ZTS Road Weather Station (Traffic Meteorological Station)
ZTS
The ZTS is a road weather information system (RWIS) that combines temperature, humidity, wind, rainfall, visibility and road-surface sensors into a single unit. It reports whether a road surface is dry, wet, covered in water, ice or snow, alongside standard weather parameters. The ZTS is available through MetSensor UK as the official UK supplier of professional environmental monitoring.
- ✓ Integrates the ZWS600 compact weather sensor, ZVS visibility sensor and ZRS road status sensor in one system

- ✓ Measures road/pavement temperature from -40°C to +70°C
- ✓ Visibility measurement range from 5m to 80km
- ✓ Operating temperature range -50°C to 85°C
- ✓ Data storage exceeding 5 years
- ✓ Optional GPS and 4G modules

Frequently asked questions
What does the ZTS road weather station report about road surface conditions?+
The ZTS reports the road surface as dry, wet, water, ice or snow, using its integrated ZRS road status sensor alongside a road/pavement temperature reading from -40°C to +70°C.
What is the visibility measurement range of the ZTS?+
The ZTS measures visibility from 5 metres to 80 kilometres with an accuracy of ±10%, using its integrated ZVS visibility sensor.
How does the ZTS communicate data?+
The ZTS supports RS485, RS232, WiFi and Bluetooth as standard, with optional LTE/4G and GPS for remote or mobile installations.
What is the operating temperature range of the ZTS?+
The ZTS operates from -50°C to 85°C, suiting installation on exposed road and bridge sites in the UK.
