Seawater Dechlorination Analyzer
Seawater Dechlorination Analyzer
The Model DCA-23 Seawater Dechlorination Analyzer from Electro-Chemical Devices (ECD) is a low maintenance measurement solution that requires no chemicals to monitor seawater chlorine levels accurately in a wide range of industrial process and municipal water treatment applications.
Seawater has multiple process industry uses, including heat exchange systems at LNG terminals, oil/gas refineries, electric power plants and SWAC systems (salt water air conditioning) in commercial buildings. The DCA-23 is a single-purpose analyzer that monitors chlorine in seawater from 0.0 to 2.00 ppm. It features an economical, low-maintenance design that requires no chemicals.
The analyzer measures the pH, temperature, and Total Residual Oxidant (TRO) of seawater and converts them into an equivalent ppm chlorine value, which is displayed to conform with existing conventions. It features a minimum detection limit (MDL) of 0.014 ppm and a limit of quantification (LOQ) of 0.044 ppm, making the DCA-23 Analyzer suitable for monitoring in environments with the most stringent dechlorination regulations.
The DCA-23 features three sensors, pH, TRO and temperature. The pH sensor measures from 0-14 pH, the TRO sensor measures from ±1500 mV and the temperature sensor measures from 0-100°C. The DCA-23 with its tri-parameter monitoring, is the ideal seawater chlorine analyzer for a wide range of applications.

Traceable Digital Thermometer
Control Company's Traceable Digital Hygrometer/Thermometer/Dew Point instrument provides a response time of under 10 seconds with a resolution of 0.01% RH, 0.01°F/°C, and 0.01° dew point °F/°C. It samples one-and-a-half times per second. Results are reported in both °F and °C from –40.00 to 220.0°F (–40.00 to 104.0°C) temperature, and from –40.00 to 140.0°F (–40.00 to 60.00°C) dew point. Temperature resolution is 0.01° with an accuracy of ±0.4°C. High and low alarms can be programmed in dew point/frost point, temperature, and humidity. When an out-of-range condition is sensed, an alarm sounds and the display flashes. Computer output permits data to be captured, transferred, stored, and printed. Memory recalls both minimum and maximum readings in dew point/frost point, temperature, and humidity at any time.
Fluid Imaging Technologies
Fluid Imaging Technologies' FlowCAM PV Series imaging particle analysis system features two new analyzers, the FlowCAM PV-5x and FlowCAM PV-10x, that are pre-configured to promote maximum speed, efficiency, accuracy and repeatability in laboratories where analyses are performed on products and/or on particles. The analyzers can detect thousands of particles and microorganisms, in a sample, in less than a minute, and take a hi-resolution, full color digital image of each one detected while measuring them based on the actual size and shape of the images and characterizing them with up to 32 different parameters - all in real-time.

The AND1000 Fluorimeter enables field testing in two short steps, eliminating or significantly reducing test expenditures, complexity and wait times experienced in traditional heavy metal water testing. ANDalyze's proprietary catalytic DNA sensors use a DNAzyme reaction that fluoresces in the presence of a target contaminant substance such as lead, uranium, copper and mercury. The fluorescence of the reaction is dynamically measured to determine the concentration of the target heavy metal at levels in the low parts per billion (ppb).
