Product Name: Process Purity Oxygen Analyzer (SP-980L) Model NO.: SP-980L Trademark: CHANGAI Transport Package: Carton Specification: ISO9001; CE Origin: China HS Code: 90271000 Product Description SP-980L process purity oxygen analyzer is the online intelligent measurement instrument, which breaks through traditional magneto mechanical measurement mode and achieves to measure the oxygen concentration without benchmark gas by using solid electrolyte frequency conversion ion current oxygen sensor and oxygen pump. FeaturesNew pattern, long-life, conversion ion current tester with high sensitivity and fast responseHigh precision, automatic temperature compensation, eliminating the impact of environmental temperatureConcise menu, simple operationChecking the sensor working state automatically and unique double-line working change mode extending the sensor's life. Automatic data storage in a certain interval time, and browsing data at any timeBig screen DOT-matrix LCD, showing oxygen concentration, date and time synchronouslySetting upper and lower alarm values freely during the measure rangesIt can achieve two-way communication by connected to a computer via the standard RS232 or RS485 interface.
