Gas Instruments

Principle:

The SMART FLOW 20 is based on the classical method viz. soap film method. The instrument is automated by using micro controller, which provides highly accurate measurement and direct digital read out of gas flow rate. The time required for the soap film to pass through a known fixed volume is measured. The soap film is sensed by IR sensor. When the soap film passes through first sensor, it activates the timer of micro controller. Timer is stopped when the film crosses the second sensor. The flow rate is then calculated by micro controller and instantly displayed in cc/min.

Features:

Direct Digital Readout

Carbon monoxide (CO) is a deadly, colorless, odorless, poisonous gas. It is produced by the incomplete burning of various fuels, including coal, wood, charcoal, oil , kerosene, propane, and natural gas. Products and equipment powered by internal combustion engines such as portable generators, cars, lawn mowers, and power washers also produce CO. Carbon monoxide is harmful when breathed because it displaces oxygen in the blood and deprives the heart, brain, and other vital organs of oxygen. Large amounts of CO can overcome you in minutes without warning-causing you to lose consciousness and suffocate.

Product Description
Gas-mini portable gas detector are designed to keep personnel safefrom atmospheric gas hazards and allow mobile testing of locations before they are entered. Gas-mini portable gas detector is carried or worn by individual. Gas-mini portable gas detector is battery operated and used to check toxic, combustible gas and oxygen level before entering confined spaces.
Gas-mini portable gas detector is an industrial-grade portable single gas detector. Its compact & rugged design is meant to withstand harshenvironments while providing ease of use in a critical hazardous atmosphere. Gas-mini portable gas detector comes in three gas variants oxygen (o2), hydrogen sulphide (h2s) and carbon monoxide (co2).

How does a Gas-mini Portable Gas Detector work?
Gas-mini portable gas detector use a sensor to measure concentration of individual gases in the atmosphere. The sensor serves as a reference point and scale, generating a measurable electric current when a chemical reaction caused by a specific gas occurs. The use of a gas monitoring system, with appropriate action taken if dangerous levels of gases are detected, can help to prevent an explosion or can help to prevent worker injury or exposure to toxic gases.

Key word :

Ultrasonic Leak Detectors can be used for a wide variety of tests including airborne measurements for gas leaks, compressed air, steam traps, bearings, pump cavitation detection, vehicle windscreen leaks, window and roof leaks etc.

Gas Sensors, Detectors and Monitors with alarms.

Gas leak detectors, Gas Analysers as well as gas sensors interact with a gas to initiate the measurement of its concentration which could be used to sound an alarm. The gas detector of gas sensor then provides output to a gas instrument to display the measurements. Common gases measured by gas detectors and gas sensors include ammonia, aerosols, arsine, bromine, carbon dioxide, carbon monoxide, chlorine, chlorine dioxide, Diborane, dust, fluorine, germane, halocarbons or refrigerants, hydrocarbons, hydrogen, hydrogen chloride, hydrogen cyanide, hydrogen fluoride, hydrogen selenide, hydrogen sulfide, mercury vapor, nitrogen dioxide, nitrogen oxides, nitric oxide, organic solvents, oxygen, ozone, phosphine, silane, sulfur dioxide, and water vapor.

Important measurement specifications to consider when looking for gas detectors and gas sensors include the response time, the distance, and the flow rate. The response time is the amount of time required from the initial contact with the gas to the sensors processing of the signal. Distance is the maximum distance from the leak or gas source that the sensor can detect gases. The flow rate is the necessary flow rate of air or gas across the gas detectors or gas sensors to produce a signal.
