Reminders when choose models
1. Pay attention to media which is measured is compatible with part of product
2. Anti-exposion products don't have LCD or LED dial
3. Order temperature transmitter with LCD or LED dial, the power voltage shouldn't be less than 20VDC
4. In order to keep stable performance, we suggest user to install lightning protection device
5. If there is strong vibration, strong electromagnetic, RFI, please state before order and indicate in order.
