Quality Control Method | Long Term DO Measurement
Establishing quality control data for dissolved oxygen monitoring projects is essential for verifying the accuracy of the data. The world's smallest, easiest-to-use, and most affordable temperature measurement and data logging system! The Vaisala WXT510 measures the six most essential weather parameters all in one compact, lightweight instrument. NexSens WQSensors: Changing the face of the water quality sensor market. They fill a much-needed gap in the water quality industry. The YSI 556 with flow cell is a perfect tool for low flow sampling. It's compact, easy-to-use and simplifies field sampling. With iChart software, your computer becomes a control center for monitoring water quality, flood detection, weather, river discharge, and much more. The Hach 2100P Turbidimeter meets this demand by providing a portable, field instrument with lab quality results that meets or exceeds USEPA requirements. Ensure the distribution of safe drinking water to your community with YSI Drinking Water Multiprobes - the industry's first affordable, portable, multi-parameter system to collect continuous data on a distribution system. To meet the demand for low-cost, accurate, real-time weather monitoring, NexSens has introduced weatherPACK, an easy-to-use system that requires minimal assembly and no programming. Ideal for continuous flow monitoring in small channels from 1 to 16 ft deep, the Argonaut-SW (shallow water) offers advanced Doppler performance for sites previously thought impossible to measure. The Stingray Remotely Operated Vehicle is Benthos' solution to the ever-changing needs of inspection class ROVs. The RiverSurveyor ADP collects vertical profiles of water-velocity, water depth, and vessel-velocity and sequentially calculates discharge in vertical increments from one bank of a river to the other. The YSI 600 LS provides an accurate and economical system for in-situ, long-term monitoring of temperature, conductivity, salinity, water level, and discharge. Profiling systems from YSI provide a means of measuring water quality parameters throughout a vertical column. They are available in three configurations: fixed profiler, pontoon profilers, and a buoy profiler for coastal applications. SonTek's exclusive ADV technology has not only simplified traditional flow measurements, but it has taken the FlowTracker into applications previously unthinkable with conventional current meters. Hach/Sigma 900 Series samplers can improve the efficiency of virtually any water sampling program. The Datasonics CAP-6600 Chirp II Sub Bottom Profiling System by Benthos utilizes advanced Chirp technology to acquire, display, and record high-resolution profiles of both the near-bottom and deeper sub-bottom layers. In response to customer requests for an instrument that could withstand harsh conditions for weeks at a time, YSI developed the 6600 EDS sonde. The new 500-kHz Argonaut-SL offers extended range and a vertical beam for continuous large river discharge measurements. iChart is an advanced data acquisition software package designed for environmental monitoring applications. The C3D is manufactured to the highest quality and reliability that one should expect in the offshore environment. Until the advent of in situ Rhodamine WT measurement systems, dye fluorometry hydrologic measurements were performed by the analysis of multiple samples physically extracted from the water body as the dye plume was naturally dispersed. NexSens - one of the fastest growing environmental equipment suppliers, has recently introduced two new products, the ts110 and WQData. OTT Hydrometry is enhancing its reputation as maker of the world's most reliable, versatile, and durable precipitation gauge, the Pluvio. The next generation YSI ROX is a luminescent-based DO sensor that offers YSI customers long-term oxygen measurements in severe fouling and low oxygen environments. Blue-green algae are of interest for ecosystem studies and monitoring as well, where they may represent the most abundant primary producer.
