Myron L Aquaswitch II - Manual (Page 9)

E . S E N S O R S
All sensors feature integral thermistor style temperature sensors
to ensure accurate, rapid and reliable automatic temperature
compensation.
1. CONDUCTIVITY/TDS
AQUASWITCH II Conductivity/TDS Monitor/controllers use the
CS51LC or CS51 Series sensor depending on range. The 1.0 cell
constant CS51 model is recommended for ranges of 0-10 through
100 µS/ppm. Its compact size allows mounting in a standard 3/4"
tee. The sturdy polypropylene bushing is modular for easy,
inexpensive replacement. Other models available by special
order.
CS51LC sensor has a cell constant of 0.1 and is used for
conductivity/TDS values of 0-1 to 0-5 µS/ppm.
2 . R E S I S T I V I T Y
AQUASWITCH II Resistivity Monitor/controllers use the CS10
sensor. It has a cell constant of 0.05 and is used for ultra pure
water applications. Other models available by special order.
Special order High Temperature, High Pressure sensors; and Low
Cost, Low Temperature, Low Pressure sensors are available.
For detailed descriptions of these and other sensors, see Sensor
Selection Guide and specific sensor data sheets available from
your local distributor, the Myron L Company, or on line at
www.myronl.com.
