9070 Sensor Unit
During calibration the 3,way valve is activated, a standard of known hydrazine concentration passesthrough a heat exchanger to equilibriate the solution's temperature to that of the sample. The standard then enters the constant head unit where flow is stabilized. Alkaline buffer vapor is added via a vapor entrainment mechanism before the standard enters the hydrazine cell and flows to drain. During normal operating conditions tile standard solution is replaced by the sample.

GENERAL SPECIFICATIONS

Performance



Range		0-100 ppb and 0-1000 ppb with automatic range change and two sets of normally open contacts, one of which closes for remote range indication.



Accuracy		± 5% of reading or ± 2 ppb, whichever is greater for concentrations up to 500 ppb. Less than 10% for concentrations above 500 ppb.



Stability		± 5% of reading or ± 2 ppb per week, whichever is greater.



Response Time		90% of a step change in less than 3 minutes.



Temperature Compensation		Automatic. Reduces sample temperature error to less than 0.5% of reading per degree C.
