1 Instrument Description: The nPTB-2024 water quality automatic sampler complies with the technical requirements and testing methods of the Chinese Ministry of Environmental Protection for water quality automatic samplers (HJ/T372). It is a multifunctional intelligent environmental monitoring instrument that integrates flow measurement, water sample collection, and automatic packaging. It has the characteristics of small size, easy mobility, simple operation, environmental protection and energy saving. Suitable for environmental monitoring stations, supervisory agencies, research institutes, water affairs, municipal and sewage treatment plants at all levels, automatic sampling of water samples from industrial pollution source discharge outlets, rivers, lakes, seas, etc.
2Main functional features
Multiple sampling program startup methods: preset time startup, external signal triggered startup, over limit sample retention startup, instant startup, liquid level over limit triggered startup, etc., to meet various user applications.
Multiple sampling functions: timed quantitative sampling, fixed flow quantitative sampling, flow ratio sampling, liquid level ratio sampling, real-time quantitative sampling.
Multiple external signal access methods, including4~20mASignal2roadRS232SignalRS485Signal and switch signal interface, convenient for online operation with online devices.
There is an automatic emptying function for the pipeline, which automatically empties the pipeline after sample collection to meet various water quality conditions. It also has a pre rinsing function for the pipeline to ensure the collection of representative samples.
Automatic sample packaging, with a variety of sample packaging methods.
Equipped with a remote communication interface, it can remotely control the startup through SMS and remotely check the on-site status (optional).
Rich operation record saving function, where every key operation of the user is recorded, facilitating future queries.
Rich data query function, large capacity data storage, can store10000Sampling records2000Alarm records can be queried for hourly, daily, and monthly traffic data for two years, facilitating user statistical analysis.
It has printing and communication functions, and can output on-site data to a computer or printer.
Two level password lock and two level management permissions to prevent illegal operations.
Liquid sensors detect liquids and improve sample collection accuracy.
Humanized program design, simple and efficient system operationThe sample volume of each sample bottle can be directly observed from the screen.
Using highly reliable peristaltic pumps and imported peristaltic tubes, with long service life, low noise, and low maintenance costs.
Built in large capacity lithium battery, dual-use for AC and DC, battery power can support continuous operation48Hours, equipped with a car charging interface.
The whole machine is small in size and light in weight, equipped with positioning universal wheels, making it easy to move.
The waterproof design of the whole machine ensures that it can work in rain and various harsh weather conditions, making it convenient for outdoor applications.
