It can measure the concentrations of K+, Na+ , Cl- and Ca++ and pH values. Applies ISE (Ion Selection Electrode), which gives instrument the advantages of minimum maintenance, easy assembly & disassembly, as well as stable and reliable measurements. Working Modes o Normal mode automatic calibration this mode adapts to large and middle scale hospital with large sample volume sleep functions which can save reagent o Saving mode: 24 hours reagents consumption is only 7ml when it does not measure. This mode. adapts to hospital with small sample volume. Each test channel can be closed separately, So it is convenient to do emergency measurement. 110mm~60mm LCD display, automatic screen saver, friendly interface, easy to operate Mini thermal printer can print repeatedly at any moment. It is convenient to feed paper. And the print is very clear. Revising datas automatically to ensure the accuracy of data. It can save1500 test results, data will not be lost even if the power is cut off. Users can inquire or print at any moment. The instrument is equipped with a RS232 serial port, which can be connected to computer. It may collect, manage and print measure result by relevant software. 10 It has electrode-checking function. Users can do corresponding maintenance according to checking result Exempt of routine maintenance, this greatly lighten the burden of operators; In-side software self-checking can suggest users eliminate malfunction in time. Advanced and reliable fluid position examination technology can save reagent Adopt built-in operating system leads to a reliable performance. Users can modify each setting to meet different requirements The quality-control inspecting function can track the accuracy of the instrument.Test items and specification Test Object Linearity Repeatability(Cv) Stability Accuracy K+ }0.3mmol/L .1.0 % }0.2mmol/L/h }0.3mmol/L Na+ }3.0mmol/L .1.0 % }2.0mmol/L/h }3.0mmol/L Cl- }3.0mmol/L .1.0 % }2.0mmol/L/h }3.0mmol/L Ca++ }0.2mmol/L .2.0 % }0.2mmol/L/h }0.2mmol/L pH 1.0 % }0.02/h Standard Ca++ and Total Ca++(calculating value) Sample Serum, Whole Blood, Plasma, Diluted Urine Sample Volume 90ul Testing Time.50s Temperature 10-30, humidity 85% Power Supply Voltage AC160V-245V 50}1Hz Volume 260mm~260mm~ 340mm Weight 6Kg Packing Details 355mm~350mm ~420mm N.W.7 kgs G.W.10kgs Reagents Calibration solution 500 ml ~3 Slop solution 500 ml Saturated KCL solution 10ml Protein-removing solution 5ml dilute Electrode solution 10ml.
