CDH-287, $986, shown
with the CDE-5001-GDI
glass dip probe K=1.0
with ATC sensor, $156.
Portable Conductivity/Resistivity/TDS/Salinity Meter
The CDH-287 is a portable, multi-ranging
conductivity meter with unsurpassed
accuracy and reliability in the field. It also
measures resistivity, total dissolved solids
and practical salinity, making the CDH-287
the most versatile meter on the market. It
comes with a glass, dip-style conductivity
probe with an integral temperature sensor
and cell constant of 1.0. This microprocessorbased conductivity meter features autoranging, programmable temperature
coefficient and error diagnostics. Simply
pressing the keypad switches from
conductivity to TDS, resistivity or salinity
units. A concentration mode allows operators
to choose their own concentration units and
create a specific calibration curve, by
measuring up to four concentration standards
and inputting the values.
To increase range accuracy, cells are also
available with constants of K=0.1 and K=10.
Dip cells and flow cells are available in both
glass and epoxy body styles.
