P860 oxygen nitrogen analyzer

Nitrogen analyzer (21%-99.999%) / Oxygen analyzer (1%-21%) p950 (10%-96%) This instrument adopts the principle of oxygen measurement. When the oxygen sensor converts the oxygen concentration in the gas into an electrical signal, it is calculated by a subtractor to calculate the nitrogen content. And directly display the nitrogen percentage content in the measured gas. The instrument is manufactured with advanced medium and large-scale integrated circuits and 4.5-digit LED high-brightness digital display. The instrument has a digital dial to set the lower limit control. It is convenient and fast. When the nitrogen content of the monitored system is lower than the set value, the control contact Start. And there is sound/light alarm at the same time. The instrument also has 4-20MA synchronous signal output. And has functions such as automatic zero stabilization, the instrument can directly display 1/10, 000 reading. (99.99%) Fast response, high precision, stability and reliability, easy to operate and so on. This instrument can be calibrated by using the nitrogen content of the air at 79.0%, which is easy to operate and has an automatic range conversion circuit. When the nitrogen concentration is greater than 90.3%, the instrument range is automatically converted and the reading is 90.30%. The instrument is equipped with a digital dial single lower limit control setting circuit, the setting range is 91.00% ~ 99.99%, 1. KY-2N When the nitrogen concentration is lower than the set value of No. 1 lower limit (if it is 99.96%), the alarm indicator light is on, and there is an alarm sound. The alarm output switch is activated (The corresponding control equipment can be activated according to needs). The instrument has 4～20mA signal output which can be connected with the recorder. This instrument is suitable for pressure swing adsorption nitrogen generators, air separation equipment, and nitrogen concentration analysis, monitoring and control in nitrogen-oxygen mixtures Technical indicators 1.
