 With a 10-year battery and internal memory for one million readings, the SRX6 Precision Thermocouple Logger is built for long deployments and minimal maintenance. Whether you're collecting months of high-resolution data or monitoring hard-to-reach locations, you can trust it to keep recording—without the need for power cables, recharging, downloading, or constant oversight.

 
The SRX6 has been designed for demanding fieldwork, lab testing, and industrial applications. It’s trusted in everything from cryogenic monitoring to concrete maturity and high-heat processing environments. With support for standard thermocouple types and long battery life, it’s a flexible, dependable tool for capturing detailed thermal profiles—even in harsh conditions.

 • Seven Independent Thermocouple Inputs

Flexibly configure each of the seven channels to support Type J, K, T, E, or S thermocouples for multi-point or mixed-type measurements.
• High Resolution 16-Bit Data1
Delivers enhanced accuracy and fine-grained resolution—up to 0.04° C in sensitive temperature ranges
• Calibration Flexibility
Support for multi-point calibration lets you optimize accuracy across your specific measurement range using ACR’s TrendReader TRX Pro software.
• Tough Environmental Performance
Operates reliably from –40° C to +85 °C (logger body), suitable for harsh industrial, refrigerated, or outdoor settings.
• Wide Temperature Range: –200 °C to +1 ,700 °C
The SRX6 supports measurements across a broad temperature range—from cryogenic conditions to high-temperature industrial applications.
• Self-Powered Long Life Battery
Runs for up to 10 years1 on internal batteries, with no need for recharging or external power—well suited for long-term deployments in the field or hard-to-access locations.
• Large Internal Memory - One Million Readings
The ample storage provides flexibility for a range of applications—reducing the need for memory-saving strategies and helping ensure that longer or more detailed logging sessions can run without interruption.
• Integrated Two-Stage Alarm Output
Dual open-drain outputs allow direct integration with alarms, lights, or PLCs for both warning and critical conditions.
