LogTag HASO-8 is a disposable humidity and temperature data logger designed to monitor environmental conditions during the transport and storage of sensitive goods such as food, pharmaceuticals, vaccines, and medical devices.
| Product Model | HASO-8 |
| Sensor Measurement Range | -40°C to +85°C (-40°F to +185°F) |
| Operating Temperature Range | -40°C to +85°C (-40°F to +185°F) |
| Storage Temperature Range | +10°C to +50°C (+50°F to +122°F) |
| Humidity Measurement Range | 0% RH to 100% RH (non-condensing), with limitations |
| Humidity Operating Range | 0% RH to 100% RH (non-condensing), with limitations |
| Storage Humidity Range | 20% RH to 65% RH |
| Rated Temperature Reading Accuracy | Better than ±0.45°C (±0.8°F) for +0°C to +50°C (+32°F to +122°F), typically ±0.3°C (0.6°F). Better than ±0.8°C (±1.4°F) for +50°C to +80°C (+122°F to +176°F), typically ±0.5°C (0.9°F). Better than ±0.95°C (±1.7°F) for -40°C to +0°C (-40°F to +32°F), typically ±0.6°C (1.1°F). Actual performance is typically much better than the rated values. Accuracy figures can be improved by recalibration. |
| Rated Humidity Reading Accuracy | Better than ±5%RH for 10%RH to 80%RH. Better than ±6%RH for 0%RH to 10%RH. Better than ±7%RH for 80%RH to 100%RH. Actual performance is typically much better than the rated values. Accuracy figures can be improved by recalibration. |
| Humidity Resolution | Better than 0.1% RH. |
| Temperature Resolution | Better than 0.1°C or 0.1°F |
