Description
BDNDT provide all kinds of Hardness Tester in Bangladesh.
OLH300 Split color screen hardness tester is a portable measuring instrument that can measure the hardness of common metal materials quickly, without damage and with high accuracy. It can be used in both laboratory and engineering site. Through the setting of instrument measurement conditions, it can meet the needs of many kinds of measurement. This instrument is widely used in manufacturing, metal processing, chemical industry, commodity inspection and other detection fields. It is a necessary instrument for nondestructive hardness testing of materials.
The instrument meets the following standards:
——《JJG 747-1999 Leeb Hardness Tester 》
—— 《ASTM A956-06 Standard Test Method for Leeb Hardness Testing of Steel Products》
Product Features
- The probe is automatically recognized, plug and play (other manufacturers need to plug in the probe before turning on the machine).
- The high-performance ARM processor with Cortex-M4 core is used as the main control chip, and the processing speed is fast.
- Unique full-scale display all scales can be displayed on the main interface at a glance without looking up the table or switching.
- The Leeb hardness impact waveform display can judge the validity of the test and the working state of the impact device, such as whether the probe is worn or not, and whether there is dirt in the
- It can store up to 100 groups of hardness measurement data (impact times 32
~ 1). Each group of data includes single measurement value, average value, impact direction, times, material, hardness system and other information
- It has USB communication interface and is equipped with upper computer data processing software as
- It has the function of Bluetooth printing， and the Bluetooth printer can be optionally equipped
- According to the principle of Leeb hardness measurement, a variety of metal materials can be
- The power supply adopts 2 AA ordinary alkaline batteries, which can work continuously for no less than 50 hours; it has power-saving functions such as automatic sleep and automatic
- The instrument is compact, portable and highly reliable. It is suitable for harsh operating environment and is resistant to vibration, shock and electromagnetic
