The SZ-CY-A24C (split refrigerated) water quality automatic sampler is an environmental monitoring instrument launched by our company for automatic sampling at wastewater discharge outlets. It uses a dedicated peristaltic pump for sewage to extract water, with a large pipe diameter and fast flow rate, which can effectively avoid pipeline blockage. Under the control of a 32-bit high-performance industrial grade ARM controller, the sampling method, sampling time interval, sampling amount, and storage location can be arbitrarily set according to user needs. After being connected to a flow sensor (optional), it can achieve dual functions of sewage metering and proportional sampling according to the flow rate. It can be connected to online monitoring instruments to achieve excess sample retention and remote wireless control. Sampling instructions can be randomly issued as needed to obtain the most authentic and effective water sample. It is one of the necessary instruments to improve work efficiency, reduce labor burden, and ensure the accuracy and effectiveness of monitoring data.
| Item | Index |
| Sampling method | Standard sampling: Sampling delay time: (1-9999 minutes) Any setting, in increments of 1 minute Sampling interval time: (1-9999 minutes) Any setting, in increments of 1 minute Sampling amount: (10-1000 mL) Any setting, in increments of 1 ml Mixed sampling: Sampling delay time: (1-9999 minutes) Any setting, in increments of 1 minute Sampling interval time: (1-9999 minutes) Any setting, in increments of 1 minute Sampling amount: (10-1000 mL) Any setting, in increments of 1 ml Number of mixed samples: (1-20) Parallel sampling: Sampling delay time: (1-9999 minutes) Any setting, in increments of 1 minute Sampling interval time: (1-9999 minutes) Any setting, in increments of 1 minute Sampling amount: (10-1000 mL) Any setting, in increments of 1 ml Number of parallel samples: (1-24) Flow triggered sampling: Special flow meter controls sampling. An ultrasonic liquid level sensor needs to be selected, with any setting from 1 to 9999 cubic meters of water, with an increase of 1 cubic meter Pulse trigger sampling: 1 to 9999 pulses can be set arbitrarily, with an increment of 1 pulse. The received pulse is a passive pulse with a closure time greater than 1 second |
| *Sampling pump characteristics | Sampling flow rate: 3700 mL/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, with a quick disassembly and assembly module combination. The motor shaft and pump tube roller bracket are made of stainless steel material Sampling error: ± 5% Sampling repetition accuracy: ± 5 mL Vertical lift: 8 m Horizontal suction lift: 50 m Pipeline system air tightness ≤ -0.085MPa |
| Software Functions | Operation interface: Large screen 2.8TFT color LCD display screen, all Chinese menus, human-machine dialogue mode, with Chinese prompts when human intervention is needed Split bottle sampling: The instrument can achieve 1-24 bottle split bottle sampling, and the number of bottles can be freely set. The distribution system is self-lubricating and self-locking in positioning, and adopts a direct water injection type to avoid cross contamination of water samples caused by the diversion plate. Pipeline cleaning: Use a "blow suction blow" method to clean the pipeline to avoid cross contamination of the sample Software password lock: can protect the program set in the instrument from being modified Sampling program preset: 10 commonly used working programs can be preset and stored according to sampling requirements, which can be directly called in the future External pump control: The sampling distance can be extended by controlling the external submersible pump or self priming pump Sampling records: sampling time, sampling status, and sampling bottle number. Can store 5000 pieces Flow recording: time, instantaneous flow, cumulative flow. Can store 6000 pieces (requires optional ultrasonic level sensor) |
| Other Parameters | 24 1000ml polyethylene water storage bottles for water storage containers Pre filtration: dedicated filter head. Stainless steel filter screens with corresponding mesh sizes can be selected based on water quality conditions System clock time control error △ 1 ≤ 0.05% and △ 12 ≤ 3S Mean time between failures (MTBF) ≥ 1440h/time Insulation impedance>20M Ω Refrigeration method: Compressor refrigeration: 4 ºC± 2 ºC digital display 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 channel passive Switching output 1 channel active, 15VDC/200mA |
| Conditions of Use | Power supply: AC 220V ± 10% 50Hz ± 1% Rated power: 160W Working environment temperature: -5 ºC to+50 ºC Working environment humidity: 5-85% RH Weight: 49kg Boundary dimension: W520mm × D579mm × H1047mm |
| Optional | 1.Optional smart cloud management platform for remote cloud platform control. (Sampling can be remotely set by any online computer or mobile phone) 2.Ultrasonic liquid level sensor (to achieve flow meter function) 3.Electronic access control: Normally closed with power off to prevent non staff from operating stored water samples |
