Product Details
Product Overview:
The DR-801C water quality petroleum sample sampler is a specialized collection tool for oil sample analysis, which meets the requirement of "Water and Wastewater Monitoring and Analysis Methods" (Fourth Edition Supplementary Edition) that oil sample collection in water cannot be transferred twice.
The DR-801C water quality petroleum sample sampler is a fully automatic and portable sampler that has obtained national patents. The sampling container has excellent sealing performance and can be directly sent to the laboratory for adding extractants and using an oscillator for oscillation extraction.
The DR-801C water quality petroleum sample sampler can collect representative oil samples in water, which is a key technology in the entire oil project analysis process, improving the representativeness and reliability of oil monitoring data and filling the gap at home and abroad.
Application fields:
The DR-801C water quality petroleum sample sampler can be widely used for industrial wastewater, oil fields, domestic sewage, surface water, marine environmental monitoring, etc.
Principle and functional characteristics:
Principle: The static truncation sampling method can fully collect a section of water column containing surface oil and subsurface oil, making the water sample represent 95% of the oil content and more representative;
The container is made of glass or stainless steel material, which is not dissolved by extraction reagents and has high compressive strength;
The container has locking devices at both ends;
The container can be directly entered into the laboratory, added with extraction reagents, and placed on an oscillator;
The sampling system is made of stainless steel material, with high strength, no rust, and can be used in various application environments;
Powered by batteries, replaceable and rechargeable.
