Dual-made industrial dissolved oxygen meter DOG-2082D

DOG-2082D dual-channel industrial dissolved oxygen meter ?? DOG-2082D Industrial Oxygen ceremony I produced the highly intelligent line monitoring instrument. DOG-208F can be equipped with polarographic electrodes automatically from ppb to ppm level of a wide range of measurement, it is to test the boiler feed water, condensate, environmental protection, sewage and other industry-specific equipment liquid oxygen content measurement. DOG-2082D two-channel dissolved oxygen meter Main features: Chinese liquid crystal display, Chinese menu. Between the two channels are independent, non-interfering Microprocessor: ????????????? high-performance CPU chip, high-precision AD conversion technology and SMT technology, complete the multi-parameter measurement, temperature compensation , automatic conversion range, instrument self-test, high accuracy and good reproducibility DC + pulsed polarization voltage: greatly enhances the stability of advanced data processing methods to measure low concentrations of: a hundredfold reduction of the deformation of the membrane, temperature and affect the flow changes on the measured value of responsive, zero stability, drift pre-permeable membrane long life, easy to replace waterproof and dustproof design: protection class IP65, suitable for outdoor use DOG-2082D two-channel dissolved oxygen meter Technical Specifications: 1, Chinese liquid crystal display, Chinese menu operation; 2, measuring range: ???????????? 0 ~ 100.0 ug / L; 0 ~ 20.00 mg / L (automatic switching); 0 ~ 60 ℃ acuity : ???????????? 0.1 ug / L, 0.01 mg / L, 0.1 ℃ 3, the whole basic error: ???????? ug / L: ± 1.0% FS; mg /L:±0.5%FS, temperature: ± 0.5 ℃ 4, the whole Repeatability: ?????? ± 0.5% FS 5, the stability of the whole value shown: ???? ?? ± 1.0% FS 6, automatic temperature compensation range: ???? 0 ~ 60 ℃, 25 ℃ as a benchmark 7, response time: ???????????? <60 seconds (final value of 98%, 25 ℃ ) 37 ℃: 98% final value <20 seconds 8, between two channels: ??????????? independently without disturbing each other 10, the output current error:? ??????? ≤ ± 1.0% FS 11, isolated outputs: ????????????? 0 ~ 10 mA (? load resistance <1.5KΩ) ???? 4 ~ 20 mA (load resistance <750Ω?) 12 , continuous power-down data retention time: 10 years 13 ??? power source: ??????????? 220VAC ± 10% ?, 50 ± 1HZ; optional DC24 ± 2.4V, 1A power supply 14 Dimensions: ??????????? 146 (L) * 146 (W) * 108 (D) mm hole size:? ??????????? 138 * 138mm 15 , the amount of weight ???: ???????????? second table: 0.8Kg 16, the working conditions: ???????????? ambient temperature: 0 ~ 60 ℃?
