Pen-Size Meter that Measures Humidity & Temperature Including Min/Max & Delta.

Technicians in HVAC, labs, industry and environmental studies can carry this sturdy metal pen anywhere for quick readings of RH (Relative Humidity) and ambient temperature. Simultaneously displays RH and temperature in °C or °F. Will also show a continually updated ∆ delta (difference) from a starting point.
