testo 150 T1 Temperature Data Logger Module with Integrated NTC Sensor (Model 0572 3350)

Overview

The testo 150 T1 Temperature Data Logger Module (Model 0572 3350) is a DIN EN 12830:2018-certified, battery-powered environmental monitoring device engineered for continuous, traceable temperature measurement in regulated pharmaceutical, biotech, and clinical storage environments. As a core component of the testo Saveris Pharma monitoring ecosystem, the T1 module employs a high-stability integrated NTC (Negative Temperature Coefficient) thermistor to deliver reliable, repeatable temperature readings across standard ambient and refrigerated operating ranges. Its measurement principle relies on precise resistance-to-temperature conversion calibrated per IEC 60751 and traceable to national standards. Designed for deployment in cold rooms, stability chambers, vaccine refrigerators, and transport validation scenarios, the module operates autonomously—recording data at user-defined intervals—and transmits securely via WLAN, wired Ethernet (LAN), or testo’s proprietary UltraRange long-range radio protocol, eliminating dependency on local infrastructure in low-connectivity zones.

Key Features

• Integrated NTC temperature sensor with factory calibration certificate included
• Real-time visual alarm indication via programmable LED status light (flashing upon threshold violation)
• Modular architecture enabling seamless integration into existing testo Saveris communication gateways (e.g., testo Saveris 2 base station or testo UltraRange repeaters)
• Built-in monochrome LCD display for local verification of current reading, battery status, and alarm state
• Robust housing rated for operation in temperature ranges from –20 °C to +50 °C and relative humidity up to 95 % RH (non-condensing)
• Compliant with DIN EN 12830:2018 for temperature monitoring equipment used in refrigerated transport and storage
• Supports configurable measurement intervals from 1 second to 24 hours

Sample Compatibility & Compliance

The testo 150 T1 module is intended for non-invasive, ambient air temperature monitoring—not for direct immersion, surface contact, or aggressive chemical exposure. It is validated for use in GxP-critical environments where regulatory adherence is mandatory. The device supports full audit trail functionality when paired with testo Saveris PRO / CFR software, satisfying FDA 21 CFR Part 11 requirements for electronic records and signatures—including user authentication, change logging, and immutable data archiving. Its firmware and calibration documentation are structured to align with ISO/IEC 17025, EU Annex 15, and WHO TRS 961 guidelines for qualification of environmental monitoring systems. Each unit ships with an accredited calibration protocol traceable to DKD/DAkkS standards.

Software & Data Management

Data from the T1 module is centrally aggregated and managed through testo Saveris PRO (for cloud-hosted or on-premise deployment) or testo Saveris CFR (designed specifically for 21 CFR Part 11 compliance). Both platforms provide role-based access control, automated report generation (PDF/CSV), configurable alarm escalation (email/SMS), and real-time dashboards with trend visualization. The testo Saveris Cockpit remote access unit enables secure off-site oversight without requiring direct network exposure. All raw measurement data—including timestamps, sensor ID, and system event logs—is stored with cryptographic integrity, supporting retrospective review during regulatory inspections or internal quality audits.

Applications

• Continuous temperature monitoring in pharmaceutical cold chain logistics (warehouses, distribution centers, delivery vehicles)
• Stability testing chambers and accelerated aging studies per ICH Q1–Q5 guidelines
• Vaccine storage units (including ultra-low temperature freezers when deployed with appropriate external probes)
• Environmental qualification of cleanrooms, incubators, and biosafety cabinets
• Validation and routine monitoring of laboratory refrigerators, freezers, and incubation systems
• Compliance-driven monitoring for EU GDP, USP , and MHRA guidance on temperature-sensitive product handling

FAQ

Is the NTC sensor replaceable or field-calibratable?
No—the NTC sensor is permanently integrated and sealed within the module housing. Calibration is performed at the factory; field recalibration is not supported. Users must rely on periodic verification against a reference standard per their internal SOPs.
Does the module support external probe inputs?
No—model 0572 3350 contains only the built-in NTC sensor. For multi-sensor configurations, users should select the testo 150 T2 (dual NTC), T3 (NTC + humidity), or T4 (NTC + humidity + CO₂) variants.
What is the typical battery life under standard logging conditions?
With default 15-minute recording intervals and WLAN transmission enabled, battery life exceeds 12 months using the supplied AA alkaline cells. Battery status is continuously monitored and reported in the Saveris software dashboard.
Can the module operate independently without a gateway?
Yes—it logs locally even during network outages. Data is buffered in non-volatile memory and automatically synchronized once connectivity resumes, ensuring zero data loss during transient disruptions.
Is firmware update capability available remotely?
Yes—firmware updates can be deployed over-the-air via testo Saveris PRO/CFR, maintaining version control and compliance across large-scale deployments.
