The GW11 type pipeline network sampler is a dedicated sampling instrument for pipeline networks launched by our company. It adopts the internationally common peristaltic pump water extraction method and operates under the control of a single-chip microcomputer. To facilitate underground work, the sampler is equipped with a 45.6Ah large-capacity lithium battery externally.
Users can input the sampling time interval, sampling volume and sampling method as needed. It can automatically complete the corresponding work online. After being equipped with a flow sensor, it can achieve dual functions of sewage measurement and sampling in proportion to the flow rate. It can be remotely and wirelessly controlled, and sampling instructions can be randomly issued as needed. So as to obtain the most genuine and effective water samples. It is one of the essential instruments for environmental protection monitoring departments to enhance work efficiency, reduce labor burden, and ensure the accuracy and validity of monitoring data.
Compact in size and easy to operate, it can be used in scenarios such as pipes, ditches, deep Wells and manholes.

Sampling method |
Standard sampling: Sampling delay time: (1 to 9999 minutes) can be set arbitrarily, with an increment of 1 minute; Sampling interval time: (1 to 9999 minutes) can be set arbitrarily, with an increment of 1 minute; Sampling volume: (5-500 ml) can be set arbitrarily, with an increment of 1 ml;
Mixed sampling: Sampling delay time: (1 to 9999 minutes) can be set arbitrarily, with an increment of 1 minute; Sampling interval time: (1 to 9999 minutes) can be set arbitrarily, with an increment of 1 minute; Sampling volume: (5-500 ml) can be set arbitrarily, with an increment of 1 ml; Number of mixed samples: (1 to 100)
Parallel sampling: Sampling delay time: (1 to 9999 minutes) Arbitrarily set, with an increment of 1 minute; Sampling interval time: (1 to 9999 minutes) can be set arbitrarily, with an increment of 1 minute; Sampling volume: (5-500 ml) can be set arbitrarily, with an increment of 1 ml; Number of parallel samples: (1 to 6) |

Characteristics of the sampling pump |
Sampling flow rate: 480mL/min; Pump pipe inner diameter: 10 mm; Pump tube material: High-strength medical silicone tube; Pump assembly material: The pump body is made of reinforced engineering plastic, and the quick-disassembly and assembly modules are combined. The motor shaft and pump pipe roller bracket are made of stainless steel. Sampling volume error: ±5% Sampling repeatability accuracy: ±5 mL Vertical head: 8m Horizontal suction lift: 50 m Air tightness of the pipeline system: ≤-0.085MPa; |

Software functions |
Operation interface: Large 2.8TFT color LCD screen, all Chinese menus, human-computer dialogue mode, and Chinese prompts when human intervention is needed. Bottle division sampling: The instrument can achieve bottle division sampling from 1 to 6 bottles, with the number of bottles freely set. The distribution system is self-lubricating and self-locking in position. It adopts a direct water injection type to avoid cross-contamination of water samples caused by the flow diversion of the flow guide plate. Password lock: Software password lock, which can protect the programs set inside the instrument from being modified. Power-off protection: Restart after power failure, and the stored parameters and data will not be lost in case of power failure. The running program is restored to the state of the last run. Historical Record: Sampling record: Sampling volume, sampling bottle number, sampling time. It can store 5,000 items. Sensor records: COD, PH, turbidity. It can store 6,000 items (corresponding sensors need to be selected). Communication interface: Internal MODBUS protocol, 1 RS232/RS485 digital interface (default RS232); Analog input 1 channel 4~20mA, 12-bit resolution; Switch input 1 passive channel; Switch output 1 active channel, 15VDC/200mA; |
