Reliable Performance for Temperature Monitoring

Wide Temperature Range & Durable Design

With 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.

Why TS201 Fits Pharmaceutical Temperature Monitoring?

Pharmaceutical Storage

Cold Chain

In pharmaceutical environments such as vaccine refrigerators, medical freezers, and drug storage cabinets, maintaining stable temperatures is essential for product safety. Frequent door openings or restocking can cause short-term air temperature fluctuations, leading to inaccurate readings and compliance risks.

TS201 is designed to ensure reliable storage monitoring with:

  • EN12830 compliance to support regulated pharmaceutical storage requirements
  • Optional glass bead thermal buffer bottle to simulate actual product temperature and reduce false readings
  • Local data storage & retransmission to ensure complete records for audits and traceability

This ensures accurate, stable monitoring and trustworthy data, helping maintain drug efficacy and simplify compliance management.

Transporting temperature-sensitive pharmaceuticals such as vaccines, biologics, and reagents requires strict, continuous temperature control throughout the entire journey. Any temperature excursion during transit may compromise product efficacy and compliance.

TS201 is designed to support reliable cold chain monitoring with:

  • Wide temperature range (-40 °C to 125 °C) to cover refrigerated and frozen transport conditions
  • LoRaWAN®-based connectivity for stable data transmission within facilities.

This enables end-to-end visibility and trusted data records, ensuring product integrity and compliance across the pharmaceutical cold chain

Advanced Features for Accurate Temperature Monitoring

Detachable Probe for Independent Calibration

TS201 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.

Learn More About Calibration Service >

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.

Real-time Alerts

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.

FUOTA Remote Upgrade Supported

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.

You May Want to Know

What is the difference between a TH probe and a DS18B20 probe?

The primary difference lies in their measurement capability and physical environment:

  • Measurement Scope: A TH probe measures both ambient Temperature and Relative Humidity, whereas a DS18B20 probe is a dedicated sensor for Temperature only.
  • Design & Waterproofing: TH probes require a vented or mesh cap to allow airflow for humidity sensing, making them unsuitable for submersion. In contrast, DS18B20 probes are typically encased in fully sealed, waterproof stainless steel, making them ideal for liquids and high-moisture environments.
  • Best Use Cases:

    TH Probes are best for monitoring air quality and climate conditions in places like greenhouses, grain silos, and warehouses. DS18B20 Probes are preferred for "contact" or immersion monitoring, such as tracking the temperature of milk in vats, water in pipes, or soil.

How does TS201 Temperature Monitoring Sensor help meet HACCP (Hazard Analysis and Critical Control Points) requirements?

TS201 supports HACCP compliance by enabling continuous and reliable temperature monitoring at critical control points such as storage units, refrigerators, and handling areas. It records accurate temperature data with local storage and retransmission to prevent data loss, ensuring a complete audit trail. Real-time alerts notify users of temperature deviations, allowing immediate corrective actions to protect product safety and quality.
