Digital Flame Photometer Meter

Drawing on the information in the "sky price list 1124.pdf" [NEW SOURCE], here is the product description and specification for the Digital Flame Photometer Meter, presented with a table, followed by frequently asked questions: Digital Flame Photometer Meter The Digital Flame Photometers manufactured by Sky Technology India boast of top-notch quality. Supreme quality raw materials and properly updated technology are utilised for their manufacturing. Their highlights include durability, longevity, strength, and perfect designs. Top-notch quality experts, R&D teams, and engineers develop these products with the latest trends in mind. The Microprocessor Flamephotometers are used for the determination of Sodium (Na), Potassium (K), Calcium (Ca), and Lithium (Li), and also Barium (Ba). They utilise the latest Microcontroller technology and advanced engineering techniques to give enhanced accuracy and reproducibility. These meters have soft-touch membrane keys for ease of operation. The solution is aspirated through an atomiser; air, sample, and fuel are mixed in the mixing chamber, which is then sprayed as a very fine mist into the flame. Some models are microprocessor-based with printer interface and offer features like four measurements in a single aspiration setup, storage facility, sample data storage, curve calibration programmability using up to 25 standards, multiple calibration curve saving, and data processing through curve fitting techniques. Here are the technical specifications for the mentioned models:

Frequently Asked Questions:

• What elements can be measured using the Digital Flame Photometer Meter? The Digital Flame Photometer Meter can be used for the determination of Sodium (Na) and Potassium (K) as standard. Calcium (Ca) and Lithium (Li) are often available as optional filters or measurements. Some models, like the Microprocessor Flame Photometer Meter (Sky-486), can also measure Barium (Ba).
• What is the accuracy of the measurements? The accuracy varies between models. For the Digital Flame Photometer Meter (Sky-471), the accuracy is ±2% up to 40 ppm and ± 5% above 40 ppm. The Microprocessor Flame Photometer Meter (Sky-486) has an accuracy of ±2% ±1 digit and a curve fit accuracy of <2% error when specific standards are used.
• Do I need a separate air compressor? Yes, the Microprocessor Flame Photometer Meter (Sky-486) typically requires an oil-free mini compressor unit with a pressure regulator for the air supply to the flame. While not explicitly stated for the Digital Flame Photometer Meter (Sky-471) in terms of an included compressor, a dry oil-free air supply is required, which might necessitate a separate compressor.
• Is the meter easy to operate? Yes, both types of Digital Flame Photometer Meters are designed to be simple and easy to operate, with the Microprocessor model (Sky-486) featuring soft-touch membrane keys.
• Can I connect a printer to the meter? Yes, the Microprocessor Flame Photometer Meter (Sky-486) has a provision for attaching a dot matrix printer or HP LaserJet/inkjet (non-windows) printers with a Centronics parallel interface. It also has an RS-232C interface available. The Digital Flame Photometer Meter (Sky-471) does not explicitly mention printer connectivity in this description.
• Does the meter store calibration curves or sample data? The Microprocessor Flame Photometer Meter (Sky-486) has a storage facility for sample data and allows for curve calibration programmability using up to 25 standards with the ability to store multiple calibration curves. The Digital Flame Photometer Meter (Sky-471) does not mention these storage capabilities.
• What type of flame does the meter use? Both models utilise an LPG (Liquefied Petroleum Gas) fuel source and require a supply of dry oil-free air to produce the flame.
• What are the power requirements for the meter? Both the Digital Flame Photometer Meter (Sky-471) and the Microprocessor Flame Photometer Meter (Sky-486) operate on 230V, ±10% AC, 50 Hz.
