DataTrace Humidity Data Loggers
[2 Models]DataTrace offers two high-accuracy humidity data loggers for monitoring temperature and relative humidity in regulated production, storage, transportation and validation applications.
The compact MPIII records measurements internally for later analysis, while the wireless MPRF provides real-time process visibility. Both models measure from 0% to 100% RH and operate across temperatures from 0°C to +85°C.
- High-accuracy humidity and temperature monitoring
- Ideal for stability studies and environmental qualification
- FDA 21 CFR Part 11 compliant software
Full-range humidity monitoring
Measure relative humidity across the full 0% to 100% RH range, together with temperatures from 0°C to +85°C.
Two data-collection options
Select the self-contained MPIII for onboard data logging or the MPRF when measurements need to be transmitted and reviewed in real time.
Compact, durable construction
Both models use robust stainless-steel construction designed for demanding production and validation environments.
Traceable calibration
NIST-traceable factory calibration supports dependable measurements and documented quality processes.
DataTrace MPIII and MPRF humidity data loggers are designed for processes where changes in temperature or relative humidity could affect product quality, process performance or compliance.
- Pharmaceutical production monitoring
- EtO sterilisation
- Steriliser validation
- Incubator validation
- Food production and drying
- Controlled storage environments
- Critical product shipments
- Environmental qualification studies
Choose the compact MPIII for self-contained monitoring and post-process analysis, or the wireless MPRF when conditions need to be viewed in real time.
Temperature and Humidity Monitoring
Measure relative humidity across the full 0% to 100% RH range and temperatures from 0°C to +85°C using a single compact logger.
Standalone or Real-Time Data
Choose the MPIII for self-contained data logging or the wireless MPRF for real-time visibility while your process is underway.
High Measurement Accuracy
Both models provide temperature accuracy of ±0.1°C and humidity accuracy of ±2% RH in non-condensing environments.
NIST-Traceable Calibration
Factory calibration provides traceable measurement data to support validation, quality control and regulatory requirements.
Durable Construction
Stainless-steel construction supports reliable operation in demanding production, storage, transportation and sterilisation environments.
Secure Data Management
DT Pro software supports study configuration, data analysis and secure reporting in accordance with FDA 21 CFR Part 11 requirements.
Intrinsically Safe Options
ATEX certification supports suitable use within applications where intrinsic safety is required.
