Laboratory digester 6B-6C/6B-10C/6B-12S

Features The instrument adopts microcomputer technology to make sequential control heating mode, at the same time, can heat 6/10/12 sets of 250 ml conical value type of large grind (straight type of large grinding mouth) full glass and back flow device; achieving the purpose of energy saving, reducing power load and improving efficiency. Reagents and materials, analytical steps and the results of the COD used by the instrument fully comply with the latest national standard HJ 828-2017; Note: for determination of water samples with≦50mg/L COD, when the sample concentration is low, sampling volume can be appropriately increased; For determination of COD water > 50 mg/L, can be diluted by titration agent and oxidant to improve accuracy; For COD water > 700 mg/L, should be diluted water concentration to complete the result test; when the COD results< 100 mg, reserve to integer, when the COD results≧ l00mg/L, keep three significant figures; for water samples with high chloride ion conten. Technical specifications Measuring range:16~700mg/L、700~10000mg/L(need to dilute water sample) Measuring time:≦150 minutes Measuring error:Potassium biphthalate standard solution (500mg/L) and the relevant standard deviation are not more than 5.0%; industrial organic waste water (500mg/L) and relevant standard deviation are not more than 8.0% Environment temperature:-5~40℃ Display mode:Liquid crystal display Type of cooling:Air cooling (double fans) Batch sample:6 pieces/batches;12 pieces/batches;12 pieces/batches Digestion time:Can set time according to the requirement of users, 1-999 minutes The setting of fan:Self-motion/manual operation Working power supply:1200W (AC 220V±22V, 50HZ)
