Our main business activities are evaluation data services related to
measurement/testing/analysis, consultation services for
evaluation technology, and design/manufacturing services for evaluation facilities.

In addition to standardized and specified evaluation data, we cope with method proposals,
conditions, and equipment most stable for the evaluation purpose,
design and manufacturing of original equipment and jigs for nonstandard evaluations.

We comprehensively handle 3 evaluation technologies, which are measurement,
testing, and analysis, so we are capable of offering evaluations
involving those three technologies and proposing more diversified evaluation methods.


We perform precision
measurement of parts dimensions
using equipment such as
Three Coordinate Measuring
Machine, Image Measuring Machine,
and optical 3D digitizers.

We conduct performance
evaluations and durability testing for
products/materials by
using vibration testers,
tension/compression testers,
electrical testers, etc.

We conduct morphological
observation and chemical analysis
using SEM, EPMA,
HPLC, GC, ICP, etc.


We cope with various needs related to product precision measurement based on our wide range of accumulated knowledge and equipment capacity which only a commissioned company could offer.

JTL is capable of optimal measurement for a variety of processes such as die-casting, resin molding, pressing, and cut parts. We respond to customer requirements in all areas, including precision measurement under temperature control and onsite measurement. We handle a broad range of needs ranging from individual measurements using manual procedures to multiple measurements using automatic programs, and installation of automatic measurement programs in customer’s lineside measurement equipment.
