Research Instruments & Equipment

The MiniWRAS Model 1.370 is a compact, portable aerosol spectrometer designed for real-time measurement of airborne particle size distribution and concentration. It combines electrical mobility analysis and optical light scattering to provide high-resolution particle data across a wide size range. The instrument is ideal for ambient air quality monitoring, indoor air studies, and occupational exposure assessments.

The Fine Particulate (PM₂.₅) Sampler accurately measures fine particles (≤2.5 µm) in ambient air using a size-selective inlet system. It provides real-time mass concentration data for PM₂.₅ and PM₁₀ with a controlled flow and gravimetric sampling for precision. Widely used for regulatory monitoring, it supports air quality assessment and compliance with CPCB standards.

The Gaseous Pollutant Sampler is designed for precise collection of SOₓ and NOₓ in ambient air using a low-flow pump with rotameter-based control. It utilizes an impinger assembly with absorbing solutions for selective gas sampling and accurate volume measurement. With a compact, robust design, it ensures reliable performance in both field and laboratory applications.

The GRIMM 11-D Dust Monitor is a portable aerosol spectrometer for real-time measurement of particulate matter in ambient air. It uses laser light scattering to measure PM₁₀, PM₂.₅, and PM₁ along with particle size distribution. Equipped with an internal pump, precise flow control, and data logging, it ensures reliable monitoring in field and laboratory applications.

The Personal Air Sampler is a compact, wearable device used to monitor individual exposure to particulate matter in ambient and occupational environments. It uses a battery-powered pump with a size-selective cyclone or filter for accurate, constant low-flow sampling. Lightweight and portable, it enables gravimetric analysis for reliable personal exposure and workplace monitoring.

The Indoor Air Quality (IAQ) Meter is a multi-parameter device for real-time monitoring of indoor conditions. It measures CO₂, temperature, and relative humidity with accurate readings and data logging capability. Compact and portable, it is widely used for indoor air quality assessment in residential, commercial, and laboratory environments.

The Sound Level Meter accurately measures sound pressure levels in environmental and occupational settings. It uses a precision condenser microphone to provide real-time readings in decibels (dB) with A and C weighting options. Portable and robust, it includes a digital display and data logging for reliable noise monitoring and assessment.

The Noise Dosimeter is a wearable device used to measure an individual’s cumulative noise exposure over time. It continuously records sound levels using a precision microphone and calculates noise dose based on standard criteria. Compact and portable, it supports data logging for accurate occupational noise assessment and compliance monitoring.

The Burkard Spore Trap is used for continuous sampling of airborne biological particles like spores and pollen. It operates on a volumetric principle, collecting particles on an adhesive-coated moving microslide at a constant flow rate. Samples are analyzed under a microscope, making it ideal for routine ambient biological monitoring.

The EC/OC analyzer is an advanced instrument used for precise measurement of elemental carbon (EC) and organic carbon (OC) in particulate matter samples. It works on a thermal-optical analysis method, where carbon fractions are released at controlled temperatures under inert and oxidizing conditions. The system uses laser-based optical correction to accurately differentiate between pyrolyzed organic carbon and elemental carbon. With high sensitivity, accuracy, and automated operation, it is ideal for detailed aerosol characterization using quartz filter samples.
