Technical characteristics

A set of light filters M-90 - set for use as a standard measure of the spectral transmittance coefficient to determine the error opacimeters.

 

Also this device can be called: M 90, M90.

Nominal values ​​SKNP filters at wavelengths of 560nm and 900nm - 0,5% ± 0,2%; 0,75% ± 0,2%; 0,85 ± 0,1%.
Limits of error in determining the absolute SKNP filters - no more than ± 0,005%.
Overall dimensions:
- Filter - 23h11, 7h4mm;
- Light window - no less than 6mm in diameter.
The weight of one color filter - no more than 20g.
Weight of the set in the bag - no more than 100g.

Set of filters M-90 is intended for use by state metrological control and supervision and repair organizations.
Set M-90 is used to verify opacimeters following types:
- Meters compact smoke exhaust KID-2;
- Smokemeters portable META-01;
- The channel measurement of opacity multicomponent gas analyzers Autotest;
- Meters smoke exhaust META-01 MT.

Structural features of M-90 and function sets

M-90 filters are made of optical grade glass HC-6, HC-7 and HC-8. Each of them is a parallel plate diameter of 9 mm, 1 mm thick. SKNP filter is determined by the value of the brand glass. Filters are glued into the case.
The principle of operation sets the M-90 is based on the attenuation of the light flux passing through the light-absorbing glass filter.
When using a set of filters installed in a special slot optical path smoke meter under test. Further actions are determined by the method of checking smoke meter.
M-90 filters are placed in the case, the device which protects them from sharp impacts and pollution.

Specifications M-90

The range and accuracy of measurements SKNP set of M-90 correspond to GOST 8.557-2007 "State verification schedule for SI spectral, integrated and reduced transmittance and absorbance in the wavelength range of 0.2 um - 50 um, diffuse and specular reflections in the wavelength range 0 , 2mkm - 20 pm. "
The service life of a set of filters is at least 10 years of age. Set of filters M-90 operated at an ambient temperature of 15 ° C to 25 ° C and a relative humidity of 80%.

In the price list contains not the whole range of products offered. Prices of goods, not included in the price list can learn to contact the manager. Also, our managers You can get detailed information about how cheap and profitable to buy instrumentation wholesale and retail. Telephone and e-mail for advice on the purchase , delivery or receipt are shown on the description of the goods. We have the most qualified staff, quality equipment and the best price.

 

LLC «Zapadpribor» - the official manufacturer's dealer test equipment. Our goal - selling high quality goods with best price offer and service to our customers. Our company can not only sell you the necessary instrument, but also offer additional services to its calibration, repair and installation. That you have a pleasant experience when shopping on our site, we have provided special gifts guaranteed to the most popular products.

 

We also provide such metrological procedure: calibration, tare, graduated, testing of measuring instruments.

 

The company takes an active part in such procedures as electronic bidding, tender, auction.

 

If there is no site in the descriptive information you need on the device you can always turn to us for help. Our qualified managers will update for you on the technical characteristics of the device from its technical documentation: user manual, certificate, form, operating instructions, diagram. If necessary, we will take a photo of your device, or a device stand. You can leave feedback on the unit purchased from us, the meter, the device, indicator, or product. Your review for your approval will be published on the site without contact information.

Description of the instruments taken from the technical documentation or technical literature. Most pictures of products made directly by our experts prior to shipment of goods. In the description of the device provided the main technical characteristics of the instrument: nominal measuring range, accuracy class, scale, supply voltage, size (size), weight. If the site you see the discrepancy device name (model) specifications, photo or documents attached - let us know - you will get a useful gift with-selling device.

While the need to clarify the overall weight and size or the size of the individual meter you can in our service center. If you need our engineers will help you choose the most complete analog or a suitable replacement for the device you are interested. All counterparts and replacement will be tested in one of our laboratories with the full compliance to your requirements.

In the technical documentation for each device or product, information is provided on the list and amount of precious metals content. The documentation gives the exact weight in grams of precious metals: Au gold, palladium Pd, platinum Pt, silver Ag, tantalum Ta and other platinum group metals (PGM) per unit item. These precious metals are found in nature in very limited quantities and therefore have such a high price.

On our website you can familiarize yourself with the technical characteristics of devices and obtain information on the content of precious metals in devices and radio components manufactured in the USSR. We draw your attention to the fact that often the actual content of precious metals differs by 10-25% from the reference one in a smaller direction! The price of precious metals will depend on their value and mass in grams.

All text and graphic information on the site is informative. The color, shade, material, geometric dimensions, weight, content, delivery set and other parameters of the goods presented on the site may vary depending on the batch of production and year of manufacture. Check with the sales department for more information.

If you can make repairs to the device yourself, our engineers can provide you with a complete set of necessary technical documentation: circuit diagram TO, ER, FD, PS. We also have an extensive database of technical and metrological documents: technical specifications (TS), the terms of reference (TOR), GOST (DSTU), the industry standard (OST) test procedure, the method of certification, verification scheme for more than 3,500 types of measuring equipment from the manufacturer this equipment. From the site you can download all the necessary software (the software driver) is required for the product purchased.

Our company carries out repairs and maintenance of measuring equipment in more than 75 different factories of the former Soviet Union and CIS.

We also have a library of legal documents that are related to our field of activity: the law, code, ordinance, decree, temporary position.
