Multi-Parameter Soil Moisture Temperature Meter

The TZS Multi-parameter Soil Moisture Temperature Meter is a compact, portable handheld instrument designed for monitoring soil conditions in the field. Depending on the model selected, it measures soil moisture content, soil temperature, atmospheric temperature, atmospheric humidity, and dew point — giving researchers, agronomists, and environmental scientists a scalable toolkit that grows with their measurement needs.

The TZS family spans four models: the TZS-1K for soil moisture only, the TZS-2X adding soil temperature, the TZS-3X adding atmospheric temperature, and the TZS-5X extending further to atmospheric humidity and dew point. Each model saves data directly to the handheld unit and to a standard 4G Micro SD card, with storage capacity for up to 30,000 data groups. A power-off memory function ensures no data is lost if the unit loses power mid-deployment.

For unattended monitoring campaigns, the instrument supports both timed and manual data collection modes, logging readings automatically without requiring an operator on site. Up to 32 sensor channels can be read simultaneously via RS485 wired communication, with sensor cables reaching approximately 100 meters — suitable for distributed field plots, greenhouse arrays, or irrigation monitoring setups. The concentrator-based connection design maintains sensor accuracy when multiple sensors are combined.

Data can be reviewed directly on the LCD display or transferred to a PC via the Micro SD card. Low-power design, built-in battery charging protection, low-voltage alerts, and short-circuit/interference safeguards support reliable long-term deployment across soil science, crop research, ecological monitoring, and precision agriculture applications.
