Note:
1. Only when the output option is V10, A0, or A4, the temperature range 1-8 must be selected,otherwise,only0 can be selected.
2. Example LFH75-A42202 represents an embedded temperature and humidity transmitter with current output 4-20mA, temperature range -20-60℃, stainless steel sintered filter, and 2-meter cable length.
3. Prolonged exposure of the sensor probe to high temperature and humidity environments may cause humidity drift, which can be restored by placing it in a normal environment.
