Profile

[Company strength]
Our portable, smartphone-sized LED luminance meter features auto-ranging for measurement convenience, a measurement range of zero to 200,000 lx, and support for pulse-width modulation dimming. The relative spectral sensitivity characteristics in the visible spectrum are within 6% of the standard spectral luminous efficiency, which complies with the General AA Class requirements under JIS C 1609-1:2006. Our meters offer high performance in a light, compact form at an inexpensive price. They can be used in greenhouses to measure changes in luminance over time with software set up to take automatic readings. They can also be used to manage work environment compliance with JIS lighting requirements at schools, offices, and factories.


[Business description]
Our company is involved in R&D, manufacturing, and sales of various types of optical sensors and application devices. We offer leakage sensors, pressure sensors, weight sensors (load cells and weighing platforms), and high-precision portable luminance meters relying on optical sensors. Our products are used in medical treatment, biotech, semiconductors, and many other fields. We have an abundant lineup of leakage sensors for detecting and preventing water leaks, oil leaks, and liquid leaks. These sensors are packed with decades of experience, and have been certified to UL standards and designed to CE and EMC Directive reliability requirements. They reliably detect all kinds of liquids. They are also finished with waterproof coatings. Our purpose-built leakage-sensor amplifiers can directly drive buzzers, lamps, and other indicators.

[Representative's message]
We can offer extraordinary performance by limiting our spectrophotometer’s measurement range to visible light at an astonishingly low price. Our product features ±0.3% T transmittance accuracy, 4.0 nm bandwidth, ±2 nm wavelength accuracy, and a stray light ratio under 0.3% at 340 nm and 360 nm. It comes with an industry-standard Czerny-Turner monochromator for stable linearity with minimal stray light in a compact form. Our spectrophotometer fulfils many needs beyond just research labs. It can be used for factory waste management (densitometry measurements for hexavalent chromium, cadmium, and other materials) and measurements of whiskey hues or tea densities. It is the ideal choice to supply one spectrophotometer per student in clinical classrooms because of its low price.


[Company structure for market development/overseas expansion]
Our extensive lineup of weight sensors and weighing platforms is distinctive for satisfying almost every need: large-sized, high-precision, explosion-proof, USB connectivity, and so on. We also have an array of pressure sensors to satisfy diverse usage conditions. This lineup includes standalone and built-in-amplifier sensors optimized for water pressure and oil pressure measurements, and sensors with enhanced chemical liquid resistance that use all-Teflon wetted parts. We also offer sensors rated to 0.5 MPa using Super Pillar Fittings from Nippon Pillar Packing, and sensors featuring Kurabo final locks. We are promoting our business with these sensor technologies.
