Temperature and humidity sensor

The temperature and humidity probe is to use with the ACCUSENSOR measurement systems. It is equipped with a cable with a RS485 plug fitting to these devices. As temperature sensor a precise NTC is used. Furthermore, the humidity measurement works with a long-term-stability capacitive polymer sensor. The current measured values are transmitted by the USB or RS232 interface to the connected PC. The recording and graphic evaluation is made on the PC. The MODBUS protocol of data communication is documented and allows integration into own softwares. The measuring probe is delivered calibrated. As accessories, reference cells are available. Therefore the accuracy of the probe can be checked by the user.
