Sampling Pump
The analyzer uses a peristaltic pump for sampling. Pump tubing must have the proper
diameter suitable for the pump. The diameter and the material of the tubing is very important;
use only Waltron spare parts.
3 Way Valve
Allows the analyzer to choose between Sample Inlet 1, Sample Inlet 2 (dual stream units
only), and Calibration Standard Inlet for analysis.
Sample Inlet
The tubing for the sample inlet(s) and calibration standard inlet pass through the housing
enclosure on the right hand side of the unit and are connected to the 3 way valve.
Colorimetric Reaction Cell
The colorimetric reaction cell is made of glass; the diameter is 16 or 25 mm, depending on
the parameter. The cell is positioned inside a thermostated block fixed with 2 screws. The
block can be easily removed to allow the cleaning of the glass cell.
Reagent Pumps
The reagents are dosed with peristaltic pumps. The 3041 has three reagent pumps.
Pinch Valve
Normally-closed pinch valve to pinch or open the drain tubing in order to close or open the
