FAQ

What are the analytical instruments in a chemical plant?

Chemical analysis instruments include analytical components: chromatographic analyzers, etc.Water analyzer for analyzing water contentInfrared analyzer for analyzing carbon dioxide content and so on

What instrument is used to detect formaldehyde more accurately?

The test principle based on formaldehyde self test box is recommended by the state as a colorimetric method of phenol reagent. Judging from the test results of formaldehyde, the formaldehyde self-test box is semi quantitative testing products, which can fully meet the needs of people to detect formaldehyde concentration in indoor air.

How do simple methods and instruments test drinking water quality?

The TDS value represents the total amount of dissolved substances contained in each liter of water (mg). According to experience and related information, generally less than 50, safe to drink.In order to strictly control the water quality, it should be checked according to the national drinking water standard.

What instruments are used for building subsidence observation?

The settlement observation, settlement difference and settlement velocity of building foundation shall be measured and the foundation inclination, local inclination, relative bending and component inclination shall be measured.

What are the methods of calibrating or calibrating a measuring instrument? How to operate?

In the 1 test, if the length of the level bubble deviates from the center, first with the foot long spiral level parallel adjustment, the amount of air bubbles to deviate from the center moved nearly half. The remaining half is adjusted with a correction needle, the levelling screw (on the right of the level) is adjusted to the center of the bubble.2 the instrument is rotated 180 degrees, check whether the bubble center. If the bubbles are not centered, repeat (1) until the bubbles are centered. ? ?3 the instrument rotate 90 degrees, with third foot screw adjustment in the bubble.

Audio analyzer for audio analyzer

The audio analysis instrument mentioned here refers to not only can measure the microphone, audio amplifier, speakers and other types of single audio equipment of various electro acoustic parameters, can the overall performance of combination test combination audio mixer, audio equipment analysis instrument. At present, the market has been the emergence of measurement can be used for all kinds of audio equipment, analytical instruments, such as distortion analyzer, spectrum analyzer, frequency counter, AC voltmeter, DC voltage meter, oscilloscope audio etc.. These rack type hardware instruments based on various functional circuits are easy to use and have high measurement accuracy, and have been widely used. Audio equipment manufacturers can analyze the performance of the instrument inspection equipment using audio, discovery of defects, and for the design of the equipment manufacturing is improved, consumers can also use audio analysis instrument to evaluate the equipment, choose the right product.

Notes on the use of oxygen analyzers

The change of oxygen content in sample gas will be affected by pipe material and surface roughness. Therefore, copper pipe or polished stainless steel pipe can be used in general connection line, instead of plastic pipe and rubber tube.

When total station instrument coordinates setting out, do not input angle instrument, high-energy lofting?

If you want to get elevation, without measuring the height of the instrument, you can pass the elevation of the back view point, if the elevation of the back view is known, and you need to take the back prism height.
