Instrument Introduction
Holder Electronics HED-111Aquaculture water quality measuring instrumentIt is a detection device suitable for industrial wastewater, aquaculture, river monitoring, swimming venues and other fields, combined with rapid colorimetric detection reagents,Aquaculture water quality measuring instrumentIt can measure quickly, simply, accurately, and stably, with a beautiful appearance, simple operation interface, and accurate detection system, helping users obtain fine data, analyze water conditions more accurately and effectively, prevent breeding risks in advance, and avoid losses in a timely manner.
Application Industry
Aquaculture water quality measuring instrumentSuitable for pure water plants, waterworks, domestic sewage treatment plants, industrial wastewater, aquaculture, river monitoring, swimming venues, water source protection, production monitoring, scientific research experiments, etc.
Detection Principle
Extract a certain amount of water sample, and after pre-treatment, drip the detection reagent according to the reagent instructions for different detection items. The detection reagent will react with the analyte in the water, and the reaction solution will present a specific color.
Instrument Features
Aquaculture water quality measuring instruments can detectPH、 Dissolved oxygen, ammonia nitrogen, nitrite, total alkalinity, hydrogen sulfide, salinity, phosphate, total hardness, water temperature, residual chlorine, detection indicators, etc.
Android intelligent system operation is more convenient and fast
Built in operation process, simple operation, no need for training, direct hands-on experience
Fast detection speed, on-site data reading
Portable, small in size, light in weight, convenient for outdoor testing
Compact and beautiful appearance, stable operation without maintenance, with good cost-effectiveness
Adopting imported cold light source, with stable optical performance and a lifespan of up to 100000 hours
