LTF-II-CHandheld weather station with wind direction digital displayProduct Introduction

Handheld weather station is a portable and easy to operate mobile meteorological observation instrument that integrates multiple meteorological elements. The system adopts precision sensors and intelligent chips, which can accurately measure five meteorological elements including wind direction, wind speed, atmospheric pressure, temperature, and humidity simultaneously. Built-in large capacityFLASH storage chips can store meteorological data for at least one year; Universal USB communication interface, data can be downloaded to a computer using the matching USB cable, making it convenient for users to further process and analyze meteorological data. This instrument can be used in fields such as agriculture, forestry, environmental protection, oceanography, and scientific exploration.
