Question
What is the purpose of the sample heater in the 5500/961X Silica/phosphate analyzer?
Summary
5500/961X Silica/phosphate sample heater. 
Answer
With the 5500/961X Silica/phosphate analyzers, heating the sample will facilitate the chemical reaction to ensure a fast response time and because the temperature is constant it can ensure accurate results.
The system will heat the sample and the colorimeter to 50° C regardless the incoming sample temperature. If the sample heater is not functioning properly, the analyzer will give a ‘temp out of range’ error. 
The heater can be tested using the instructions here:  How test the sample heater on a Series 5500 Silica or Phosphate (120 VAC Models Only).
The heater fuse can be reset with the instructions here: Is it possible to reset the sample heater fuse on the 5500 sc Phosphate and Silica analyzers?
