Digital Pen‑Type Thermo‑Hygrometer – Temperature & Humidity [0555]

The Digital Pen‑Type Thermo‑Hygrometer is a compact, high‑accuracy instrument designed for measuring air temperature and relative humidity (%RH) in educational and laboratory environments. Ideal for KS3 and above, this easy‑to‑use meter simultaneously displays both readings on a clear LCD screen, making it perfect for classroom demonstrations, practical investigations, and fieldwork.

The integrated sensors are housed within a protective grille, allowing accurate measurements in air streams while protecting sensitive components. The grille can be opened during use and closed for protection when not in operation, enhancing durability and reliability in busy school environments.

Temperature readings can be displayed in °C or °F, while humidity is shown as %RH. The large 58 × 12mm LCD display provides clear visibility, and the min/max memory function allows users to track environmental changes over time. The impact‑resistant ABS casing ensures robustness during regular handling.

Supplied with a battery and protective hard case, the instrument is ready for immediate use. Each unit is issued with a CAL‑HT calibration certificate, confirming calibration at 20°C and 40°C, and at 35% and 75% RH @ 20°C, providing confidence in measurement accuracy.
