| Temperature Sensor | |
| Operation range | -40° to 158°F (-40° to 70°C) |
| Stability (drift) | 0.18°F (< 0.1°C) per year |
| Accuracy | ±0.38°F from 32° to 122°F (±0.21°C from 0° to 50°C); see Plot A |
| Resolution | 0.02°C at 25°C (0.04°F at 77°F); see Plot A |
| Response Time | 40 minutes in air moving 1 m/sec |

| Operation rang | 0-100% RH, -40° to 158°F (-40° to 70°C) Exposure to conditions below -4°F (-20°C) or above 95%. RH may temporarily increase the maximum RH sensor error by an additional 1% |
| Accuracy | ±2.5% from 10% to 90% RH (typical), to a maximum of ±3.5% including hysteresis. See Plot B for full range. |
| Resolution | 0.03% |
| Response Time (typical to 90%) | 40 minute in air moving 1 m/sec with protective cap |
| Logger | |
| Operation range | -40° to 158°F (-40° to 70°C) |
| Memory (non-volatile) | 64K bytes memory (approx. 21,000 temperature and RH measurements) |
