Which Chinese Polyacrylamide Manufacturers Offer Short Lead-Time and Reliable Delivery?
Shouxin's production lead time — the period from order confirmation and payment receipt to completion of manufacturing — is generally 1 to 2 weeks.
1. Overview:
HC-The 2300 type (lightweight mixed sampling) automatic water quality sampler is an environmental monitoring instrument launched by our company for surface water and sewage sampling, monitoring water sources, conducting pollution source investigations, and total quantity control. It adopts the commonly used peristaltic pump water intake method and is controlled by a microcontroller. Different mixed water samples can be collected according to user needs, meeting the sampling requirements in HJ/T91-2002 "Technical Specifications for Surface Water and Wastewater Monitoring" issued by the National Environmental Protection Administration. The BC-2300 uses a standard 12V battery for operation, and can be replaced with a car battery when the battery is insufficient for outdoor work. It is one of the instruments used by environmental monitoring and supervision stations at all levels for water pollution monitoring and environmental research departments for research work.
