WH58D/WH59D

This Repetitive Temperature Recorder is a robust data logging device designed for cyclic temperature monitoring across two key ranges: a standard span of -100°C to 150°C and an extended low-temperature span from -200°C to 150°C. It automatically records temperature at preset intervals, storing data internally for later retrieval and analysis, making it ideal for applications requiring periodic profiling rather than continuous monitoring.

Commonly used in freeze-thaw cycle testing, thermal chamber validation, environmental stress screening (ESS), and stability studies, it is essential in industries like pharmaceuticals, food storage, aerospace, and logistics. Its core function is to reliably capture precise temperature data over repeated cycles, helping users verify process control, validate equipment performance, and ensure product integrity.

Key features typically include a durable sensor, programmable recording intervals, a secure data memory, software for graph and report generation, and a compact, often battery-powered design for placement in confined spaces like freezers, incubators, or during transit. This recorder provides a critical, verifiable record for quality assurance, compliance, and process optimization in demanding thermal environments.
