Water Quality Sonde Product Description
The W-23XD
water quality sonde brings laboratory accuracy and the ease of
push-button operation to water quality instrumentation
measurement in the field. Years of water quality
instrumentation technology development have resulted in the form
of a 97-mm diameter water quality sonde: a compact water quality
instrument able to offer high pressure tolerance, long-term
continuous measurement capability and highly accurate for the
simultaneous monitoring of up to 13 parameters. The water
quality sonde can simultaneously measure: pH, temperature,
dissolved oxygen, conductivity, salinity, turbidity, total
dissolved solids (TDS), water depth, oxidation reduction
potential (ORP), seawater specific gravity and up to three
specific ions. Featuring a powerful water quality sonde and
state-of-the-art functions, the water quality instrumentation
makes it easy to get highly reliable water quality data simply
and quickly just by submersing the sensor in the water. The
water quality sonde 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, agricultural water supplies, and seawater. The
water quality instrumentation is water resistant, so it can be
used safely even in the rain.
Measure Up to 13 Parameters
The W-23XD water quality instrumentation can simultaneous
measure 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 the water quality
instrumentation's powerful measurement capabilities, the compact
W-23XD water quality sonde is recommended for all water quality
researchers and professionals.
Automatic Water Quality Sonde Calibration
The W-23XD water quality sondes have an automatic calibration
function that calibrates the instrumentation simply at the touch
of a button for more highly reliable data. What used to be a
complicated calibration process is now easy. Just fill the
supplied beaker with the standard solution, immerse the water
quality sonde and press a button once for one-point calibration
for each of the five main parameters pH, conductivity,
turbidity, DO, and depth. One point calibration is also
available for three ion parameters, Cl-, NO3-,
and Ca2+. Two-point calibration is also possible
where high precision measurement data is required.
Deep Water Quality Measurments
With its superior durability and high pressure resistance, the
water quality sondes facilitate measurements as far as 100
meters below the water surface. Thus, in addition to rivers,
lakes and other shallow bodies, high-precision water quality
measurements can now be readily obtained and monitored by the
water quality instrumentation at dams, and even in the open sea.
Built in Data Logger
The W-23XD water quality sonde's built-in memory function
enables continuous measurement for as long as one month, just by
leaving the sonde submerged in the sample. Personnel do not
need to be present during the measurement process, the data can
even be captured by personal computers in remote locations.
NOTE: Must purchase U-PCDLP to export data to a computer.
