TS201 is a cost-effective sensor designed for pharmaceutical and food cold chain storage, enabling temperature and humidity monitoring from -40 °C to 125 °C, while ensuring compliance with EN12830 and supporting HACCP requirements for reliable, auditable data.
Reliable Performance for Temperature Monitorin
Wide Temperature Range & Durable DesignWith a temperature monitoring range from -40 °C to 125 °C, TS201 is well-suited for refrigerated storage and controlled environments. Its IP67-rated waterproof design ensures reliable performance across diverse deployment environments.
Compliance for Pharma & Food Monitoring
TS201 is certified to EN12830, ensuring it meets regulatory requirements for temperature monitoring devices used in food and pharmaceutical storage and transport. It also supports HACCP requirements by enabling continuous monitoring and reliable data logging, helping maintain product quality and simplify compliance processes.
Local Storage & Data Retransmission
TS201 stores up to 4000 records locally, preventing data loss during network interruptions. Once connectivity is restored, all buffered data is automatically retransmitted to maintain complete monitoring records.
LoRaWAN®-Based Low Power & Long Range
Leveraging LoRaWAN® technology, TS201 enables long-range wireless communication with low power consumption. It is ideal for scalable deployments with minimal maintenance requirements.
Advanced Features for Accurate Temperature Monitoring
Detachable Probe for Independent CalibrationTS201 features detachable sensing probes that can be calibrated independently. This ensures accurate temperature monitoring for sensitive applications. Calibration can be performed directly on the probe without removing the device, enabling faster recovery and minimizing downtime.
Pin-point Temperature Anomalies
Accurately spot temperature anomalies through receiving alerts sent from the sensing probe with its own identification number.
*The identification number helps to identify if the probe has been calibrated.
Users are able to receive immediate alerts for any potential threats, such as temperature spikes or opened doors. Data is swiftly transmitted to the cloud for easy access and retrieval, reducing inventory loss.
*It is advisable to place the device outside of the refrigerator.
TS201 supports Firmware Update Over-The-Air (FUOTA), enabling remote updates without physical access. This simplifies device management, reduces maintenance costs, and keeps systems up to date with the latest features and security enhancements.
