Obsolete Conductivity Cells

Our conventional contacting conductivity cells have changed very little since 1982. The J-boxes have changed from the nylon to ABS J-Boxes and then to plug on connectors for convenience of changing the cells without needing to disconnect the wiring. The dip cells have been manufactured with PVC, Kynar and Stainless steel riser tubes and the simple in line cells are still made in PVC.

Cells with 2 core screened cable red and blue have no Auto temperature compensator, cells with screened four core cable red, blue, green and yellow usually have an ATC.

To provide replacements we need to know the cell constant “K” factor and the auto temp compensator type and value. Listed below are some of the common cells we have supplied to work with our instruments.

D1 Series

D1 Series of dip cells made with K = 0.1. 1.0 or 10.0 Riser tubes in PVC, PVDF or Stainless steel.
With or without mounting flanges.
Available with fixed cables, J-boxes or plug on connectors.

D2 Series of dip cells made with K = 0.1 and 1.0 in PVC only still in production.

We can still supply many of these cells to replace the
originals.

IN1 Series

IN1 Series of cells in stainless steel for low conductivity water with K = 0.1 or 0.01. Also some lakewood 540 and 545 stainless steel cells where supplied manufactured in 3/4” dia stainless steel tube with a 3/4” compression fitting.

Replacement is our model PSE 01 with a K = 0.1 or PSE 001 with K = 0.01either cell can be supplied with ATC to suit the instrument in use.

IN2 Series

IN2 Series of cells made with K = 0.1, 1.0 or 10.0 Stainless steel boss with either 3/4” or 1” BSP male threads with either black nylon heads or ABS J-Boxes

We can still supply equivalents for many of these cells to replace the originals.

IN3 Series

IN3 series of PVC insertion cells with K =0.1 and 1.0 low cost cell for general use at ambient temperature.

Replacement is our model IN5 01 with K = 0.1 or IN510 with K = 10 fitted with mini plug on connector.

IN4 Series

IN4 HT Insertion cells with K =1.0 high temperature pressure cell in stainless steel for boiler blowdown use ,discontinued in the mid 1990s, now available again with disconnect connector (see current range of cells).

FL2 cell

FL2 cell for inline use, good qualilty cell moulded in epoxy with graphite electrodes, discontinued due to delivery problems and uncompetitive pricing.

Use CP721 cell which is manufactured in PEEK and graphite and either Stainless Steel or PVDF Tee for inline use.

Lakewood flow cell

Lakewood flow cell with quick release fitting, usually fitted to cooling water controllers but could have been used with other instruments. For use with 101 controller American spec ATC fitted. Cells assembled in the UK had ATC to suit local instruments. One of Dr Bob’s better designs.

Replacement use FL3 10 which can be fitted with any temp comp to suit the instrument in use.

If you do not see the replacement cell you require we may still be able to supply a replacement. Please email us a digital photo of your requirements stating the temperature, pressure and solution you wish to measure with details of the controller the cell is to be used with. Make model and measuring range required will also be of help in selecting a replacement cell for your application.
