Approved Gas Analyzers

1. Japanese Measurement Law: Designated Manufacturing Business Operator

2. Japanese Measurement Law: Type Approval

In 1972, the Ministry of International Trade and Industry amended the Measurement Law to add gas concentration analyzers into its subjects as statutory measuring instruments.

Only the gas (NOx, SO2, CO, and O2) concentration analyzers which have passed the verification test can be used for transactions or certifications, for example, report to administrative agencies, certifications by laboratories, or indication of quality.

The following gas analyzers of Fuji Electric have obtained Type Approval.
