Environmental Measurement Japan, Co., Ltd.

Environmental Measurement Japan, Co., Ltd. (日本環境計測株式会社) is a privately held Japanese company headquartered in Higashi-ku, Fukuoka City, Fukuoka Prefecture. It was established on 8 December 1999 with capital of 10 million yen and is led by Dr. Hiroyuki Katayama. The company's core business is the research and development of distinctive measuring instruments and sensors that reflect knowledge and experience of the diverse parameters relating to the environment and plants and their interactions; manufacturing, sales and export of the resulting products form its secondary activity. It also imports, exports and sells measuring instruments and related equipment generally, and provides maintenance, modification and repair services. The company's product range is organised around several application areas. Under SOIL it offers soil moisture meters, EC soil moisture kits, water potential instruments, soil oxygen sensors and tensiometers. Under PLANTS it covers chlorophyll fluorescence measurement, cultivation equipment, transpiration measurement and the Picas tree diagnosis system. Under WEATHER it supplies pyranometers, temperature and humidity meters, anemometers and radiation shields. Under GAS it offers carbon dioxide meters and fluorescence-quenching oxygen meters. Under DATA it provides readers and loggers. It also markets a Leaf Area Index (LAI) sensor (MIJ-15), a dendrometer, a soil oxygen sensor (MIJ-03), quantum (PAR) sensors and a range of temperature sensors including heavy-duty versions. In addition to its own products, Environmental Measurement Japan acts as a distributor for third-party instrument brands. Its website features a dedicated section for Vaisala products, including the HMP60, HMP110, HM70, HMP155 humidity and temperature probes, DTR500 radiation shields, GMP343 CO2 probes and GM70 handheld CO2 meters. The company serves customers in environmental monitoring, agriculture, forestry, meteorology and industrial measurement, and it exports its products internationally. Its stated support policy applies manufacturer warranties (generally one year) to both its own and third-party products, and it offers paid repair services, including for products purchased elsewhere or too old for other support channels.

Environmental Measurement Japan, Co., Ltd. was established on 8 December 1999 in Fukuoka City, Japan, with capital of 10 million yen. The company was founded under the leadership of Dr. Hiroyuki Katayama, who serves as its representative. From the outset, its stated mission has been to develop distinctive measuring instruments and sensors based on knowledge and experience of the diverse parameters relating to the environment and plants and their interactions. Manufacturing, sales and export of the resulting products constitute its secondary business activity. The company's business scope, as described on its website, covers four main areas: general research and development of measuring instruments; import, export and sale of measuring instruments and related equipment; maintenance, modification and repair of measuring instruments; and all incidental operations. This combination of in-house development and trading activity has shaped the company's evolution. Over the years it has built a portfolio of proprietary instruments organised around soil, plant, weather, gas and data-logging applications, including the MIJ-15 Leaf Area Index sensor, the MIJ-03 soil oxygen sensor, dendrometers, soil moisture meters, chlorophyll fluorescence measurement systems, transpiration measurement systems, the Picas tree diagnosis system, pyranometers, anemometers, radiation shields, carbon dioxide meters and fluorescence-quenching oxygen meters. Alongside its own products, Environmental Measurement Japan has acted as a distributor for established international instrument brands. Its website includes a dedicated section for Vaisala products, offering humidity and temperature probes such as the HMP60, HMP110, HM70 and HMP155, DTR500 radiation shields, GMP343 CO2 probes and GM70 handheld CO2 meters. This distribution activity complements its proprietary line and broadens its offering to customers in environmental monitoring, agriculture, forestry, meteorology and industrial measurement. The company operates from its headquarters at 2-52-42 Takamidai, Higashi-ku, Fukuoka City, Fukuoka 811-0215, Japan. It serves customers in Japan and exports its products internationally. Its support policy applies manufacturer warranties, generally valid for one year, to both its own and third-party products, and it provides paid repair services, including for products purchased elsewhere or too old for other support channels. The company remains privately held and active.
