GNL-YF1 Oxygen Analyzer

* Specially used in wave soldering & reflow soldering oven to monitor the oxygen concentraton * 4-20mA or 0-5V DC signal output

1. Introduction                                                                                                 

New product GNL-YF1 analyzer (only for wave soldering oven and reflow soldering oven) breaks through traditional magneto mechanical measurement mode and measures oxygen concentration without benchmark gas by adopting conversion ion current with the world advanced technology as measurement principle. It has observable characteristics of long calibrating period, high precision, small appearance and low power consumption.

2. Features                                                                                                   

* New pattern, long-life, conversion ion current tester with fast response and high sensitivity

* Concise menu, simple operation

* Checking the sensor working state automatically and unique double-line working change mode extending the sensors life

* Setting upper and lower alarm values freely during the measure ranges

* 4-20mA or 0-5V DC signal outputs

* It can achieve two-way communication by connected to a computer via the standard RS232C or RS485 interface.
