Two cell factors are offered, 0.1 cm-1 and 10 cm-1.
The 0.1 cm-1 types are used for resistivity measurements and any conductivity measurements below 200 uS/cm. They are offered with either titanium or monel electrode materials.
The 10 cm-1 types are used for higher conductivity measurements above 200 uS/cm, and employ graphite electrodes covered with a removable metal sheath. For pure and ultrapure water measurements, the 871CR sensors provide the highest possible accuracy.
Each 0.1 cm-1 sensor is individually characterized and labeled with a 0.1% accurate cell factor value. The built-in temperature sensor is a high accuracy, 3-wire, 1000 ohm platinum RTD.
The threaded bushing material is plastic to resist temperature offsets caused by swings in ambient temperature. Several mounting styles are available, including threaded bushing (3/4 inch and 1 inch NPT), Tri-clamp sanitary, universal with O-ring seal and retractable with a ball valve or gate valve assembly. The universal bore piece mounting design prevents cable wind-up during installation and removal.
Several mounting accessories are also offered, including flow chambers, threaded bushings and flanges.
For optimized sampling, the 871CR sensors are provided in several different insertion lengths.
