  • 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.
