A Continuous Ambient Air Quality Monitoring System (CAAQMS) monitors a city's air quality in real time. It continuously measures air pollutants throughout the year consistently. The pollutants measured include SO2, NO, NO2, NH3, CO, O3, CO3, VOC, PM10, and PM2.5. The CAAQMS is an advanced variant of the AAQMS air quality monitor system, utilizing high-quality innovations such as the Internet of Things for automated data collection, transmission, and analysis at a central server. Data is transferred in real-time, with adjustable intervals between 2 and 30 minutes. During intervals, the data is automatically analyzed using advanced AI for historical analysis and other applications.
PM 10 and PM 2.5
The Vasthi PM 10 and PM 2.5 Particulate Matter Monitors work The Principle of Particulate Matter 10 Analyzer uses the following technology: Ambient particulate matter, beta-ray detector for measuring the concentration of particulate matter whose aerodynamic equivalent diameter is smaller than 2.5/10 m on rolled filter tape The instrument uses low-radiation C14 as the radioactive source.
The emitted ray passes through the filter membrane with contaminants and will be received by the detector. The detector [1] is composed of a photomultiplier tube (or Geiger detector), a plastic scintillator, and a counter. The thickness can be analyzed quantificational according to β-ray energy that the detector received, and then the PM 10 and PM 2.5 concentrations in the air can be calculated received, and then the pm 2.5 and pm 10 concentrations in the air can be calculated.

Million Plus cities urban air quality monitoring station
Urban air quality monitoring station: With the help of a million-plus cities' air quality monitor, you can keep a check on the air pollution levels of various regions across the country and provide timely warnings to critical zones with high levels of pollution so that timely and effective measures can be taken to protect public health and safety.
The Urban Air Quality Monitoring Station device is equipped with multiple sensors for PM2.5, PM10, CO, NO2, SO2, O3, and humidity measurement (%). It also provides notifications based on the pollution level in your area and sends notifications to your phone when the pollutant level reaches a dangerous level.
The Air Quality Index (AQI) reading is indicated by color. The red color indicates a very high AQI level, which requires the public to avoid any outdoor activities; the orange color indicates a high AQI level, which requires the public to reduce outdoor activities; and the green color indicates a low AQI level, which is safe for human activities.
Accuracy: The device is certified by Indian National Measurement Institute (INMI) and has excellent performance accuracy. It accurately detects critical pollutants such as PM2.5 and PM10.
Multi Point Calibrator
Dynamic calibration of an instrument based on microprocessor technology, developed specifically for precision gas analyzers and multiple gas calibration equipments. Through the use of high-precision mass flow controllers and standard gases for gas parameters like zero point and span test calibration gas, we can also provide different kinds of gas sources.
A dynamic calibration device can be equipped with a built-in, programmable ozone generator. The ozone generator is used not only as an accurate and reliable calibration of ozone but also for g-d NO20 multi-point piecewise linear drive to ensure repeatability and accuracy of ozone concentrations; an optional spectrophotometer can also achieve the ozone generator's high accuracy control.

Ultrasonic Weather Monitoring Station
Vasthi's outdoor weather station measures wind speed and direction, air temperature, barometric pressure, and relative humidity. The wind measurement is performed using ultrasonic sensors, which means there are no moving parts to wear out or get caught in the rigging.
The WSO100 accurately measures wind speed and direction even when tilted, making it ideally suited for heeled sailboats or powerboats operating in pitching and rolling seaways.
When used with Vasthi displays DSM 150, DSM 250 N2KView, you can view apparent wind speed and direction, humidity, air temperature, barometric pressure (with graphs to see trends), wind chill factor, heat index, and dew point. If you add speed through water (DST110), GPS (GPS200), and compass (SSC300), you can view actual vessel-referenced wind speed and direction as well as ground-referenced speed and direction.
