy, small size, easy to operate, and a wide range of measurement, especially for large, heavy-duty malleable pieces, example: roll turbine shaft, and applied to the components already installed and can not be demolished, for example, site hardness testing of pressure vessels, turbine units and other equipment.
Leeb hardness tester is widely used in petrochemical, aerospace, electric power, gas, automotive, shipbuilding, railways, machinery manufacturing and other industries.
Product features
1.Based on the principle of measuring the Leeb hardness, it can be measured in a variety of metal materials.
2.Easily switch to the hardness of all formats (HL,HB,HRB,HRC,HRA,HV,HS), parallel conversion of the measured value of the hardness
3.Using the big screen 128 x 64 graphics dot matrix LCD display, information is rich, intuitive.
4.With bright backlight display, easy to use in the light gray environment.
5.A host can be equipped with 7 kinds of different impact device, automatic identification of impact device type. No need to re calibrate the replacement.
Main application
1.Installed mechanical or permanent assembly parts.
2.Heavy work piece.
3.Invalidation analysis of pressure vessel, steam turbine generator set and its equipment.
4.Test space is very narrow artifacts
5.Bearings and other parts.
6.Requires a formal original record of the test results.
7.Material distinction of metal materials.
8.Rapid test of multiple measurement sites in large scale workpiece.
Working condition
Working temperature: －10℃～＋55℃;
Storage temperature: －20℃～＋75℃;
The relative humidity is less than 90%;
There is no vibration, no strong magnetic field, no corrosive medium and serious dust in the surrounding environment.
Product Details:
Display All English display, menu operation, simple and convenient operation. OLED LCD screen, easy to use in any environment.
Measurement function One host can be equipped with 7 different impact devices, no need to recalibrate when replacing, and automatically identify the type of impact device.
Data storage It can store 48~350 groups (impact times 32~1) single measurement value, average value, measurement date, impact direction, number of times, material, hardness scale and other information.
Alarm output The upper and lower limits of the hardness value can be set in advance, and the alarm will be automatically alarmed when the range is exceeded, which is convenient for users to test in batches.
Calibration With indication software calibration function.
Battery The power supply adopts 2 AA (No. 5) ordinary alkaline batteries, which can work continuously for no less than 100 hours. It has power-saving functions such as automatic sleep and automatic shutdown.
Tip:
1. This Leeb hardness tester does not contain calibration blocks, you need to purchase calibration blocks locally. Thank you for your patronage!
2.This instrument is equipped with D-type sensor, which needs to measure the hardness of metal more than 5mm. D-type probe is a conventional probe, which is suitable for measuring most workpieces. Workpieces of special materials need to be equipped with other types of probes.
3.The three needle thread of the sensor has two colors of yellow and gray. Two colors of the line with random sensors, random delivery. Thank you for your support!
