mht 50 dataloger
The MarMonix MHT-50 provides unbroken audit-trail compliance during vaccine distribution, biopharmaceutical air-freight, and refrigerated perishable shipping by continuously logging critical temperature (±0.5°C) and relative humidity (±3% RH) thresholds across multi-day transit routes without requiring dedicated software.
MarMonix MHT-50 temperature and humidity data logger Overview
The MarMonix MHT-50 is a compact, high-precision, single-use USB temperature and humidity data logger engineered for strict environmental validation during logistics, cold storage, and cleanroom monitoring. Designed for immediate field deployment, it features an IP66 water- and dust-resistant casing, internal precision sensors, and pre-configured or customizable logging intervals ranging from 1 minute up to 24 hours.
Upon reaching the destination, users simply connect the MHT-50 directly to any standard computer USB port. The device automatically generates tamper-evident PDF analytical reports and raw CSV datasets instantly—eliminating software installation friction and accelerating cargo release workflows.
