JRFW-2-21 900M Temperature And Humidity Acquisition End

The product model:JRFW-2-21
Manufacturers:Collihigh
The production:China
Attention index:3761
Introduction

JRFW-2-21 900M temperature and humidity acquisition end using imported high-precision probe and sensing special analog integrated circuit,it has reliable performance and long service life, fast response, wide measuring range.It has low price and high precision in similar products.

This product uses its own protocol, with ultra-low power consumption, good stability, simply for use, free of parameter configuration. By matching with the relay equipment can effectively extend the communication distance. It can widely used in cold chain transportation,  indoor temperature, temperature and humidity, intelligent building, subway, mall, library and other places.


Use

It can widely used in cold chain transportation, communication room, indoor temperature and humidity, intelligent building, subway, mall, library and other places.


Characteristic

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.
