Professional Temperature & Humidity Monitoring
TSTH1-B sensor provides accurate readings for cold chain compliance
The TSTH1-B is a professional sensor specifically designed for temperature and humidity monitoring across wide-ranging applications. With high accuracy readings of ±0.2°C for temperature and ±2%RH for humidity, this sensor ensures your products are transported under strictly controlled conditions.
Ideal for transportation of temperature-sensitive products, the sensor provides critical data needed for maintaining cold chain integrity. The compact IP65 waterproof design ensures reliable performance even in demanding environments.
With EasiTrack's integration, you can monitor and control environmental conditions throughout your logistics chain, ensuring product integrity and regulatory compliance.

Long-lasting Battery Performance
Up to 8 years of battery life with flexible reporting options
The TSTH1-B sensor features remarkable battery longevity with a single replaceable CR2477 battery providing up to 8 years of service with 60-minute reporting intervals. This extended operational life minimizes maintenance needs and ensures continuous monitoring.
You can customize reporting frequency based on your specific requirements. More frequent reporting provides detailed data for critical applications, while extended intervals maximize battery life for long-term deployments.
Battery Life Based on Reporting Frequency:

Real-Time Alerts & Monitoring
Instant notifications for environmental condition violations
Set custom thresholds for both temperature and humidity to receive immediate alerts when conditions fall outside acceptable parameters. The system continuously monitors against your defined thresholds and sends notifications when violations occur.
With high-precision sensors (±0.2°C temperature accuracy and ±2%RH humidity accuracy), you can confidently monitor even the most sensitive products requiring strict environmental control.
Comprehensive monitoring capabilities:
- Temperature range: -40°C to +85°C (-40°F to 185°F)
- Humidity range: 10% to 90% RH with ±2%RH accuracy
- Customizable alert thresholds for different product requirements
- Multi-recipient alert configuration via email, SMS, or in-app notifications
- Historical data logging for compliance documentation and trend analysis

Transportation Applications
Our temperature & humidity sensors ensure product integrity across various transport scenarios

Fruit Transport
Maintain optimal freshness and extend shelf life with precise temperature and humidity control for various produce types that require different environmental conditions.
- Temperature range monitoring: 0°C to 15°C
