FAQs of Digital Portable Hardness Tester with Printer:

Q: How does the digital portable hardness tester ensure accurate measurements?

A: The tester uses a standard D-type impact device (other types optional) and offers user calibration, which ensures reliable readings. Its indication error is 0.8% at 800 HL, and accuracy is rated at 0.5%, fulfilling stringent industrial standards.

Q: What is the process for printing test results with the built-in thermal printer?

A: After completing a hardness measurement, the device can directly print results using its integrated thermal printer. The user can initiate this function from the control panel, producing statistical analysis or direct reports instantly for record-keeping or quality documentation.

Q: Where can this hardness tester be used effectively?

A: It is suitable for on-site and industrial settings, including workshops, production floors, and field assessments, where metal hardness (such as steel, alloys, or copper) needs quick verification. Its robust, portable design allows for use in diverse locations free from strong vibrations and electromagnetic interference.

Q: When should I recalibrate the hardness tester?

A: It is recommended to recalibrate after changing the probe or conducting tests on different materials to maintain high accuracy. User calibration is straightforward and can be done as often as quality assurance procedures require.

Q: What are the benefits of its large memory capacity and data output options?

A: The tester stores up to 1000 test records, enabling efficient batch and single specimen documentation. With direct print, PC upload, and data output through USB or RS232, managing and analyzing results is seamless, supporting streamlined workflows.

Q: How is the device powered, and how long can it operate continuously?

A: The unit is powered by a rechargeable 7.4V battery or AC adaptor (110-240V). It boasts up to 20 hours of continuous operation, making it ideal for extended use in the field or busy industrial environments.
