CONDUCTIVITY
Portable Conductivity Meter Jenway,
Waterproof Premier range model 4200
A waterproof (to IP66 specification) portable Conductivity TDS meter
capable ot measuring 0-200mS over five automatically switched ranges
using a single cell. The 4200S software also enables results to be calculated
and reported as Total Dissolved Solids (TDS) in mg/l, Salinity in g/l or
Resistivity in Mohms.
The unique measuring cell is of configured 4-plate solid
state design guaranteeing linear response over a wide conductivity range
whilst minimising the effects of electrode fouling. Cell Constant values may
be entered directly if the value is known. Single and multipoint calibrations
may also be performed to ensure continued accuracy even when working
over extended ranges. All results are automatically temperature
compensated and may be referenced to any one of three temperature
values. Temperatures may be displayed in either °C or °F and temperature
coefficients between 0.00 and 9 99%/°C may be entered directly via the set
up menu.
A pure water mode is also available and enacts the non-linear temperature
cnefficient characteristics associated with low conductivity waters
The 4200 has the capacity to store up to 100 time and date stamped
readings in its non-volatile memory and these are retained even in the event
of battery failure or replacement Stored results may easily be recalled onto
the screen. Data may be transmitted to a PC or printer via a bi-directional
infra-red link using the opional Interface Cradle. An Interface Cable Kit is
also available to permi alternative cable configurations to the standard
25-pin D-Shell RS232. A self-contained 40-column printer is available as an
optional extra.
The unit is supplied complete with Conductivity cell K=1 and batteries

Laboratory Conductivity Meters Jenway models 4010/4020
A choice of two meters, one manual the other automatic, for routine
determinations of Conductivity.
The 4010 model is a low cost general purpose unit having five selectable
ranges each of which can be compensated to either 20C or 25C reference
temperature. A separate temperature probe also allows direct temperature
measurements from 30C to l50C. A zero control is provided for the
20uS/cm range to enable the elimination of effects from lead capacitance.
The 4020 model is a nicroprocessor controlled instrument with auto- ranging
from 0.01uS/cm to 1OOOmS/cm with slope adjustable automatic temperature
compensation. A display of temperature is shown on an auxiliary display
simultaneously with the conductivity reading. Further expansion of the range
can be effected by use of the optional X10 and X0.1 conductivity cells.
All data entry is via the membrane keypad and automatic monitonng of samples
can be calried out using the dual Hi/Lo alarm facility. An optional stand-alone
Clock/Printer module is available for this meter.
