Hydrazine Analyzer Series 2171 Specifications 70-82-03-64 November 2009 Introduction The 2171 is the most advanced hydrazine instrument specifically developed for use in continuous measurement and determination of hydrazine concentration in boiler feedwater. Common application points in a boiler system for online hydrazine measurement include: deaerator, condensate system and boiler feedwater. The 2171 hydrazine analyzer operates automatically and comes complete with true fully automatic calibration. Features Wide Analysis Range (0.01 PPB - 10 PPM) The fully automatic 1-point calibration Low maintenance : Autonomous nstrument for up to two months Grab sample capability No change of diffusion tubing Automatic Range Selection Process calibration-calibrate to sample Two 4-20mA isolated current outputs Protection of sensor from Hot sample Automatic temperature compensation Automatically stores last 10 calibrations and alarm logs Rechargeable hydrazine cell 2171 Sensor Unit The sample flows through the heat exchanger, passes through constant head (used to stabilize minor changes in flow rate) and through the three solenoid valves. A vapor entrainment mechanism adds alkaline buffer vapor to the sample before it enters the sodium measuring flow cell and flows to drain. Calibration and grab sample are controller automatically by the analyzer. Standard/grab sample liquid is brought into system via the three 3-way solenoid valves. A thermistor is housed in the flowcell and is used to detect the temperature of the sample/standard/ grab sample.

Hydrazine Analyzer Series 2171C Specifications 70-82-03-65 September 2009 Introduction The 2171C is the most advanced hydrazine instrument specifically developed for use in continuous measurement and determination of hydrazine concentration in boiler feedwater. Features Wide Analysis Range (0.01 PPB - 10 PPM) Low maintenance Very low reagent and standard consumption to be changed only every two months Self diagnostics Stable ph through vapor buffering No change of diffusion tubing Automatic Range Selection Process calibration-calibrate to sample Two 4-20mA isolated current outputs 3 relay contacts for high, low and general alarm Large, easy-to-read 128 x 64 pixel graphic LCD display Internal diagnostics to show probe status Protection of electrodes from Hot sample Communication interface via RS-232 & RS-485 using MODBUS RTU protocol User-configurable settings for recorder outputs and alarm set points Automatically stores last 10 calibrations and alarm logs Hydrazine Analyzer 2171C Sensor Unit During calibration the 3-way valve is activated, a standard of known hydrazine concentration passes through a heat exchanger to equilibrate 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 the standard solution is replaced by the sample. Wide range of input power supply: 90VAC 250VAC Rechargeable hydrazine cell Sensor Parts
