testo 150 DIN2 Temperature Data Logger Module with Dual mini-DIN Interfaces

Overview

The testo 150 DIN2 is a CE-marked, DIN EN 12830:2018–certified temperature data logger module engineered for continuous, high-integrity environmental monitoring in regulated life science and pharmaceutical settings. As a core component of the testo Saveris Pharma ecosystem, it implements precision thermometry via two independent mini-DIN input channels—each designed to accept standardized Pt100 or NTC temperature probes compliant with IEC 60751 and DIN 43760. Its measurement principle relies on four-wire resistance-based sensing with cold-junction compensation, ensuring stable offset correction and long-term drift mitigation across ambient operating ranges (−20 °C to +60 °C). Unlike monolithic loggers, the DIN2 adopts a modular architecture that decouples sensor interfacing from communication infrastructure—enabling seamless integration into existing facility networks without hardware retrofitting.

Key Features

• Dual mini-DIN inputs supporting interchangeable, pre-calibrated Pt100/NTC probes—including Class A and Class B accuracy variants per IEC 60751
• Integrated OLED display for real-time channel values, status indicators, and alarm confirmation—no external interface required for basic operation
• Triple-mode connectivity: native IEEE 802.11n (WLAN), 10/100BASE-TX Ethernet (LAN), and optional testo UltraRange 2.4 GHz FHSS radio (up to 1 km line-of-sight range)
• Configurable visual alarm system: bi-color LED (red/green) with programmable flash patterns indicating limit violations, communication loss, or battery low condition
• Battery-powered operation using two AA alkaline cells (typical runtime ≥12 months at 15-min logging interval); wall-mount bracket and calibration certificate included
• Firmware upgradable via secure HTTPS connection; supports TLS 1.2 encryption for data-in-transit protection

Sample Compatibility & Compliance

The testo 150 DIN2 is validated for use with all testo-certified mini-DIN temperature probes—including surface, immersion, air, and penetration types—ensuring metrological consistency across diverse sample interfaces (e.g., incubators, cold rooms, stability chambers, lyophilizers). It meets the mandatory requirements of DIN EN 12830:2018 for temperature monitoring equipment used in refrigerated transport and storage of medicinal products. Its design aligns with EU GMP Annex 15, FDA 21 CFR Part 11 (when deployed with testo Saveris PRO/CFR software), and ISO 13485 quality management systems. All firmware and configuration parameters are subject to electronic audit trail generation, supporting full ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) data integrity compliance.

Software & Data Management

Data acquisition, validation, and reporting are managed through testo’s validated software suite: testo Saveris PRO (for 21 CFR Part 11–compliant environments) or testo Saveris Cockpit (cloud-based remote access). The module transmits timestamped, digitally signed measurement records—including raw resistance values, calculated temperatures, and diagnostic metadata—to centralized databases. Role-based user access control, electronic signatures, and automated report generation (PDF/CSV) are supported. Audit trails capture all configuration changes, calibration events, and alarm acknowledgments with immutable timestamps—fully traceable for regulatory inspections and internal QA audits.

Applications

• Continuous temperature mapping of pharmaceutical cold chain logistics (warehouses, trucks, shipping containers)
• Environmental qualification of cleanrooms, stability testing chambers (ICH Q1/Q5), and vaccine storage units
• Process validation support for sterilization cycles (autoclaves, depyrogenation tunnels) where probe placement flexibility is critical
• Monitoring of bioreactor jacket cooling loops and HVAC supply ducts in GMP manufacturing facilities
• Backup validation logging during routine maintenance of primary control systems

FAQ

Does the testo 150 DIN2 support external humidity or CO₂ sensors?
No—it is dedicated exclusively to temperature measurement via mini-DIN interfaces. For multi-parameter monitoring, integrate with testo 150 HUM (humidity) or testo 150 CO₂ modules within the same Saveris network.
Is firmware update capability available over radio transmission?
Firmware updates require a wired LAN or WLAN connection; UltraRange radio is limited to measurement data transmission only.
Can alarm thresholds be configured per channel independently?
Yes—upper/lower limits, hysteresis, and alarm persistence duration are fully configurable per channel via Saveris software.
What is the maximum recommended logging interval for battery longevity?
At 15-minute intervals, battery life exceeds 12 months under typical conditions; intervals ≤5 minutes reduce runtime proportionally and may require periodic replacement.
Is the module suitable for use in explosion-hazardous areas (ATEX zones)?
No—the testo 150 DIN2 is not intrinsically safe and lacks ATEX or IECEx certification; it is intended for general laboratory and facility environments only.
