Buying Guide
- Data point capacity: Choose the number of data points that matches your monitoring duration and sampling rate. Higher capacity supports longer monitoring without data gaps.
- Connectivity: USB-only models are simple and reliable for on-device PDF/CSV exports; Bluetooth-enabled models offer wireless data transfer and easier app-based analysis.
- Reports and export formats: PDFs are common for submission records; CSV/Excel formats are preferred when data needs further processing in spreadsheets or LIMS systems.
- Calibration and standards: For pharmaceutical or vaccine storage, look for models with calibration certificates and adherence to CDC FDA Part 11 or equivalent.
- Display and usability: LCD displays help quick checks in the field. Consider models with clear max/min, current temp, date, and point counter visibility.
- Protection and form factor: IP ratings (like IP65) and rugged housings are important in dusty, wet, or cold environments. Pen-shaped forms can fit tight gaps.
- Temperature range and accuracy: Ensure the device covers your required range with adequate precision (e.g., ±0.3°C or ±0.9°F as noted on several Elitech models).
- Multi-channel needs: If monitoring multiple locations or products simultaneously, a multi-channel logger (e.g., 4 channels) may be necessary.
- Software requirements: Some models require PC software for full data access; others offer full export via USB without software installation.
