Requesting regular maintenance and repairs for portable products

Gas detectors are important safety and disaster prevention devices.
They must be maintained and inspected at regular intervals to ensure performance and to improve disaster-prevention and safety reliability.
Maintenance consists of daily and monthly maintenance carried out by the workers using the gas detectors and periodic maintenance carried out by Riken Keiki service engineers.
Daily maintenance consists of visual inspections carried out by workers before work.
Monthly maintenance consists of inspections (alarm tests) of alarm circuits carried out by workers once a month. The regular maintenance carried out by Riken Keiki service engineers involves calibration with calibration gas; this requires dedicated equipment and calibration gas. Please contact your distributor or nearest Riken Keiki office for regular maintenance, including gas calibration.

Requesting regular maintenance and repairs of fixed products

Gas detectors must be maintained and inspected at regular intervals to ensure performance and to improve disaster-prevention and safety reliability during use. Using products without adequate maintenance will prevent accurate detection. Particularly in the case of special high-pressure gases, such maintenance and inspections are mandated by the Exemplified standards relating to the Regulation on Safety of General High Pressure Gas in Japan as follows: “Gas leak detection alarm systems for special high-pressure gas must be calibrated at least once every six months.”
Riken Keiki provides services related to regular maintenance, including gas calibration, adjustments, and servicing.
Preparing a calibration gas requires dedicated equipment, including gas cylinders of the specified concentration and gas sampling bags.
