The Model 5640 Humidity-Temperature-Dew Point Meter is designed to provide fast, accurate measurements in virtually any situation. This precision instrument is capable of measuring relative humidity over the range of 5 to 95% R.H. and temperature from 32 to 122°F (0-50°C). Accuracy is ±3% for humidity and ± 0.7°F (± 0.4°C) for temperature which can be displayed in either °F or °C. Dew point is easily calculated at the touch of a button.
The indicator has a memory function to display preprogrammed MINimum and MAXimum values and operates from a single 9V alkaline battery with typical operating life of 100 hours. When battery life drops to approximately 10 hours, the “BAT LOW” indicator activates.
