Gas Detectors Calibration
We Calibrate, Maintain and Service Multi-brand Gas Detectors of Fixed or Portable Type.
Moloobhoys are the authorized Sales and Service representatives / distributors of Gas Detector Manufacturer SCOTT Safety, GMI and OLDHAM in India. We provide on-site and workshop calibration support, service, inspection and maintenance of FIXED and PORTABLE Gas Detectors. We also have available ex-stock gas detectors and their spares, especially sensors and filters with us. Moloobhoy not only calibrate above brands but also calibrate other brand of the gas detectors.
A. S. Moloobhoy Offers below services for Gas Detectors:
• On-site and Workshop Calibration / Maintenance of Portable Gas Detector - Multi Brand
• On-site Calibration of Fixed Gas Detection System - Multi Brand
Calibrate
ATTENTION: Looking to Calibrate your Gas Detector Instrument? We perform Gas Detector Calibration for Portable Gas Detector and Fixed Gas Detector System. HOW?
By exposing the said instrument to a known, pre-determined concentration of a “test gas”, we conduct the calibration of the said instrument and verify if the gas is being appropriately detected by the said sensors.
Maintenance
Gas Detector maintenance is carried out as per pre-approved international norms. It is our job to ensure your instrument is able to collect appropriate and accurate readings. To achieve proper performance and accurate data/readings, we recommend Customers use our team of trained engineers, to service and maintenance their Gas Detectors on board their vessels at regular intervals. This will help SAVE LIVES from exposure to unsafe and explosive atmospheres on board vessels. Oxygen deficiencies and prolonged exposure to harmful vapors and toxic gases is serious and could be life threatening. It is our promise to keep you safe.
Services
Our trained and expert Engineers support in servicing of Multibrand Gas Detector. We support the service with spare sensors and filters of Original Equipment Manufacturer. Few brands we stock spares involves GMI, Riken Keiki.
Gas Detectors
Understanding the performance of most Gas Detectors
The performance of most Gas Detectors deteriorates with time. The rate of deterioration depends on the type of sensor that is used in the detector and on the overall operating conditions or the environment the tester is stored in or exposed to.
Taking for example a dusty or a corrosive or damp environment. Given that the specified “target market” is at “sea”, it is imperative to note that such factors will directly affect the frequency of inspection, overall required maintenance and the calibration.
For more detailed information please read: BS EN 500731 and the COGDEM Gas Detection and calibration guide. You are also welcome to email us at [email protected] for all your specific questions. We look forward to being of service to you.
What is the Corrective Action that is conducted?
Essentially it is the removal of these impediments. All gas detectors must be thoroughly inspected initially, before use, on an annual basis so as to ensure that they are capable of providing the expected performance and protection, that could ultimately save your life.
The LED display screen indicates “fault messages” when the exposed operational parameters are “abnormal”. By conducting a momentary magnetic “swipe” across any one, programming magnet, will allow the engineer to visually indicate and identify any scrolling “Fault Messages” as is applicable.
How do you Conduct an Inspection of a Gas Detector?
Visual inspection of all Safety Gas Detectors must be conducted quarterly to ensure that there is no external blockage of gas or vapour present in the primary path that then leads into the sensing chamber. Our engineer checks for debris, trash, mud or any other external equipment simultaneously to ensure optimum performance.
Understanding the Scope of Work or Service:
When “test gas” is “flowing” into the specific detector, inspection of the proper analog signal level output is made by reading the analog signal displayed on the control device.
Once the engineer sees a “stabilized response” signal within +/- 10% of applied gas level or +/- 2 ppm he is able to complete the testing satisfactorily. We always use this “test gas” reading/value that is approximately 50% of selected range. The engineer will check and see if response test is not within acceptable limits, then only will he insist that a Full Calibration procedure be performed and the Gas Response Proof Test re-performed.
Through this method, we keep the charges and costs for the Customer controlled and to the minimum.
