Product Introduction
ACT-302 Digital Temperature Transmitter is a new product produced on the basis of the technical experience of independent research and development in the past. The instrument not only has the transmitter (4 ~ 20) mA analog signal output function, but also can increase the RS485 digital communication function. With the communication software, ACT-302 can be directly with the computer or other communication interface for data collection and the detecting data for storage, processing and report output; It adopts the most advanced micro power consumption devices and improved software technology; Further more , ACT-302 Digital Temperature Transmitter has the 5 digits LCD display with backlight that is very rare features in the Temperature Transmitter market.
