Overview
The 247 was similar to the 247W-L, except it did not have a stainless steel sleeve, and therefore had a smaller diameter. The 247W measured conductivity using three passivated 316 stainless steel annular electrodes with dc isolation capacitors. A thermistor measured temperature.
Technical Description
The 247 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. 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 247-L (pn 7343) was originally replaced with the CS547, which was replaced with the CS547A.
