TESTO 175 T2 Temperature Data Logger, 2-Channel NTC, 1 Million Readings, -35 to +55 °C Internal, -40 to +120 °C External, IP65, USB Interface, LCD Display 0572 1752

Monitoring temperature-sensitive goods during storage and transport is critical to prevent spoilage, regulatory non-compliance, and costly losses. The TESTO 175 T2 temperature data logger provides reliable, unattended recording of ambient and probe-based temperatures, ensuring complete documentation for quality assurance and cold chain validation.

Who is it for

This data logger is ideal for warehouse managers, logistics coordinators, laboratory technicians, and food or pharmaceutical quality officers who need accurate, long-term temperature monitoring with minimal maintenance. It suits both stationary use in storage rooms and mobile use in refrigerated vehicles or containers.

Main features

• Dual-channel measurement: one internal NTC sensor and one external NTC probe connection for simultaneous ambient and product temperature monitoring.
• Wide measurement range: internal sensor from -35 to +55 °C; external sensor supports -40 to +120 °C depending on probe.
• High accuracy: ±0.5 °C internal and ±0.3 °C system accuracy with typical external probe.
• Massive memory: stores up to 1,000,000 measurement values, enabling months of logging without download.
• Flexible logging interval: adjustable from 10 seconds to 24 hours to match application needs.
• Long battery life: up to 3 years at 15-minute measurement rate using 3 AAA batteries.
• Rugged design: IP65 protection against dust and water jets, suitable for harsh environments.
• Clear LCD display shows current readings, alarm status, and battery level at a glance.
• Configurable visual and audible alarms for immediate alert when thresholds are exceeded.
• Easy data transfer via mini USB to PC; compatible with free ComSoft Basic software and optional ComSoft Professional for advanced analysis.

Tips

For cold chain applications, pair the 175 T2 with an external probe placed inside the product or packaging to capture true product temperature rather than ambient air. Calibrate the logger annually or according to your quality system to maintain measurement accuracy. Use ComSoft Professional to generate PDF reports that meet regulatory documentation requirements.
