[Company strength]
We offer digital multimeters including highly accurate products and high-resolution types with a PC Link, a high accuracy and built-in memory type with a PC Link, MΩ testers and bolt testers. We also offer analog multitesters including FET electronic testers, shock-resistant meters, and products of an automobile measurement compatible type, and for safety design power measurement. We also offer I0R (i zero ar) leak clamp meters that can achieve three measurement functions with a single unit, and can perform security work including monthly checkups and investigation of insulating failure points with a single unit, and a handy-type LCR meter that can automatically select resistance, capacitance, and inductance, allowing measurement with respect to unknown parts.


[Business description]
We have been manufacturing testers and various kinds of measuring instruments for more than half a century. We offer products including digital multimeters, analog multitesters, clamp meters, insulation testers, thermometers, tachometers, earth resistance testers, laser power meters, optical power meters, measurement software, standard calibrators, electroscopes and phase indicators, LCR meters, and school teaching material kits.

Measuring instrument manufacturing


[Representative's message]
We conduct product improvement by reflecting the opinions of users. An example of such product improvement is the industry’s smallest 7-range digital insulation tester with significantly improved routing, display visibility, anti-error operation property, and others. This solves complaints that we have received about conventional insulation testers. The complaints include users having to untangle lead wires at the line and ground sides before measurement starts; users needing to use a pocket tester for resistance measurement of a breaker, separately from the insulation tester; the lead wire at the ground side inside the electric switchboard being short and difficult to reach; and users needing to move their eyes while holding the main body and the probe tip end with both their hands.


[Company structure for market development/overseas expansion]
We have distribution agents in more than 74 countries throughout the world. We believe that follow-up systems for quality are important, so we will promote market development on the basis of quality support. We also contribute to society and improve the name recognition of our products in Japan through cooperation with the job training program “Electric Leakage Diagnostic Technology Learned by Practical Training.” This is done through advanced polytech centers, sales of teaching materials assembly kits for junior high schools, industrial high schools, vocational schools, and technical colleges, and for training for in-house technical experts and service engineers.
