Medical flame photometer with digital display

The Fater Electronic 620C digital flame photometer is built for medical diagnostic laboratories. Its technical specifications and performance are exactly like those of the Corning instruments of England. Two digital displays show the sodium, potassium and lithium results and one display shows the memory values; the test result is read directly from the display. The device is supplied with a standard solution and an air compressor.

This device comes with a three-year warranty and ten years of after-sales service. Its installation and commissioning are free, and the supply of its spare parts is guaranteed for ten years.

Control system

• Automatic calibration: Blank and standard calibration is automatic and needs no manual adjustment.
• Memory: The device has 100 memories for storing sodium, potassium and lithium results.
• Keypad: A membrane keypad with device status indicators makes the device easy to work with.
• Processor: The hardware is built with an AVR microcontroller and software designed by the company's own specialists.
• Controls and indicators: An on/off switch with a power lamp, a triple seven-segment display for the sodium, potassium and lithium results and the memory number, a fuel adjustment screw, Zero, Cal and Measure keys with a flashing lamp, lamps for flame on, no air and no gas, and an air regulator on the back of the device.

Measuring system

• Filters: Sodium and potassium filters are supplied with the device.
• Reading range: Sodium 0 to 200 mmol/L, serum and plasma potassium 0 to 10.0 mmol/L, urine potassium 0 to 200 mmol/L and lithium 0 to 3.0 mmol/L.
• Display resolution: Sodium 1, potassium 0.1 and lithium 0.1 mmol/L.
• Linearity: Serum and plasma sodium (110 to 170 mmol/L) ± 2 mmol/L, urine sodium (0 to 200) ± 3, serum and plasma potassium (0 to 10.0) ± 0.2, urine potassium (0 to 200) ± 2 and serum and plasma lithium (0 to 3.0) ± 0.2 mmol/L; each value plus one unit of the last digit.
• Repeatability: Based on 20 repeated measurements in 10 minutes, the coefficient of variation is better than 0.6 % for sodium at a level of 140 and potassium at a level of 5.0 mmol/L, better than 1.5 % for potassium at a level of 80 and better than 1 % for lithium at a level of 2.5 mmol/L.
• Mixing chamber: The new mixing chamber is designed on past experience and with a new formula. Less fluctuation, no breakage and ease of use were the main aims of its design.
• Air compressor: An Oil Free compressor, model 850, made by the company itself, with an Italian electric motor, is supplied with the device. Its air flow is 6 L/min at a pressure of 14 psi, and its maximum outlet pressure is 22 psi.

Options

• Lithium filter: The lithium filter is ordered separately.
