Wireless Gas Detector

Vasthi Instruments Wireless Gas Detector provides a powerful and high accuracy measuring equipments and we are supplying these wireless gas detector equipments world wide. We are the first in India to develop the Wireless gas detector equipments. Vasthi Designs Wireless Gas detector as per specific users requirement and vasthi provides range of transmission from 50 meters to 3-4 km. Different frequency module is used for Wireless Transmission. Vasthi Wireless Gas Detector operates on LI-ION battery and this battery backup life time is up to 7 days and providing you in built rechargeable circuit . If not found any socket near to the Wireless Gas Transmitter installed area for charging battery in this case we are happy to provide “Solar Plate” for charging battery. Wireless Gas Detector is easy to carry and movable. Micro controller based system with alarm for measuring concentration of all gases in line. Wireless gas detector sensor (detector) senses the gas concentration and transmits a proportionate signal to the digital monitor. Modern integrated circuits provide all needed indication, alarm, and fail safe functions with simplicity of installation and operation. Monitor is built into a protective rigid Aluminium case. A window on the front face allows visibility of digital LCD indicator. LED alarm lights are provided on the left side of digital meter for individual gases, and below the meter is the manual push button switches for reset and for various functions as explained below separately. The electronic components and integrated circuits are mounted on a single printed circuit board.

Portable Confined Space Monitor

Vasthi Instruments Portable Confined Space Monitor offers the latest and most innovative monitors available for confined Space Entry (CSE). Data logging is an option on all our multi-gas monitors Atmospheric hazards in a confined space are those that expose entrants to risk such as death, entrapment, injury, or acute illness from one or more of the following causes of gas detector.

Portable Explosive Meters

Vasthi Instruments (Model VS-70 E) HANDHELD PORTABLE COMBUSTIBLE GAS DETECTOR is a compact battery operated portable instrument used for taking an air sample and indicating the presence and concentration of combustible gas. Samples of the air under test are drawn by means or a rubber aspirator bulb and analyzed for combustible gas content on a heated platinum filament in a Wheatstone bridge measuring circuit. A built-in meter indicates combustible gas content in units of explosibility. Power for operation or the instrument is provided by Lithium-ion batteries. A probe and extension hose permit withdrawal of samples from remote locations and the instrument fits in a compact leather case with over the shoulder carrying strap. The model VS-70 E is suitable and recommended for testing tanks, manholes, vessels, pressure cylinders, pipelines, and other closed systems or confined spaces to determine the presence or absence of combustible gas. It is a valuable aid for the safety of operations whenever combustible gases or vapors are handled.

Multi Gas Detectors

Vasthi Instruments Multi-Gas Detector is specially designed to analyze any gas of your choice, its automatic operation, accurate measurement, and crystal clear digital display makes this Gas detector design more users friendly. Moreover, Multi-Gas Detector acts effectively in the on-site instant analysis. Gas detector’s portability makes it more comfortable for a user it was designed in such a way it provides all immediate necessary data that is required to analyze any type of gas in no time, its computer interface stores key data that can be analyzed in the laboratory.

Single Gas Detector

Vasthi Instruments Single gas detector is a device which 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. This single gas detector can also sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave the area. This type of single gas detector device is important owing to the fact that there are many gases that can be harmful to organic life, such as humans or animals.
