1. Product descriptionHL140 portable hardness tester on the Richter scale, which can be directly measured rockwell (HRC, HRB), on the Richter scale (HL), brinell (HB), vickers (HV), shore hardness value (HS). In line with international standards and promulgated by the ministry of machinery industry "ZBN71010 hardness instrument technology conditions on the Richter scale - 1990", the state bureau of quality and technical supervision issued the "metal hardness testing methods of GB/T 17394-17394 on the Richter scale", the magnitude of the hardness meter standard JB/T9378-2001 standard, etc.
HL140 a host can be equipped with seven different impact device using automatic identification impact device types, you do not need to recalibrate when replacement. Ultra low power design, using high-performance lithium batteries achieve long work and the standby time, a more flexible design improved the flexibility of using.
2. Main featuresDisplay All Chinese display, menu operation, the operation is simple and convenient. White backlit display, convenient to use in dark environment.
Data communication With RS232 interface, a variety of communication methods to meet the needs of different user's personality.
Measurement functions It can be equipped with one host seven different impact device to use, does not need to recalibrate when replacement, automatic identification impact device type.48 ~ 350 groups of data storage can be stored (impact number 32 ~ 1) single measuring average value, and the date, number, material, hardness, impact direction system and other information.
Alarm output It can be preset on the hardness value, the lower limit, beyond the scope of automatic alarm, convenient user batch testing needs.
Help In all display can press "help" key to get prompt operation.
Calibration Software calibration value for function.
Battery Built-in high-performance lithium battery and charging control circuit, has long work and the standby time. Liquid crystal display battery symbol, real-time display the current remaining power.
Software According to the requirements of users, can be equipped with computer software, more powerful, meet the demand for higher quality assurance activities and management.
