Top 10 Best surface and hardness testing in 2026

Main highlights

• •DOUBLECHECK - Each strip has two identical color pads. If the color pad colors differ after testing, it indicates that the test may not be reliable it should be performed again.
• •SAMPLE CUP INCLUDED - Ensure the most accurate water hardness test results by using the included sample cup and filling the test water to the marked level.
• •200 STRIPS @ $0.04 EACH - The most strips available in the box with the lowest cost per test.
• •⁠INDIVIDUALLY WRAPPTED - For the longest shelf life possible the strips are packed in foils of 50. This prevents unused strips from going bad due to too much contact with air.
• •DUAL TOP & BOTTOM DESICCANTS – Strips stay fresh for longer with two desiccants, one in the cap and one in the bottom of the bottle, to prevent moisture buildup.

Main highlights

• •【Calibration】First press the "Enter" key and then press the "On/OFF" key to display the average value and the nomimal (measuring for 5 times). Use the "Up and Down" key to adjust the true value to match the standard of the hardness block value, and then press the "Enter" key to start the hardness measurement.
• •【Equiped with D sensor】The Leeb Hardness Tester is equiped with D 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.
• •【Scale】Converts to all common hardness scales(HV ,HB,HRC,HRB,HRA,HS)
• •【Preset value】Upper and lower limit of hardness can be preset; When the tested value exceeds the limits, alarm will send out automatically to make convenient for the requirements of batch measurements
• •【Backlight】Back light display has been used to make convenient for the use in poor light
• •【Data storage】Max 500 groups（impact times:32～1）of data can be stored at internal non volatile data storage
