• Accurate Humidity Measurement: Utilizes the proven wet-bulb/dry-bulb principle for reliable relative humidity calculation.
• Two Thermometers: Features one standard (dry bulb) thermometer and one with a moistened wick (wet bulb).
• Humidity Calculation: Readings are used with a psychrometric chart or table (included) to determine relative humidity.
• Essential for Incubation/Brooding: Critical for maintaining optimal moisture levels vital for hatch rates and chick health.
• Reliable & Battery-Free: Traditional, dependable method that requires no batteries (requires water for the wick).

Measuring humidity is as important as temperature in many aspects of poultry farming in Africa, especially during incubation, and early brooding and rearing. The Poltek Wet & Dry Bulb Hygrometer provides a reliable and accurate method for measuring relative humidity and temperature. It consists of two thermometers mounted together: one measures the ambient air temperature (dry bulb), while the other has its bulb covered by a wet wick, measuring the evaporative cooling effect (wet bulb). The difference between these two readings, when referenced against a psychrometric chart or calculation table (provided), gives an accurate measure of relative humidity. This instrument is a fundamental tool for farmers needing precise environmental control.
