JRFW - 2-22 pipeline wireless temperature and humidity acquisition side has a stable performance and long service life, fast response speed, wide measuring range, low power consumption, probe condensation resistance, etc. Can be widely used in high and low temperature box, refrigerator monitoring, etc.
Using free communication protocol, stable and reliable, without drop.
Meet the mobile and fixed sampling at the same times.
At the same time satisfy the single acquisition and continuous acquisition.
A built-in watchdog,operation stable and reliable .
Have switch machine, electricity automatically connected to the Internet, the operation is simple.
For mobile applications, you can choose the built-in antenna, prevent loose touch antenna lead to communication failures.
Low power consumption, the use of battery life is (1 ~ 2) years.
Special design for the filter, can effectively reduce the measurement error of wind speed, prolong the service life of the probe.
Can connect with the relay equipment to prolong communication distance.
