The D-R 290 uses the double-pass method according to the auto-collimation principle. The light beam traverses the measuring path twice. The attenuation of the light beam by the dust content in the measuring section is measured and evaluated.

Key Benefits

• Continuous and contact-less measurement
• Automatic zero and span check
• Automatic measurement and correction of contamination of optical surfaces
• Extremely powerful and stable super-wide band diode (SWBD) light source
• Extremely low-maintenance
• Fail-safe shutters with purge air monitoring as option
• Certified according to EN 15267-3
• Compliant with US EPA 40 CFR 60 PS1 and ASTM 6216

Advantages of the new generation

• Digital Modbus interface according to VDI 4201-3
• Convenient operation with remote access option
• All settings can be changed without opening the device
• Compatible with universal display and control unit D-ISC 100

Applications

Suitable for dust concentration measurement

• on incineration plants
• on power plants
• on cement plants
• in the metal industry
• on plants according to IED 2010/75/EC
• on converter plants and asphalt mixing plants
• on plants for the incineration of biomass

Suitable for measuring the opacity of flue gas

• on plants in accordance with U.S. EPA 40 CFR 60 PS1, special MCOC required
• on cruise and container ships.

Suitable for measurement of dust load in warehouses

All gauges are constructed from high quality materials and are designed to last in the rugged outdoor environment.

TES’s Standard DDG is a low cost, rugged and reliable dust deposition gauge for monitoring in accordance with AS 3580.10.1. The unit comes with: glass bottle, glass funnel, rubber stopper and bird ring.

Mounting options includes heavy duty tripods and picket stands to meet Australian standard positioning of 2 ± 0.2m for funnel heights. Grade A glass is used for both our funnels and collection bottles. We supply 5L collection bottles to allow for high rainfall to be collected and not invalidate samples.

Relevant standards specify exposure periods are to be 30 ± 2 days.

The TES DDG can be partnered with one of our real-time dust monitoring instruments to provide users with both compliance and real-time measurements.

Applications

• Road and construction sites
• Industrial applications
• Remediation works
• Agricultural areas
• Landfill in urban areas
• Mining operations.

The post TES Dust Deposition Gauge (DDG) appeared first on Thomson Environmental Systems.

All gauges are constructed from high quality materials and are designed to last in the rugged outdoor environment.

The TES DDDG is an omni-directional dust deposition gauge capable of measuring dust deposition in 4 directions. It is ideal for companies seeking monitoring in accordance with AS 3580.10.2:2013. The unit is capable of gravimetric measurements only with the sample later analysed in an approved laboratory. The TES DDDG may also be partnered with one of our real-time monitoring systems to provide users with real-time data.

How it works

Localised dust levels can be accurately measured using a combination of exposure periods with the mass of deposited matter. Data is collected to evaluate the effects of dust-causing activities for both compliance and internal use.
TES use NATA-certified laboratories to categorise the type of particulate (combustible to non-combustible matter), however collected samples can be further analyzed upon request.

Applications

• Road and construction sites
• Industrial applications
• Remediation works
• Agricultural areas
• Landfill in urban areas
• Mining operations.
