The JR-2000 provides dependable temperature monitoring in a small, self-contained form factor that makes setup simple and data collection effortless.
Place the logger where needed, start logging, and later plug it directly into a USB port to download results — no interface cables or readers required.
Designed for users who value simplicity, compact size, and reliability, the JR-2000 combines a wide measurement range of −40 °C to +85 °C (−40 °F to +185 °F) with excellent accuracy and long-term battery performance, even in cold environments. Its multi-color LED gives a clear visual indication of operating status and alarm conditions at a glance.
With capacity for more than 100 000 readings and sampling intervals configurable from 10 seconds to 18 hours, the JR-2000 suits both short studies and long-term monitoring projects. Typical applications include cold-chain verification, laboratory and storage temperature tracking, building performance assessments, and HVAC testing.
The JR-2000 works seamlessly with TrendReader TRX, ACR’s latest generation of data logging software, offering modern interface design, powerful analysis tools, and full compatibility with current Windows operating systems. For existing users, the logger also remains compatible with TrendReader Jr software.

Data loggers are often used in highly regulated environments such as food and pharmaceutical production and storage where strict safety regulations apply. Regulatory agencies generally require proof of calibration.
ACR calibrations are performed using reference standards that have been calibrated and are traceable to the US National Institute of Standards & Technology (NIST). This ensures that all ACR data loggers meet, and perform to, their published specifications, allowing you to be confident that they will assist you in achieving your compliance requirements.
Calibration certificates are provided with every calibration we perform. ACR Systems is an ISO 9001:2015 registered company and calibration records are kept as part of our quality system and can be made available for customer audits.
