Environmental Monitoring

Family: WST Series
Category: Environmental Monitoring
Parameters: Wind speed and direction, temperature, humidity, pressure, noise, PM2.5/PM10 or CO2
Wind sensing: Mechanical, low moment of inertia

01Overview

Engineered for the field

A cost-effective weather station for short-term surveys or long-term environmental monitoring across multiple locations. Its integrated design combines a mechanical wind speed and direction assembly, balanced for a low moment of inertia and quick response, with sensors for temperature, humidity, atmospheric pressure, noise and either PM2.5 and PM10 or CO2. The small, lightweight body is made from UV-resistant material for a long service life, installs as a single unit, and reports over RS485 with a maximum consumption of 0.8 W.

02Key Features

What makes the WST-120 different

Cost-effective coverage

A low unit cost makes it practical to deploy stations across many locations.

Responsive wind sensing

Balanced wind speed and direction assemblies with a low moment of inertia react quickly to changing wind.

Air quality built in

Measures PM2.5 and PM10 together, or CO2, alongside the weather parameters.

Light and durable

Small, lightweight body made from UV-resistant material for a long outdoor service life.

Single-unit install

The integrated design means one device to mount and wire instead of separate sensors.
