Brief introduction: Widely used in surface water (river, lake, reservoir), the source of drinking water, tap water pipe network, such as automatic and continuous monitoring for water quality, the service in the department of environmental protection, water companies, large and medium-sized enterprises, etc. Features: 1. The ammonia gas sensitive electrode standard addition method is used, convenient and quality control, even if the ammonia nitrogen content is very low also can realize accurate measurement; 2. The reagent consumption, less maintenance, price and maintenance cost is low; 3. Positive liquid road maintenance, with automatic sampling and self-cleaning function; 4. Select Chinese interface, simple to use, easy to operate; 5. The monitoring parameter is set by verification value, accurate check every measurement data, real-time understand the equipment running status, to judge of the effectiveness of the testing data; 6. Extensible function (in instrument increase of sample pretreatment, elimination of interference in accessories or reserved parts location), ensure the normal order of the instrument can be long-term steady running; 7. Independent storage capabilities, stored data safe and reliable; 8. Reliable data transmission, integration of a variety of means of transport, with 4-20 ma analog output (4), 8 DI digital quantity input and RS485/232 data interface, at the same time support the MODBUS data processing way to access and control machine; 9. Wide measuring range, can automatic switching range, broaden the scope of the instrument, can be used in surface water, drinking water, can be applied to on-line monitoring on pollution sources such as; Technical parameters Detection principle: standard addition method of ammonia gas sensing electrode Detection period: 10min~30min Measurement range: 10.0~100, mg/L 100~1000, mg/L 0.00~10.0mg/L Minimum detection limit: 0.03 mg/L Repeatability error: 5% Zero drift: + 5%FS Span drift: plus or minus 5% FS Response time: < 3 min Temperature compensation accuracy: within + / - 0.1 mg/L MTBF: p 720 h/time Actual water samples than in testing: plus or minus 10%
