Digital Hygro Thermometer ( HTC – 103-CTH )

The HTC 103‑CTH Digital Thermo‑Hygrometer is a reliable and elegantly designed environmental monitoring instrument, perfect for homes, offices, laboratories, greenhouses, and controlled storage spaces. Its dual-line LCD displays temperature, humidity, and time at a glance—making it ideal for users who require real-time awareness of indoor conditions with added calendar and alarm clock features.

This compact instrument measures temperature from –50 °C to +70 °C (–58 °F to +158 °F) with a resolution of 0.1 °C and an accuracy of ±1.0 °C (±1.8 °F). It also displays relative humidity in the wide range of 10 % to 99 % RH, with ±5 % RH accuracy between 35 % and 75 % and up to ±10 % outside that range. These features enable fast and dependable environmental readings across diverse conditions.

Featuring a generous two-line display, the device allows simultaneous display of temperature, humidity, and time, reducing the need for toggling screens. The display supports both °C and °F units, and it includes MAX/MIN memory for recording historical temperature and humidity extremities—ideal for understanding environmental trends across hours or days.

The calendar with alarm clock and 12/24‑hour time format offers additional utility, converting this meter from a local measuring instrument into a functional desktop organizer with timekeeping and alert capabilities. Users can set alarms and view current date information seamlessly.

Powering the device is a single AAA 1.5 V battery, offering long-lasting performance with low power consumption. A low battery indicator ensures you are alerted before power runs out—the entire unit is lightweight and user-friendly for wall or desk mounting.

The operating temperature range spans from 0 °C to 50 °C, ensuring stable performance across typical indoor environments. Its built-in comfort index indicator categorizes conditions as “COMFORT”, “DRY”, or “WET” based on combined temperature and humidity readings—helping users easily assess indoor air quality.

Constructed with durable plastic and featuring a sleek white-and-black design, this hygrometer is both functional and decorative. Its slim dimensions (approx. 110 × 100 × 21 mm) and light weight (~100–150 g) make it easy to install using the integrated base or wall mount, and convenient for repositioning as needed.

Beyond aesthetics and ease-of-use, safety and accuracy are built-in. The device provides consistent readings—especially within the mid-humidity and moderate-temperature ranges—and offers a warranty for reliability assurance.

This hygrometer is especially suited for:

• Monitoring indoor climate in homes, offices, laboratories, and greenhouses

• Maintaining comfort and safety conditions in patient rooms, nurseries, and care facilities

• Tracking environmental conditions for storage areas like archives, pharmaceutical vaults, and cellular data centers

• Supporting scientific and academic use in classrooms and controlled settings

• Combining data tracking, alerting, and timekeeping in one unified, easy-to-install unit
