Sherwood Scientific Model 360 Flame Photometer
Latest five element (Na, K, Li, Ca, Ba)
Ergonomic design with front loading,
With ease of use resulting from auto ignition and flame optimisation.
Safety features including fail safe flame detection and shut off, with low air pressure indicator
High sensitivity with fine manual control of air, and stable flame design
And ease of maintenance and storage
The Model 360 Flame Photometer is a LOW COST, single channel, five element, analogue output and digital display Flame Photometer. It has inherited a great deal from our well respected, higher priced models.
The Model 360 Flame Photometer's mixing chamber, burner stem and burner head are taken from our world renowned Model 410 Flame Photometer. Automatic flame optimisation comes from our Dual Channel Flame Photometer Model 420 series of instruments.
Put simply, the Model 360 Flame Photometer is a new product built with tried and tested components where it really matters. It has the best limits of detection available from a low cost instrument and precision comparable to higher cost instruments.
The five element filter stick is easy to remove for cleaning and filter replacement. The mixing chamber, burner head and burner stem come apart for cleaning with no tools required. Electronics and pneumatics come in separate "pods" and both are easily removed from the main instrument chassis; offering a potentially huge saving on shipping costs if a return to base repair or replacement becomes necessary.
The appropriate filter for the element to be analysed is selected using the filter stick and indicated by LEDs on the front panel, which also displays flame status by LED. A display "hold" button allows readings to be captured until recorded - useful if you are unexpectedly called away. For ease of operation, the air regulator is accessible and pressure gauge visible at the front.
A large sample work area is also provided in a spill containment tray which is easy to remove and clean. The instrument is supplied ready for use following installation of the chimney. Connection to the mains power supply is easy; each unit is supplied with a universal switch mode power supply with its own multi-plug adapter kit; no need to worry about voltage selection or making up power cords.

For optimum performance the Model 360 Flame Photometer should be warmed up for 30 minutes.
Na, K & Li Interference is <0.5% value of element under analysis.
<1.5%* CV for 10ppm K set to 1000. (20 aliquots sampled for 20 seconds each from a single sample) Reading taken 20 seconds after introduction and with a Blank aspirated for 10 seconds between each standard reading.
<1.0%* CV for 20 consecutive readings taken at 20 second intervals without removing the uptake tube from a 10ppm Potassium solution Set to 1000.
