LB-8001D portable water quality sampler Introduction: LB-8001D automatic water quality sampler also has password protection, power failure protection and other protection functions, which can realize sampling by timing, time, flow, external control sampling, serial port control and other methods, and can be equipped with remote control, and monitoring camera and other functions. characteristic: 1. Bottle separation and sample retention function: the instrument can achieve 1~30 bottles of bottle separation and sample retention, and the number of bottles can be freely set. 2. Sampling function: it can realize timing sampling, time ratio, flow ratio, external control sampling, serial port control and other sampling methods. 3. Sample retention record function: it can record the sample retention bottle number, sample retention time, sample retention volume, COD value and NH3-N value for each sampling, and can record 10000 new data records. 4. External interface: flowmeter analog interface, RS485 interface. 5. Power-off protection function: after the instrument is powered off and re-energized under the operating state, the instrument can automatically restore to the original operating state, and the instrument parameters will not be lost after the power failure. 6. Automatic emptying function: after each sampling, the system can automatically empty the water in the pipe to ensure that the sampling pipeline does not produce sediment blockage. 7. Anti-overflow function: the user can set the number of sample retention bottles, and stop sample retention after completing the set number of bottles. 8. Refrigeration function of water sample: adopt efficient refrigeration device, which can keep the retained water sample at 0 ℃~4 ℃. 9. Adopt built-in dual-pump sampling technology, with higher sampling accuracy; D special split sampling, sampling and flushing the pipeline at the same time, the water sample is more representative. Technical parameters: Sampling interval: 1min~9999min can be set Number of sample bottles: 12 bottles/30 bottles Single sample volume: 10ml~1000ml Sample bottle capacity: 900ml (PET bottle 1000ml) Sample retention error: ± 2ml (when the sample is 10ml); ± 2% (when the sample is 200ml) Error of equal proportion sample retention: ± 2% Suction head of built-in sampling pump: ≥ 6.5 m Horizontal sampling distance: ≥ 60m Storage temperature of water sample: 0 ℃~4 ℃ (± 1.5 ℃) Air tightness of pipeline system: ≤ -0.07MPa MTBF: ≥ 1440h/time Insulation impedance: ＞ 20M Ω Analog interface: 4mA ～ 20mA Digital input interface: switching value, RS485 Flow measurement access form: flowmeter analog signal Weight: 20kg Working voltage: AC220V ± 10%, 50Hz ± 1Hz Working temperature: 10 ℃~40 ℃ Working humidity: ≤ 85% RH
