Information About Measurement Laboratory Accreditation

At Shimizu, we actively research industrial waste, an environmental issue that cannot be ignored. In 1970, we established an Environment and Engineering Division as a research division for analysis and management of waste water. We have received accreditation as a measurement laboratory and work environment measurement agency from Osaka Prefecture, so you can use our products without concern. We are also involved in consulting with our clients regarding analysis of RoHS controlled substances, management of waste water, waste water equipment, etc.

Specified Measurement Laboratory Accreditation No. 10041

Main Measurements and Analyses

Air Atmospheric measurements, measures of heavy metals, hazardous mist, organic solvents, etc., in exhaust gas
Water quality Industrial wastewater, river water, sewage, etc. (living environment items, health items, monitored substances), and analysis of water quality of other general sources of water
Industrial waste Sludge, dust, slime, etc. (analysis related to disposal of waste in land fills and oceans)
Soil Analysis of soil and sediment
Working environment measurements Fine particles, organic solvents, specified chemical substances, metals
Analysis of RoHS controlled substances Heavy metals (cadmium, lead, mercury, hexavalent chromium), brominated flame retardants (PBB, PBDE)
