| Sampling method | Standard sampling: Sampling delay time: (1 ~ 9999 minutes) arbitrarily set, increments of 1 minute Sampling interval time: (1 ~ 9999 minutes) arbitrarily set, increments of 1 minute Sampling volume: (5 ~ 500 mL) arbitrarily set, increment of 1 mL Mixed sampling: sampling delay time: (1 ~ 9999 minutes) arbitrarily set, increments of 1 minute Sampling interval time: (1 ~ 9999 minutes) arbitrarily set, increments of 1 minute Sampling volume: (5 ~ 500 mL) arbitrarily set, increment of 1 mL Number of mixed samples: (1 ~ 20) Parallel sampling: sampling delay time: (1 ~ 9999 minutes) arbitrarily set, increments of 1 minute Sampling interval time: (1 ~ 9999 minutes) arbitrarily set, increments of 1 minute Sampling volume: (5 ~ 500 mL) arbitrarily set, increment of 1 mL Number of parallel samples: (1 ~ 12) Flow-triggered sampling: A dedicated flow meter controls sampling. Optional ultrasonic liquid level sensor is required, 1 ~ 9999 cubic meters of water can be set arbitrarily, with an increment of 1 cubic meter Pulse trigger sampling: 1 ~ 9999 pulses can be set arbitrarily, with an increment of 1 pulse. The received pulse is a passive pulse with a closing time greater than 1 second |
| Sampling pump characteristics | Sampling flow rate: 1800 mL/min Inner diameter of pump tube: 10mm Pump tube material: high-strength medical silicone tube Pump assembly material: The pump body is made of reinforced engineering plastic, quick disassembly module combination, motor shaft and pump tube roller bracket are made of stainless steel Sampling error: ± 5% Sampling repeatability: ± 5 mL Vertical lift: 8m Horizontal suction lift: 50m Air tightness of pipeline system: ≤-0.085 MPa |
| Software features | Operation interface: Large screen 2.8 TFT color LCD screen, all Chinese menus, man-machine dialogue mode, Chinese prompts when human intervention is required Separate sampling: The instrument can realize separate sampling of 1-12 bottles, the number of bottles can be set freely, and the distribution system is self-lubricating, positioning and self-locking Pipeline washing: The pipeline is washed by "blowing-suction-blowing" method to avoid cross-contamination of samples Software password lock: It can protect the program set in the instrument from being modified Fault alarm: When the instrument has an uncontrollable fault that affects the use, the interface alarms Sampling program preset: 10 common working programs can be preset and stored according to sampling requirements, and can be directly called later External pump control: The sampling distance can be extended by controlling the external submersible pump or self-priming pump Power-off protection: restart after power-off, the stored parameters and data will not be lost after power-off. The running program reverts to the state of the last run Sampling record: sampling time, sampling status, sampling bottle number. Can store 5000 items Flow records: time, instantaneous flow, cumulative flow. Can store 6000 pieces (optional ultrasonic liquid level sensor required) Communication interface: internal MODBUS protocol, 1 channel RS232/RS485 digital interface (default RS232) Analog input 1 channel 4 ~ 20mA, 12 bit resolution Switching input 1 passive Switching output 1 active, 15VDC/200mA |
