      Dimensions27 cm (H) x 13 cm (W) x 10 cm (D)

      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
      • Micro controller Based
      • Highly Accurate and Fast
      • Useful for measuring any gas flow specially in G.C

            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.

                    COD Analyzer is a term used to measure the quality of effluent water. It is a measure of water pollution resulting from organic matter and is being extensively used by industry to test their waste water before releasing it to the environment.

                    COD Analyzer measure Chemical Oxygen Demand for waste water applications with the involved measuring principle based on UV light absorption through unsaturated organic molecules at 254nm. Here, the generated COD of the effluent is critical in respect to environmental requirements in many chemical and food based industries. The COD analyzers offered comes with latest technology support as well as delivering fast and reliable on-line measuring that is required for effectively monitoring COD level in waste water. Some of the standard feature of these analyzers includes measuring method based upon JIS K0806 "chemical oxygen demand (COD)” automatic measuring instrument, allowing reagent consumption to be saved to the limit and controlling temperature of reaction solution through oil bath temperature control that ensures temperature is almost not affected by operation temperature.

                    We specialize in the designing and manufacturing of CO2 Gas Purity Testers, which are designed by experts. The improvisation of many efficient features has made our CO2 Gas Purity Testers highly beneficial for various industrial applications Renowned for :Eliminating confusing cocks Hose connections Awkward manipulation Usual caustic spillage Making gas testing simple Cleaning Providing accuracy.

                     

                    Applications:

                    • Industrial Gas Industry
                    • Brewing Industry
                    • Distilling Industry
                    • Beverage Industry

                     

                    Operating Instructions:

                    • Caution: Caustic solution is used in the operation of this instrument.
                    • This solution may cause severe burns to the operator if not handled with care.
                    • Wear goggles and protective clothing while operating this instrument.
                      Preparation of Caustic Solution: A 20% solution of either Potassium Hydroxide or Sodium Hydroxide is recommended for air testing
                    • To make a 20% solution slowly add 100 grams of Potassium or Sodium Hydroxide crystals to 500 cc's of distilled water and store in a sealed jar.
                    • The Hydroxide solution may also be purchased from any laboratory or chemical supply company.
                    • A weaker solution may be used, but the tests will take longer and fewer tests can be performed.
                    • How To Operate :
                    • Attach a hose from the CO2gas supply that is to be tested to the nipple of the absorption burette.
                    • Use care when attaching the hose so as not to break the calibrated stem of the absorption burette.
                    • If using the 1/100th calibrated burette (10102) place your finger on top of the stem and push gently downward onto the support block to prevent the stem from breaking when attaching the hose. Make sure that the gas supply is regulated to below 10 psi before releasing gas into the Purity Tester.
                    • Open both cocks (5005) and allow the gas to sweep through the absorption burette and caustic reservoir to completely displace air in the glassware. If preferred, the bulb may be first filled with water and the water displaced with the gas to be tested.After the sample has been taken, close the cock on the absorption burette first and then close the cock on the caustic reservoir.Pour the caustic solution into the reservoir to the line indicated on the bulb (approximately 105 cc).
                    • Open the cock on the caustic reservoir and allow the solution to flow down into the absorption burette. Absorption of the CO2 gas now takes place until only air in the sample remains, the small bubble of which may be moved around by tilting the Purity Tester slightly, thereby insuring complete absorption of the gas.
                    • Close the cock on the caustic reservoir and turn the instrument 90 degrees so that it rests on its other frame side. In this position, the unabsorbed gas enters the calibrated neck where the volume is directly indicated.
                    • The percentage purity of CO2 gas is 99% plus 1/10 of 1% for each division as indicated by the level above the bottom graduation (Using the standard absorption burette #10101). There are our other types of absorption burettes available which are listed below.After the test is completed, empty the caustic solution from the Purity Tester.
                    • Place the Purity Tester over a container and open both cocks to allow the caustic to drain out.
                    • Rinse out all traces of caustic with warm water and dry the glassware before returning the tester to its case.
