产品名称：Series 2000 Percent Oxygen Analyzer

System Description
The Series 2000 Percent Oxygen Analyzer is a microprocessor-controlled instrument that can be supplied with oxygen measuring ranges from 0-0.5% to 0-100%. Single and three range instruments are available. Autoranging is a standard feature on all three range analyzers. The Series 2000 Percent Oxygen Analyzer is powered from 115/230 VAC, 50-60Hz, or 18- 32 VDC with optional battery backup available for certain models. Oxygen values are displayed continuously on an easy-to read, 0.4" (10.2 mm) high, 4-1/2 digit liquid crystal display (LCD). The instrument can be purchased in a variety of mechanical configurations ranging from a general purpose, portable device, to a NEMA 7 (explosion proof) system. The electronics enclosure used for the portable and panel mounted versions is made from durable polycarbonate and, together with the gasketed seals, is rated watertight NEMA 4X (IP66). The gas inlet and outlet connections on the sensor housing are quick connect types. One-quarter inch stainless steel compression fittings are available upon request.

The Series 2000 Percent Oxygen Analyzer features a patented, extended life oxygen sensor with EES (enhanced electrolyte  system) . This sensor provides exceptional performance,accuracy, and stability. For applications where carbon dioxide is present in the sample gas, the EES retards passivation of the sensor anode by allowing the products of oxidation to dissolve in the electrolyte. In effect, the sensor is renewed continuously, resulting in an increase in sensor life even if exposed to limited amounts of carbon dioxide. In addition, the enhanced mechanical design of the sensor ensures longer life, and virtually eliminates leakage of electrolyte, a nagging (and expensive) problem associated with sensors that require periodic electrolyte maintenance.

The eloquence of the Series 2000 Percent Oxygen Analyzer is its ease of use. The front panel contains five switches that provide access to the instrument’s settings. Each analyzer is equipped with three oxygen alarm relays and one status alarm relay as standard equipment. All four relays are Form C (SPDT) types rated at 10 amps at 115/230 VAC and 30 VDC. Each relay is user configurable for fail-safe operation. In addition to the alarm relays, the analyzer is equipped with a built-in audible alarm, as well as three front panel  LEDs for visual indication of an alarm condition.

The Series 2000 Percent Oxygen Analyzer comes equipped with two analog outputs, 4-20 mADC and 0-2 VDC, for use with recorders, dataloggers, etc. For enhanced communications, the Series 2000 Percent Oxygen Analyzer can be configured with optional RS-232C or RS-485 serial communications. For multiple point installations, the RS-485 format is capable of sending digital signals over greater distances, and controlling each monitor using the same communication channel.
