Envco – Environmental Equipment

The water quality analyzer can simultaneously measure: pH, temperature, dissolved oxygen, conductivity, salinity, turbidity, total dissolved solids (TDS), water depth, oxidation reduction potential (ORP), and seawater specific gravity. Featuring a powerful water quality analyzer and state-of-the-art functions, the water quality analyzer makes it easy to get highly reliable water quality data simply and quickly just by submersing the sensor in the water. The water quality monitoring system is flexible enough to use for checking the quality of a broad range of water samples, from factory effluent to urban drainage, river water, lake and marsh water, aquatic culture tanks, agricultral water supplies, and sea water. The main unit is water resistant, so it can be used safely even in the rain.

Up to one month Data logging (*with measurements every 15 minutes)!

The sensor's built-in memory function enables continuous measurement for as long as one month just by leaving the probe submerged in the sample. Personnel need not to be present during the measurement process the data can even be captured by personal computers in remote locations.

Measurement at depths as low as 100 meters
With its superior durability and high pressure resistance, the newly developed sensor facilitates measurements as far as 100 meters below the water surface. Thus, in addition to rivers, lakes and other shallow bodies, high-precision measurement can now be readily obtained and water quality can be monitored at dams, and even in the open sea.

Simultaneous measurement of 13 parameters
With the W-23XD unit (only), simultaneous measurements of up to 13 parameters (from pH, dissolved oxygen, and conductivity to seawater specific gravity and a variety of ions) can be obtained much more quickly and easily than with conventional instruments. With its powerful measurement capabilities, the compact U-20XD series is recommended for all water quality researchers and professionals.

System enables GPS and numerous other data processing mechanisms

System capabilities can be greatly increased by installing the Global Positioning System (GPS), supplied with unit U-2002. GPS allows measurement of location and time, in addition to water quality, and enables main unit screen display of the obtained data -an indispensable function for maintaining detailed records. With the acquired longitude, latitude and depth data, subject locations can be mapped in 3-D.
