BC-2012 YL (vehicle-mounted refrigerated) water quality automatic sampler is a special environmental monitoring instrument used for surface water and sewage sampling, water source monitoring, pollution source investigation and total amount control. It adopts the international general peristaltic pump water mode, controlled by single chip controller. The timely mixed water samples can be collected according to the needs of users to meet the sampling requirements in HJ / T91-2002 Technical Specification for Surface Water and Sewage Monitoring issued by the State Environmental Protection Bureau. One of the necessary instruments for environmental monitoring and monitoring stations at all levels to carry out water pollution monitoring work and environmental protection research departments to carry out research work.
The water quality automatic sampler is suitable for environmental monitoring stations, water conservancy and hydrology, labor health, scientific research institutes and other departments at all levels. It is equipped with on-board compressor refrigeration refrigerator to meet the needs of sampling and refrigerated storage of waste water from river, river, lake, sea and industrial pollution sources.

Need to choose the flowmeter probe, 1~9999 cubic meters of water arbitrarily set, increment of 1 cubic meter Pulse trigger sampling: 1~9999 pulses arbitrarily set, increment of 1 pulse. The received pulse was passive, with a closure time greater than 1 second |
| Sampling pump characteristics |
Sampling flow rate: 1,800 mL / min Inner diameter of the pump pipe: 10 mm Pump tube material: high-strength medical silicone tube Pump assembly material: the pump body is reinforced engineering plastic, fast disassembly module combination, motor shaft, pump pipe roller support is made of stainless steel Sample volume error: ± 5% Sampling repetition accuracy: ± 5 mL Vertical lift: 8m Horizontal suction range: 50 m Air tightness of pipeline system: -0.085MPa |
| software function |
Operation interface: large screen 2.8 TFT color LCD screen, all Chinese menus, man-machine dialogue mode, need human intervention when the Chinese prompts Bottle sampling: * The instrument can realize 1-12 bottles of vial sampling, the number of bottles can be freely set up, the distribution system self-lubrication, positioning self-locking type Pipeline cleaning: moisten the pipeline by "blowing-suction-blowing" to avoid cross contamination of samples Software password lock: it can protect the program set in the instrument from being modified Fault alarm: the interface alarm after the instrument is uncontrollable and affects the use Sampling program preset: 10 common working programs can be preset and stored according to the sampling requirements, which can be called directly later External pump control: the sampling distance can be extended by controlling the external submersible pump or self-priming pump Power failure protection: power failure restart, stored parameters and data are not lost. The running program is going back to the last run state History record: Sampling record: sampling quantity, sampling bottle number, sampling time. It can store 5,000 bars Flow record (after selecting a flowmeter): instantaneous flow, cumulative flow, and time. Can store 60,000 bars Communication interface: internal MODBUS protocol, 1-channel RS232 / RS485 digital interface (default RS232) Simog input 14 ~ 20 mA, 12 bit resolution Switch quantity input 1 channel passive Switch quantity output 1 active, 15VDC / 200 mA |
