Features: 1 automated testing process: dilute, add alkali, distillation automatically, without human intervention; 2 solvent intelligent adding technology: can be set in batches, time-sharing, quantitative addition of alkali and sample dilution water, to prevent the occurrence of the sample bumping to prevent the lye and sour gas thoroughly to prevent titration system to improve the measurement accuracy and stability Sex 3 with all PTFE diaphragm pump, reliable quality, add fluid accurate, completely eliminate the alkali pump crystallization blockage. And compared to pressurized air pump to add solvent, easy to change the solution thoroughly absorbed, more visualization, higher efficiency; 4 experimental pipeline can be set free to clean the program, easy to use; 5 built-in multiple high-precision sensors, can be achieved in place, set the nitrogen pipe in place, condensate detection, to help users find the first time the experimental abnormal state, to ensure experimental safety; 6 all chemical resistant plastic shell, the whole small and beautiful, 4H hardness spray process. 7 Steam flow rate adjustable: automatic adjustment between 0-100%, can accurately control the steam flow, is very conducive to the stability of experimental results; 8 steam pre-added function: The order of addition of reagents can be programmed, that is, immediately after the introduction of dilution water in the digestion fluid through the steam, through the stirring effect of steam to make the concentrated sulfuric acid in the digestion solution is fully diluted to reduce the subsequent addition of concentrated alkali The reaction intensity, improve the distillation effect; 9 display control mode: large-screen touch color LCD display, quick and sensitive operation, easy to use; 10 experimental program configuration features: can store 500 sets of distillation experiment program; Technical Parameters: Measurement range: 0.1-250mgN (milligram nitrogen); Determination of speed: 3 - 8 minutes / sample; Distillation time: 0-999min can be arbitrarily set; Determination of sample weight: solid ≤ 5g; liquid ≤ 20mL; Repeatability: 0.5% relative error; Recovery: 99.5% or more (1-220mgN); Experimental program storage: 500 sets; The original data storage: 1000 sets.
