Dioxin

The dioxin measurement manual by the Ministry of the Environment defines methods for measuring dioxin in the environmental atmosphere. Here, we will introduce our products used for dioxin sampling in the general atmosphere with reference to the manual. In addition, we will also introduce equipment related to the collection and measurement of dioxin around the source.

Sampling Particle from opem face to PM2.5

For the measurement of airborne dust, the standards for suspended particulate matter (SPM) that cuts 10 μm 100% and fine particulate matter (PM2.5) that cuts 2.5 µm 50% are based on the “Environmental Standards for Air Pollution” established by the Ministry of the Environment. Here, we will introduce a sampler for collecting dust, a sizing device for sizing to each particle size, and a sampler that is the official method for collecting PM2.5.

Collection of suspended particulate matter

All-weather high volume air sampler standard type

It is an all-weather type sampler that collects harmful substances in the atmosphere at a high flow rate. A wide suction flow rate of 100 to 1200 L / min can be set. If the filter paper is attached in the open face, the suspended particulate matter will be sampled without particle separation. By setting various sizing separator on the filter paper, various sizing sampling is possible.

SPM  Suction flow 1000L/min

PM10  Suction flow 1000L/min

PM2.5 Suction flow 1000L/min

PM2.5 sampler (official method)

It is a sampler equipped with a WINS impactor that conforms to the standard measurement method set by the Ministry of the Environment. The constant flow device keeps the suction flow rate constant at 16.7 L / min and maintains the separation characteristics of PM2.5 of the impactor.

Portable High Volume Air Sampler

Although it is a non-all-weather type, it is portable and is used not only in indoor workplaces but also in air sampling.It has a wide suction flow range of 100 to 800 L / min. If the filter paper is attached in the open face , the suspended particulate matter will be sampled without particle separation. By setting various sizing devices on the filter paper, various sizing particle separation is possible.

Fence Line

There are increasing opportunities to monitor the dust discharged from factories and construction sites to see if it is discharged outside the site. Also, due to the growing interest in the environment these days, we are often asked to report to neighboring residents. Here, we will introduce products suitable for measuring dust concentration at fence line.

It is a microscope that supports polarization observation method and dispersion staining observation method.

Automatic measuring instrument (simple measuring instrument)

Fiber Monitor

Asbestos general environment measurement does not allow automatic fibrous material measuring instrument (fiber monitor), so it cannot be used as an official method, but we will introduce it as a simple measuring instrument because we can grasp the tendency in the field.

School Environment

School environmental management is carried out in accordance with school environmental hygiene standards, and the contents are divided into 6 items as follows ; “Environment such as classrooms”, “Water quality such as drinking water and facilities / equipment”, “Cleanliness of schools, rats, sanitary pests, etc. and Management of equipment in classrooms, ”  “Swimming pool”,  “Environmental hygiene in daily life”, and “Miscellaneous rules”. Here, we will introduce the measuring instruments used in the “environment in classroom”.
