3520 Series -
KANOMAX USA, Inc.
The Kanomax Piezobalance Dust Monitor 3521/3522 is a unique respirable aerosol monitor, providing direct mass concentration of particulates using PIEZOBALANCE technology; ideal especially for oil mist monitoring. The Kanomax 3521 is equipped with 4 and 10µm impactors while the 3522 is equipped with a 2.5µm impactor. Unlike conventional dust meters, which count particles, a piezobalance dust meter like the 3521 or 3522 “weighs” mass concentration of particulates. As an air sample enters the system, it travels through the impactor, which captures and removes larger particulates away from the sample. Smaller particulates become electrically charged and deposited on the piezo-crystal. The total mass of the deposited particulates affects the piezo-crystal’s frequency. Since the change in frequency is proportional to the mass of the particulates, the actual weight of the particulates is obtained.

National Technical Systems
NTS operates some of the largest and most accurate sand and dust testing chambers available in the industry. We can accommodate parts in excess of 8 ft3 (0.25 m3) and comply with the requirements of various regulatory standards. While sand or dust circulate at up to 40 mph (65 kph) we can modify the test according to your special requirements, including running at temperatures of up to +200°F (+95°C). A calibrated “hopper” which assures that an adequate amount of contaminant is entering into circulation manages the input to the chambers. In addition to measured inputs, NTS employs an electronic beam, which determines that there is the right mixture of sand or dust and air in the test medium at any given time. This enables our technicians to adjust for loss in real time, and make corrections to ensure that the test article is exposed to the harmful particulate matter for the requisite amount of time.

3443 -
KANOMAX USA, Inc.
The Kanomax Digital Dust Monitor – Model 3443 measures aerosol concentrations corresponding to PM10. The intake isolates the aerosol sample so that the optics chamber is kept sterile for improved reliability and low maintenance. The unit measures 0.1 to 10µm particle size aerosol contaminants such as fumes, dust, smoke and mists. It is battery-operated, data-logging, light-scattering laser photometer that gives you real time aerosol mass readings. It is also suitable for clean office settings well as harsh industrial workplaces, construction and environmental sites, and outdoor applications.

Aero Nav Laboratories, Inc.
This test method is divided into two procedures. The small particle procedure, using fine dust is performed to ascertain the ability of equipment to resist the effects of fine particles which may penetrate into cracks, crevices, bearings, and joints. The blowing sand test, using coarse particles, is performed to determine whether equipment can be stored and operated under blowing sand conditions without experiencing degradation of its performance, effectiveness, reliability, and maintainability due to the abrasion or clogging effect of large, sharp-edged particles.

201LP -
Datatest Inc
The Redkoh Model 201LP is a three wire particulate monitor that measures particulate levels in air ducts on a real time basis. The Model 201LP is powered by an external 24V dc supply and its continuous 4-20 ma output can be connected directly to a PLC, recorder, or digital readout. Changes in the 4-20 ma output are directly related to changes in the concentration of particulate in the gas stream.

Keystone Compliance
Ingress protection testing tests the level of protection an enclosure provides against intrusions. Two such sets of ingress protection tests involve exposing the equipment under test (EUT), to dust. These tests are numbered IP5X and IP6X. The first digit, in the case of dust protected, would always be a 5, and in the case of dust tight, would always be a 6. The first digit, represented by the “X”, ranges from 0 to 9 and specifies the protection from liquid.

SICK Sensor Intelligence
Easy setup, accurate measurement, rapid resultsGravimetric dust measurement devices extract a partial gas flow from the duct under predefined conditions and use a filter to separate out the dust particles. The amount of dust is ascertained by weighing the filter. The differential pressure is measured to determine the extracted volume. These two values are then used to calculate the concentration of dust in the duct with a high level of accuracy. Gravimetric dust measurement is ideal for calibrating other dust measuring devices and for taking the kinds of comparative measurements that are required by the relevant authorities.

SICK Sensor Intelligence
Maintaining a clear sightline even when dust concentrations are highTransmittance dust measuring devices transmit light through the entire duct. With this type of measurement, light attenuation indicates the concentration of dust inside the duct. These measuring devices are specially designed for medium to high dust concentrations and large duct diameters. Consequently, they are equally suited to emission and process monitoring as they are to hall monitoring applications.

Dongguan Amade Instruments Technology Co., Ltd
Sand and dust test chamber is also referred as dust-proof chamber, which is able to simulate the sand storm by putting the test piece in the chamber to judge the damage of sand-and-dust weather to products. Equipment is mainly applicable to determination of sealing performance of product shells based on the IPX5 and IPX6 degrees. Testing machine features a flow of air carrying dust in a vertical circulation, resulting in cycle use of sand during the test. Sand and dust testing has great significance to master the specimen’s performance to defend the penetration of dust particles, to withstand the abrasion of sands.
