LSI LASTEM ToTEM
Professional environmental monitoring in a compact design
LSI LASTEM ToTEM, is a compact station family measuring ultrasonic wind speed and direction, temperature, relative humidity and atmospheric pressure in a single housing. The manufacturer states measurement accuracies in accordance with WMO requirements.
Depending on the model, it provides precipitation, Class A / B / C solar irradiance, black globe temperature and PM measurements. It can be used in meteorological observation, energy sites and occupational safety applications.
- Integrated sensor architecture for core meteorological parameters.
- Monitoring of precipitation, solar irradiance, WBGT (wet bulb globe temperature) / UTCI (universal thermal climate index) and PM1 / PM2.5 / PM10 depending on the model.
- Serial output or LTE-M eSIM / LoRa communication options; ENVIRO CUBE integration.
- Smart heating and ventilation, replaceable measurement head and USB-C configuration.
Model and Communication Options
Measurement package and communication option depend on the model. The manufacturer's scheduled availability is April 2027 for LTE-M () models and June 2027 for LoRa () models. These options are currently planned products. Detailed specifications are given in the Technical Brochure.
Data Transmission and ENVIRO CUBE
Serial-output ToTEM models can be connected to data acquisition systems. LTE-M eSIM or LoRa options provide remote transmission via suitable infrastructure. ENVIRO CUBE supports cloud-based data monitoring and analysis.
Maintenance and Measurement Reliability
Smart heating and ventilation support continuous outdoor measurement. The temperature / humidity / pressure head as well as Class A and B irradiance sensors are field-replaceable. ISO/IEC 17025 calibration certificates can be requested for parameters within the accredited scope of the LSI LASTEM laboratory.
Application Areas
Solar irradiance measurement in solar power plants; thermal stress assessments on construction sites using models with black globe sensors. Meteorological conditions can be monitored along highways, coastal areas and in urban locations.
Frequently Asked Questions
Which parameters does ToTEM measure?
Base models measure wind speed and direction, temperature, relative humidity and atmospheric pressure. Precipitation, irradiance, black globe temperature and PM measurements depend on the model.
Can solar irradiance and thermal stress measurements be performed?
Applicable models feature an ISO 9060:2018 Class A, B or C pyranometer. Models equipped with a black globe sensor support WBGT and UTCI calculations.
Can data be monitored remotely?
Data can be transmitted via LTE-M eSIM or LoRa with the appropriate communication and service configuration. ENVIRO CUBE integration supports cloud monitoring. The manufacturer indicates a schedule of April 2027 for LTE-M () models and June 2027 for LoRa () models; current availability dates should be confirmed separately.
How is the right configuration determined for my application?
You can share the parameters to be measured, the installation environment and your data transmission requirements with NOVEL. The appropriate sensor and communication package will be determined based on this information.
