Physical characteristics Specifications
Linear range 0 to 20 ppm (mg/L) as Cl
2
(for higher ranges,
consult factory)
Linearity (per ISO 15839) 0 to 10 ppm: 2%; 0 to 20 ppm: 3%
Response time Following a step change in concentration, the
reading reaches 90% of final value within 7 mi-
nutes at 25 °C (77 °F)
Drift At about 1.5 ppm in clean water and constant
temperature, drift is typically less than 0.05
ppm over two weeks.
Detection limit (per ISO 15839) 0.02 ppm (mg/L) in clean water at room tem-
perature

Rosemount TCL Reagent-Based Chlorine System
The TCL is used for the continuous determination of total chlorine in water. The TCL
consists of a sample conditioning system, a reagent carboy, a sensor, and a transmitter.
Important
Reagent kits must be ordered separately. Reagent kits for 0-5 ppm and 0-10 ppm chlorine are
available. For higher ranges, consult the factory.
See Table 1-5.
