Introduction:
The AST900 is a high-performance lower wireless communication temperature gauge which is based on our high accuracy temperature transmitter platform and combined with low power consumption technology, high reliability of RF communication modules and high-capacity Li-ion battery. PC can read the transmitter' s real-time temperature data by the ASC400X data collection terminal which has two kinds of communication interface: USB and MODBUS
The AST900 can work normally without external power supply so that no separate cable needs to be run to the field
The instrument is especially suitable for no power supply condition and transmission of real-time data, such as oil fields, metallurgy and other areas
