LIQ-MAN-1066
Performance Specifications
Resolution:
0.001 ppm or 0.01 ppm – selectable
Input Range:
0nA – 100µA
Temperature compensation:
Automatic (via RTD) or manual (0-50 °C).
Input filter:
Time constant 1 - 999 sec, default 5 sec.
Response time:
6 seconds to 95% of final reading
Recommended Sensors
Rosemount 499ACL-03 Monochloramine sensor
Dissolved Oxygen (Codes –DO)
The 1066 is compatible with the 499ADO, 499ATrDO, Hx438, Gx438 and Bx438 dissolved oxygen
sensors and the 4000 percent oxygen gas sensor. The 1066 displays dissolved oxygen in ppm, mg/L,
ppb,
µg
/L, % saturation, % O
2
in gas, ppm O
2
in gas. The transmitter fully compensates oxygen read-
ings for changes in membrane permeability caused by temperature changes. Automatic air calibra-
tion, including salinity correction, is standard. The only required user entry is barometric pressure.
For more information on the use of amperometric oxygen sensors, refer to the product data sheets.
Performance Specifications
Resolution:
0.01 ppm; 0.1 ppb for 499A TrDO sensor (when O
2
<1.00 ppm); 0.1%
Input Range:
0nA – 100

Temperature Compensation:
Automatic (via RTD) or manual (0-50 °C).
Input filter:
Time constant 1 - 999 sec, default 5 sec.
Response time:
6 seconds to 95% of final reading
Recommended Sensors
Rosemount amperometric membrane and steam-sterilizable sensors listed above
Ozone (Codes –Oz)
The 1066 is compatible with the 499AOZ sensor. The 1066 fully compensates ozone readings for
changes in membrane permeability caused by temperature changes. For more information concern-
ing the use and operation of the amperometric ozone sensors, refer to the product data sheets.
