Vasthi Instruments was formed with visionary thinking and innovative ideas resulting in innovative products and solutions. We enhance our product quality by the continuous process of research and development. We have WIDE range of models to suite various site conditions and processes.Vasthi InstrumentsBack Scattered Dust Monitor for Ideal monitoring opacity and smoke levels in the exhaust gas of industrial combustion or air filtration processes.Back Scattered Dust Monitortechnology means that the telescopic detector field of view is controlled to eliminate stray scattering from the far inside stack wall. The back scattered dust monitor is conveniently mounted on one side of the stack and usually requires no light absorber or beam dump on the opposite side of the stack. The optical parts include laser source, power control, photoelectric sensor and scattered light receiving.The 650nm laser beam sent by the laser at a tiny angle into the emission source, where it acts with the dust particles to produce scattered light.The back scattered light will be processed in the sensor into electrical signals.The circuit part will realize the photoelectric conversion, laser beam modulation, signal amplification, demodulation, light source power control, V/I conversion and HMI display.Calibrator is used to generate stable optical signals to zeroing and span calibration of the device.The Back Scattered Dust Monitor design has been implementing the thinking of no tool on-side installation , to minimize the complexity of field installation.

Vasthi InstrumentsVDPM 6000, Real Time Portable Beta Attenuation Mass Monitor, continuously measures the mass concentration of ambient particulate matter collected onto glass filter tape with time resolu-tion of one-minute. The VDPM-6000 employs an in-line sampling geometry in which the attenuation of beta rays across filter media is measured and particulate matter is sampled simultaneously. This allows ambient sampling to occur for virtually 60 minutes each hour. It also allows for beta ray measurements to be made for virtually the entire hour thereby improving sensitivity and time resolution. VDPM 6000 employs a unique in-situ sampling technique where the beta measurement is kept at a near fixed temperature above ambient conditions, thereby minimizing measurement error due to loss of semi-volatile particulate material or due to excessive moisture in the sample stream. Highly accurate measurements are made without having to employ expensive Nafion dryers thereby increasing reliability and decreasing operating costs. The integrated shelter does not employ air conditioning, nor does the sampling system employ flow splitters. This results in easier service, enhanced reliability and lower power consumption. VDPM 6000 comes integrated into its own lightweight equipment shelter with easily detachable pump box making it ideal for installation in areas where no permanent structure or walk-in shelter is available. Power consumption is modest as no air conditioning is required. No component weighs more than 40 lb. meaning that it is easily transportable by one person. The entire system may be set up and put into operation in less than ten minutes.
