1.Only when the temperature output option is V10 and A4,you need to choose the corresponding temperature volume18;otherwise,you can only choose 0.
2.The current type output adopts a long pole.
3.Example LFH513V10V102 represents the rod format,the temperature and humidity accuracy is±3%RH 20℃&60%RH
(±0.3℃ 20℃),and the humidity output is 010VDC.The temperature output is 0~10VDC,and the temperature volumeis20~60℃.
4.Prolonged exposure of the sensor probe to high concentrations of chemical gases may result in reading deviationsof the sensor.
