Handheld Altimeter Barometer Thermometer

Compact handheld device measuring 9 x 5 x 2 cm and constructed from impact-resistant ABS plastic. Delivers simultaneous real-time readings of altitude (absolute and relative), barometric pressure, and ambient temperature. Offers 12–24 hour weather trend prediction based on local pressure analysis (effective range: 30–50 km). Fully configurable display units: altitude (metres or feet), temperature (Celsius or Fahrenheit), and pressure (hPa, inHg or mmHg). Operates on a single CR2032 button battery (not supplied). Includes English instruction manual. No setup or calibration needed — displays accurate baseline values immediately after battery insertion and power-on.
