The TIME TH5370 Portable Digital Hardness Tester is a smart Leeb hardness probe that connects to a mobile phone, currently limited to Android, over Bluetooth 4.2. The TIME TH5370 Portable Digital Hardness Tester transmits each hardness reading wirelessly and in real time to the "TIME Smart Test" app, supporting automatic recording, report generation and data sharing.
Hardness testing on site often means a measurement taken in one place has to be written down, carried back and re-entered before it can be used, which is slow and error prone. The TIME TH5370 Portable Digital Hardness Tester records data automatically and shares it as it is measured, which helps trace the quality control process and speeds up reporting, particularly when many parts are checked in a batch.
The TIME TH5370 Portable Digital Hardness Tester measures from 170 to 960 HLD and converts to HB, HRB, HRC, HRA, HV and HS scales, with a tolerance of plus or minus 6HLD and repeatability of 6HLD at HLD 760 plus or minus 30. The TIME TH5370 Portable Digital Hardness Tester identifies the impact direction automatically across 360 degrees, and upper and lower hardness limits can be set in advance to trigger an alarm during batch testing. A self-define material function lets users build their own conversion table by comparison test, and records can carry images, video and positioning for cloud storage, custom worksheets and report generation. The built-in lithium battery charges wirelessly, the probe is rated IP54 against dust and water, and runs for 8 hours from 0 to 40 degrees Celsius at just 85g.
Used in metal manufacturing, inspection and maintenance, the TIME TH5370 Portable Digital Hardness Tester is supplied by BAMR, South Africa's authorised distributor.

When to use the TIME TH5370 Hardness Tester
Use the TH5370 when you want to test Leeb hardness and record results straight to a phone in the field. It is a smart probe that pairs over Bluetooth with an Android device and the TIME Smart Test app, with an IP54 rating for dust and water and a 170 to 960 HLD range across HL, HB, HRB, HRC, HRA, HV and HS scales.
- 1Records straight to the appHardness values transmit wirelessly to the phone in real time, so readings, images and positioning are captured together without manual logging.
- 2Rated for harsh sitesAn IP54 dust and water rating lets the probe work in the kind of dirty, wet conditions that would foul an open instrument.
- 3Auto impact-direction and limitsIt identifies impact direction automatically and alarms when readings fall outside preset limits, which speeds up batch testing and cuts setup errors.

Frequently asked questions
Does the TH5370 need a phone connection to operate, and does it work with iPhones?
The TH5370 is a smart probe that pairs with a mobile phone over Bluetooth 4.2 for automatic recording and real time sharing of readings. This connectivity is currently limited to Android, so iOS phones are not supported.
What hardness scales does the TH5370 report?
The TH5370 reports HL (Leeb), HB, HRB, HRC, HRA, HV and HS. Its measuring range is 170 to 960 HLD.
How accurate is the TH5370 across its measuring range?
Tolerance is ±6HLD and repeatability is 6HLD, both figures stated at HLD=760±30, across a full measuring range of 170 to 960 HLD.
Do I need to reposition the workpiece to test different orientations with the TH5370?
No. The TH5370 has a 360° measuring direction, so it can take readings at any angle without the workpiece needing to be repositioned.
How long does the TH5370 run before it needs recharging?
The TH5370 gives 8 hours of continuous working time on a single charge, powered by a 6V/500mA supply.
