LogTag® Vaxtag® is a specialized temperature monitoring device for vaccine refrigerators in healthcare facilities and intermediate storage areas, complying with WHO PQS standards. The device features a display and data logging capabilities, allowing for quick viewing of temperature and time statistics over several days. When the temperature exceeds the set threshold, the device displays a visual alert. Data can be viewed directly on the screen or downloaded via the LogTag® Analyzer software for analysis, storage, and management.
| Product Model | TRID30-7FW (Vaxtag) |
| Sensor Measurement Range | -30 °C to +60 °C (-22 °F to +140 °F) |
| Operating Temperature Range | -30 °C to +60 °C (-22 °F to +140 °F) |
| Storage Temperature Range | -10 °C to +40 °C (-14° F to +104 °F) |
| Rated Temperature Reading Accuracy | Better than ±0.5 °C (±0.9 °F) for measurements from -20 °C to +40 °C (-4 °F to +104 °F), typically ±0.3 °C (0.6 °F) Better than ±0.8 °C (±1.5 °F) for other measurements - typically ±0.5 °C (0.9 °F) Actual performance is typically much better than the rated values. Accuracy figures can be improved by recalibration |
| Rated Temperature Reading Resolution | 0.1 °C (0.2 °F) for measurements -30 °C to +40 °C (-22 °F to +104 °F) 0.2 °C (0.4 °F) for measurements above +40 °C (+104 °F) LogTag® Analyzer currently displays to one decimal place of °C or °F. The native resolution is what is stored in the LogTag® |
