largely maintenance free in normal, clean air |
| Measuring/working range |
0 to 100% rH |
| Medium |
air, unpressurized, not corrosive |
| Accuracy (incl. hysteresis, non-linearity and repeat accuracy) |
±(1.5 + 0.5% x measured value) % rH; (at <90% rH; -15 to +40°C)
2.5% rH; (at >90% rH; -15 to +40°C)
