The Dissolved Oxygen Analyzer should be installed where the following conditions can be maintained:
Sample Flow 100 to 300 ml/min.		Sample Temperature 41 - 131° F (5 - 55° C)
Ambient Temperature 32 - 131° F (0 - 55° C)		Pressure 5 - 100 psig
Composition Filter to 60 micron, free of film forming compounds

Range:
0-20 ppb, 0-200 ppb, 0-2 ppm and 0-20 ppm with automatic range change and four sets of normally open contacts, one of which closes for remote range indication.

Accuracy:
=1 ppb of reading.

Precision:
±.5 ppb of reading.

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

Calibration:
Automatic on-line every 7 days or manually initiated when required.

Alarms:
Two voltage-free contacts. Alarm points set from transmitter rated at 250V tamp, noninductive.

Dimensions:
Electronic Transmitter - 1 1.87" W x 1 1.87" H x 8" D Liquid Handling System - 12.13" w x 16" H x 8" D Can be separated 325 feet apart.

Weight:
50lbs.

Current Outputs:
Two isolated outputs - switch selectable, 0-10 mA, 0-20 mA or 4-20 mAdc, 100 ohms.

Response Time:
90% of a step change in 60 seconds.

Atmospheric Pressure Compensation:
Programmable; preset to normal atmospheric pressure at geographical site location.

Thermal Protection:
Automatic sample bypass if sample exceeds 131 ° F (55° C).

Power:
120/240VAC (+10%-20%) 50/60 Hz.

Degree of Protection:
Two steel cases; flow thru sample cabinet, all wetted parts stainless steel or plastic. Finish is corrosion resistant Polyurethane. NEMA 4X.

The autocalibration is achieved by draining the flow cell and exposing the probe to air. This is carried out automatically on-line for three minutes and involves no manual operation. An automatic calibration check is performed every 7 days. Calibration can be initiated at any time manually by depressing the Manual Calibration Pushbutton on the instrument panel.

The Liquid Handling System features an air-tight flow cell housing a disposable solid state no maintenance DO sensor. The flow cell is self cleaning, preventing air bubble entrapment and minimizing particle deposition. The sensor is a galvanic membrane covered three electrode electrochemical cell. The sensor can be easily unscrewed from its holder, discarded, and replaced, an operation taking less than 60 sec. to perform.
