David White Digital Eyepiece - DT8EP



Digital eyepiece for the DT8-05 Series Theodolites.
Can be used with the DT8-05P, DT8-05LP, and DT8-05LS.

the environmental monitoring in the cleanroom. Products including contact plates for surface sampling and settle plates for air sampling. Tryptic Soy Agar TSA supports the growth of wide variety of organisms. Different neutralizers such as Lecithin, Polysorbate 80, Lactamator, etc. were added to minimize antimicrobial activity.

LS-1100 Dry fluorescence Immunoassay Analyzer

Transformer oil acid tester is a fully automatic measuring instrument which adopts the extraction method to accurately detect the insulating oil acid value. This instrument can improve the working efficiency and test accuracy, and at the same time ensure the safety of the body by reducing the operator's contact with the samples and reagents.

The acid value is the trace value of potassium sulfate that neutralizes the petroleum acid in 1g of oil, which contains a certain amount of inorganic acid and inorganic acid. The acid value includes organic and inorganic acids contained in the oil. In most cases, oil does not contain mineral acids. Therefore, the oleic acid value actually represents the content of organic acids in the oil. The organic acid contained in the new oil is mainly cyclonic acid. In the oil and in the process of use, the acid value of the oil produced by oxidation is an indicator to measure the degree of refining of the new oil. Whether the oil is running is an important indicator of the continued use of oil quality equipment.

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.
