About This Instrument
The Vartech THM S1 is a compact digital thermo-hygrometer with a built-in 12/24-hour clock. It simultaneously displays temperature (-10 °C to +50 °C / +14 °F to +122 °F), relative humidity (20–90 % RH) and the current time on a 3-line LCD. A comfort level indicator visually signals whether ambient conditions are comfortable. Min./Max. memory records the extremes of both temperature and humidity. °C / °F switching allows use with either scale. At just 9.8 × 5.8 × 1.3 cm it is well-suited for home, office, storage rooms, server rooms and any space where temperature and humidity monitoring is required. Powered by a single 1.5 V AAA battery. Note: this is a consumer-grade instrument and not intended for industrial applications.
