The model 865 analyzer is designed and manufactured to give you fast response, flexibility, reliability, and ease of use. Automatic ranging reads directly in parts per billion (µg/L) without any need for manual setup. The analyzer's measuring range is from 0 ppb to 20 ppm D.O.
The intuitive user-friendly program “just seems to do what you expect.” The program has auto-calibration, self-diagnostics, fault tolerance, a 4-20 mA output for D.O. and a second one for D.O., temperature, or pressure. The analyzer has dual programmable alarms with self- and sensor diagnostic alert, and output hold during calibration.
Simple Air Calibration To calibrate, simply suspend the sensor over water, press the cal button, and let the analyzer auto-calibrate. Easy Operation Operators can easily change display to show ppb dissolved oxygen, barometric pressure, temperature, alarm setpoints, calibration status, etc. and make calibration adjustments. The program notifies of problems, and can be remote operated from your PC using the optional IC Net™ program. High Quality A stainless steel D.O. flowcell with double-shielded ppb dissolved oxygen sensor produces stable sub-ppb D.O. readings when sample is delivered via stainless steel tubing. Expert-Quality Calibrations At the low end, the sensor produces an accurate zero dissolved oxygen measurement. The problem of a drifting zero measurement is avoided because the sensor uses galvanic cell electrochemistry. When there is no oxygen present, there is no signal generated.
The sensor is calibrated in air which is saturated with water. The analyzer automatically compensates for temperature and barometric pressure when calculating the sensor gain. The operator does not need to use lookup tables or do manual calculations. Long-Term Stability and Easy Maintenance By design, cell chemistry regenerates and does not deplete the electrolyte. This produces long, stable runs between sensor recharges. Membrane replacement and sensor recharging is easy using a factory pre-tensioned pop-in module. IC Controls has incorporated intelligence into the microprocessor analyzers available via the IC Net Advanced Intelligence Access Program. Measurements such as DO can be critical to your process and must be strictly monitored and maintained. Analyzer Intelligence goes beyond measurement and control; it provides the user with historical data, including events such as calibration, upsets, diagnostics and more. This information can be communicated for trending or advanced control, even to remote locations. Ultimately, the user has superior control with a competitive advantage. The analyzer stores the last 12 monthly calibration records for communication or download and even keeps upset records! The last 20 upsets are recorded and datestamped (ie: out of spec, alarm, power interruptions, etc.) Factors leading to alarm conditions are recalled and for measurement trend hundreds of data points can be accessed at user defined time intervals. The optional IC Net Intelligence Access Program runs in your PC and communicates with one or more analyzers using RS485/RS232. The analyzer supports and communicates diagnostics. Settings can be viewed, functions tested, calibration updated and remote operated from your computer terminal. An optional Real-Time clock allows accurate tagging of events and duration even through power outages. Every IC Controls microprocessor analyzer incorporates intelligence that enables advanced process control and the ability to communicate with ease and flexibility - all in one analyzer!
