Fgm optical fiber geometry analyzer is a new product after ofm optical fiber multiparameter testing system developed by rayscience .It can be used to replace the expensive imported machine. The equipment is based on grey calibrate technique of eia/tia fotp176.It is a high-precision intelligent instrument consisting of advanced optical system , ccd camera, computer and so on . Perfect software has been designed to calculate precisely all data collected from the optical fiber near field figure. The instrument can obtain the boundary of fiber cladding and diameter of core, at the same time it can provide all the geometry parameters .Test result is precise and reliable.
PERSONAL AIR SAMPLER INTRODUCTION
THERE IS A CHANCE THAT WORKERS AT MANY INDUSTRIAL AND CONSTRUCTION SITES WILL BE EXPOSED TO HAZARDOUS DUST, VAPOURS, AND GASES. SINCE INHALATION IS TYPICALLY THE MOST MAJOR ROUTE OF ENTRY INTO THE BODY, IT IS CRUCIAL TO PAY CLOSE ATTENTION TO THE AIR THEY ARE BREATHING.
IN GENERAL, WE USE A SAMPLE PUMP TO EXTRACT A KNOWN VOLUME OF AIR THROUGH AN APPROPRIATE SAMPLING MEDIA. FILTER PAPER OR OTHER SUITABLE SOLID MEDIUM WOULD BE USED FOR PARTICLES AND FUMES, AND A SORBENT TUBE, OR PERHAPS AN IMPINGER OR BUBBLER, WOULD BE USED FOR GASES AND VAPOURS. WITH THE SAMPLER SITUATED IN THE BREATHING ZONE, A TYPICAL SAMPLING TRAIN FOR PERSONAL MONITORING WOULD RESEMBLE THIS;
Gas sampling bags, like Tedlar bags, are used for collecting samples of gases. Moreover, background exposure can be measured using passive or diffuse sampling methods. They are sealed badges that are sampled, worn on the individual for the specified amount of time, sealed, and then sent off for analysis.
To enable hands-free sampling of inhalable gaseous pollutants and particulate matter in the air actually breathed by the person at work, Personal Air Sample is a battery-operated tiny air sampler that may be fastened on to a person.
Uses include: monitoring fugitive gas emissions in the workplace, workplace air quality, and workplace monitoring. They are also used in places of employment for businesses in the chemical, paint, cement, sugar, and other industries.
Features of the physical design include a holder for the sampling medium, a suction pump, a flow measurement device, a flow controller, and a battery for each personal air sampler.
For sampling of dust or particles, a suitable filter that has been placed in a filter holder serves as the sampling medium. An adsorption tube that is filled with pollutant-specific adsorbents like activated charcoal, tenax GC, etc. serves as the medium for sampling gases and vapours.
The filter or the adsorption tube must be the only one of the two media being utilised at once.
The suction needed to draw air through the sampling media is provided by a low power diaphragm type suction pump. A large capacity rechargeable Li-ion battery powers it. A tiny rotameter that has been carefully built can measure flow.A ball valve, a needle valve, or an electronic circuit can be used to control flow.
A battery-operated model with a rechargeable battery is one of its key features.
Used to monitor the air quality in workplaces or on shop floors. Small and Lightweight, weighing under 500 grammes
To assess TLV exposure, the filter holder or adsorbing tube can be held at the level of inhaling.
May be worn by the user
Model that is lightweight, convenient, and reasonably priced.
A corrosion inhibitor is a chemical compound or substance designed to mitigate or prevent corrosion, which is the deterioration of materials, particularly metals, due to chemical reactions with their environment. These inhibitors work by forming a protective layer on the metal's surface, blocking or slowing down the corrosion process. Corrosion inhibitors find extensive use in industries such as manufacturing, oil and gas, transportation, and infrastructure to prolong the lifespan of equipment, pipelines, and structures, ultimately saving costs and ensuring safety. They play a crucial role in safeguarding the integrity and functionality of metal components exposed to corrosive conditions, such as moisture, chemicals, or extreme temperatures.
Gel and Clot Activator Tube aims to obtain high quality serum specimen for biochemistry , immunology and serology tests in clinical inspection.
Inside the tube there is some gel present at the bottom, which is a pure substance and is very stable in physico-chemistry properties.
Otherwise, the gel can avoid high- temperature decomposition and small molecules precipitation, hence it greatly reduces the risk of testing equipment clogging.
