247W-L Weighted Conductivity and Temperature Probe


The 247W measured conductivity using three passivated 316 stainless steel annular electrodes with dc isolation capacitors. A thermistor measured water temperature. The 247W had an external, passivated stainless steel sleeve.

The "-L" on a product model indicates that the cable length is specified at the time of order.


Detailed Description

The 247W had a pH range of 3.0 to 9.0, with a conductivity accuracy of ±5% (at 25°C) over 0.45 to 7.0 mS/cm range, ±10% (at 25°C) over 0.005 to 0.45 mS/cm range. Operating temperature range was 0° to +50°C. Temperature polynomial linearization accuracy was typically less than ±0.1°C over 0° to +48°C range. Interchangeability accuracy was typically less than ±0.2°C over 0° to +50°C range.

The 247W-L (pn 8105) was replaced with the CS547, which was replaced with the CS547A.
