Vasthi PM 10 and PM 2.5  Particulate Matter Monitors works Principle of Particulate matter10 analyzer uses the technology: Ambient particulate matter, Beta –ray detector for measuring the concentration Particulate matter whose aerodynamic equivalent diameter is smaller than 2.5/10μm on rolled filter tape. The instrument adopts low-radiation C14 as the radioactive source. The emitted β-ray passes through the filter membrane with contaminants and will be received by the detector. The detector[1] is composed of a photo-multiplier tube (or Geiger detector), plastic scintillator, and 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 concentration in the air can be calculated received, and then the pm 2.5 and pm 10 concentration in the air can be calculated.

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 VDOM Series Online Dew Point Meter is a microcontroller-based precision instrument to help ensure the optimum operation of drying equipment. An online dew point meter by Vasthi Instruments is ideal for precise monitoring of dew point temperatures(°C Td) in air/gas output from dryer systems and processes. embedded with micro-controller-based circuits to give a direct read-out in dew point (°C Td) or other units corresponding to sensor output based on psychometric equations. To achieve high accuracy, it uses temperature compensation over the complete operational range.

A portable dew point meter by Vasthi Instruments is a hand-held, light weight, portable, and affordable dew point meter that is an easy-to-carry, battery-operated measuring tool. The portable dew point meter has an operating pressure of up to 20 bar and a moisture measuring range of 0–23000 ppm. The device has an incredible battery life, up to 20 hours on a single charge. The instrument is assembled in a rugged handheld IP65-protected plastic enclosure and equipped with quick-disconnect tubing couplings and an internal sensor manifold.

Single-Gas Detector is a device that detects the presence of any gas within an area, usually as part of a safety system. This type of Single-Gas Detector Equipment is used to detect a gas leak and interface with a control system so a process can be automatically shut down. A gas detector can also sound an alarm to operators in the area where the leak is occurring, allowing them to leave the area. 

VM-4 AS Multi-gas detectors can detect multiple gases with a single detector. The multi-gas detector can detect combustible gas, O2, and other two types of toxic gases continuously and simultaneously. It is widely used in areas where explosion-proofing is required or toxic gas leaks, like underground channels or the mining industry, to protect the worker`s life and avoid damage to the relevant equipment.
