2、 (WiFi) Digital Leeb Hardness Tester TIME5351- Features:

The appearance is newly designed, with a novel shape, ultra-thin body, easy to hold, and good craftsmanship.

3.5-inch large screen LCD display, 320 × 480 color * * dot matrix, beautiful fonts and graphics, rich and clear information.

Equipped with 3-level brightness adjustment for display screen backlight and direct button operation, suitable for testing environments with different brightness levels.

Full Chinese display, menu style operation, few buttons, simple and convenient operation.

All display interfaces have operation prompts for easy operation.

Built in lithium-ion rechargeable battery and charging control circuit, no memory effect, easy charging, long lifespan.

It has the function of automatically identifying common impact directions (except for G-type impact devices). Adopting a digital impact device, it can be equipped with all 7 types of probes, with automatic identification of probe types, and does not require recalibration when replacing.

This machine can store 200 sets of measurement data, including single measurement value, average value, measurement date, impact direction, frequency, material, hardness, and other information.

Equipped with a MicroSD card interface, standard configuration 8GB, * expandable up to 32GB MicroSD card (hereinafter referred to as SD card) is used to store measurement data, meeting users' massive storage needs. The data on the SD card can be directly read on the computer, making it convenient and fast.

The upper and lower limits of the hardness value can be pre-set, and an automatic alarm will be triggered if it exceeds the range, which is convenient for users to test in batches.

The main display interface has information content such as date, time, memory information, battery information, electronic column, out of tolerance prompt, impact device type, operation prompt, etc., which is convenient and practical.

Equipped with a USB interface, it can upload data to the upper computer, print measurement data with an external micro printer, and perform various functions such as charging.

By using a microprinter, any number of test results can be printed.

According to user requirements, upper computer software can be equipped, and local measurement data can be transmitted to the upper computer in Microsoft Word or Excel format, meeting higher requirements for quality assurance activities and management.

Equipped with software calibration function for indication.

With the "Steel" material, when testing the "Steel" specimen with a D/DC type impact device, the HB value can be directly read, eliminating the trouble of manually checking the table.

It can be switched to a foreign hardness conversion table as a reference for hardness conversion.

Using WiFi technology to achieve wireless transmission.

Cloud transmission, synchronizing data between computers and tablets.

You can access data anytime, anywhere.
