Brief introduction: ZK-FO creative type precision negative oxygen ion monitoring system USES the design of cylindrical electrode, enhances the electrodes on the surface of the conductive average sex and ion collection rate, at the same time, the intelligent control according to the constant velocity of airflow quickly by polarization electric field, which makes the burst type of negatively charged molecules to form electronic mass, greatly reduce its influence on the measurement, especially in long time measurement, inhibiting function will continue. This structure makes the ZK xsl-fo model precision of negative oxygen ion monitoring system measurement accuracy is greatly higher than that of traditional electric board type air negative ion detector, high sensitive cylinder collector on the air free ion collection rate is greatly increased, greatly overcome the similar product ion collection rate is not high, to detect the problem of numerical drift. Meet or exceed Japan "JISB9929" draft standard requirements. Features: 1. The sensor has high precision, fast and accurate test results, especially under the condition of low ion concentration can still achieve precise detection, 2. Completely in line with "gas ion density standard method of measurement" strict requirements 3. Compact structure, light weight, integrated temperature, humidity sensor and lithium battery, can adapt to a variety of outdoor conditions testing needs 4. The detection range (0 ~ 5000000 / cm3), can be horizontal or vertical detection and does not affect the test results 5. The built-in RS - 232, RS - 485 data port, with powerful dedicated software, easy to connect the computer to download records, analysis and printing 6. Super power-saving design, standby when can close the suction fan to save electricity Technical indicators: Measuring range: 0 ~ 5000000 / cubic centimeter Resolution: 10 / cm3 Accuracy: + / - 10% Power supply: 12 v The output format: RS485 Working temperature: - 20 ~ 50 ℃ Relative humidity: 0 ~ 100% Signal output signal output: 232, 232 signal output, 4-20 ma
