Portable Richmond Hardness Meter HLN160

The HLN160 portable Richter hardness meter can easily and quickly measure a variety of hardness values ​​(HL, HRC, HRB, HRA, HB, HV, HS) of multiple metal materials. This product is displayed in all Chinese, with a humanized interface, rich content, beautiful, clear and generous text and graphics, and is not affected by voltage fluctuations. To ensure measurement accuracy, it has dual functions of software calibration and hardware calibration. It can be equipped with seven impact devices, which are automatically recognized by the host, and there is no need to recalibrate during replacement. When leaving the factory, after multiple strict precision processing procedures, the accuracy is higher and the measured value is more stable. With a micro printer, it also has functions such as preset tolerance limit, over-limit alarm, display clock, etc., and is an intelligent and high-hardness testing instrument.

It is mostly used to measure heat treatment hardness and mold hardness. The DL impact device can be used to measure the hardness of narrow parts such as gears.

Features

It has power-on self-test function and factory parameter recovery function to ensure the normal operation of the system. It can shut down automatically in 5 minutes or work for a long time.

Two operating methods are adopted: direct method and menu method, which is flexible and convenient to operate.

It uses large screen dot matrix LCD, full Chinese display, humanized interface, rich content, beautiful and clear text and graphics, and is not affected by voltage fluctuations.

The main display interface can display date, time, storage information, battery information, overlimit prompts, impact device, direction, materials, operation prompts and other contents.

All interfaces have prompts, and various operations can be completed through prompts.

Large-capacity memory can store 250 sets of data (more than 6,500 single-time measurements). Each set of data includes: more than 26 single-time measurements, average values, test dates, impact directions, materials, hardness systems and other information. It can be stored for a long time for future browsing, editing, printing, and transmission.

It has a peak holding circuit and is highly adaptable to various impact devices.

The host can be equipped with 7 different impact devices to automatically determine whether the impact device is connected intact and automatically identify the impact device type.

It has dual functions of software calibration and hardware calibration, expands the calibration range and ensures test accuracy. The impact device that has been calibrated by software does not require recalibration during replacement.

It can be automatically converted into HRC, HRB, HRA, HB, HV, HS and δb according to the type, direction, and material of the impact device.

Automatically delete the overlimit data, and also set the upper and lower limits of the hardness value, and automatically determine the upper limit, qualified, and lower limits of the test data to realize automatic classification and inspection.

"Forged Steel" material has been added. When testing "forged steel" samples with D/DC type impact device, the HB value can be read directly, saving the trouble of manual table checking.

It has a warning and alarm function, and special warnings have aphorism prompts on the display interface.

The built-in intelligent voltage management system makes the power supply voltage stable and reliable, avoiding circuit damage and liquid crystal display abnormalities due to excessive high and low voltage.

There is a battery level indicator on the main display interface, a charging and charging prompt, and a charging indicator light, which is clear at a glance whether it is in a charging state.

The charging status instrument can work normally using an external power supply without affecting charging.

There is a backlit display, which is convenient for users to use in darker light areas.

The printer is integrated with the host, and uses a needle-type print head (optional for long-term storage), and prints in Chinese. You can print test results in any group or number of copies at will.

With RS232 interface, all measured data can be transferred to the microcomputer for easy microcomputer management.

There is a service information window that prompts the user to the address, phone number and contact person of the after-sales service center of this instrument to provide users with high-quality services.
