Take the tester to the job!

The TIME TH-170 (now TIME5100) series portable LEEB type metal hardness testers are world famous in industry and have been widely used for more than 20 years.  

The TH-170 testers are ideal for use in applications where bench mounted hardness testers cannot be used. They are a compact and portable tester with auto average calculation and internal memory; powered by a pair of AAA batteries and making it suitable for use on site, in the field or on the factory floor.

Using rebound technology, the hardness results are measured in the LEEB Scale (HL) which are then automatically converted and displayed directly in the selected test scale, such as: Rockwell C (HRC), Rockwell B (HRB), Brinell (HB/HBN) or Vickers (HV). 

Metals that can be tested include Steel (CWT, cast etc), Stainless Steel, Aluminium, Cast Iron, Copper and more.


TH-170 (TIME5100) - Standard unit for general metal testing (HLD)

The TH-170 uses a D-type impact device for general purpose testing of metal samples greater than 5mm thickness*.   

TH-172 (TIME5102) - Thin material (HLC)

Featuring a C-type impact device with a lighter impact force, the TH-172 can test surface hardened components, coatings and thin walled components from 1mm thickness, provided they are securely supported and "coupled".  * Samples that are not coupled can dissipate the rebound energy through vibration which can result in a false, low hardness reading.  

TH-174 (TIME5104) - Needle Point for hard to reach testing (HLDL)

To test in hard to reach locations we recommend the TH-174.  The DL-type needle point impact device is ideal for accessing deep, recessed and other narrow shaped surfaces such as teeth on gears, o-ring grooves or any notched or stepped components.


IMPORTANT - Each type of impact device has minimum test sample thickness and weight. You may require a rigid support and/or coupling to a thick, heavier, non-yielding surface to resist the impact of the device.

For the purpose of a LEEB hardness test, "Coupled" means securely clamped to a larger, solid support AND using coupling fluid or gel.
