HTC-2 Digital Thermometer Hygrometer & Clock with Sensor Probe

HTC-2 Digital Thermometer Hygrometer Clock Calendar with Sensor Probe

Product Description

The HTC-2 Digital Thermometer Hygrometer is a compact, multifunctional monitoring device designed to track indoor and outdoor temperature alongside indoor humidity, all from a single unit. Its large LCD display shows temperature, humidity, and time simultaneously, making it easy to check environmental conditions at a glance without cycling through multiple screens or separate devices.

At the core of the HTC-2 is a dual-sensor setup: an internal sensor measures indoor temperature and humidity, while a wired external probe, connected via a 1.5-meter cable, extends outdoors through a window or door gap to capture outdoor temperature readings. This setup lets users compare indoor comfort against outside conditions without needing a separate outdoor unit or wireless transmitter, which keeps the device simple to set up and free of pairing or signal-range issues common with wireless weather stations.

Measurement performance covers a practical range for most households: indoor temperature from -10°C to +50°C and outdoor temperature from -50°C to +70°C via the probe, both with 0.1°C resolution and ±1°C accuracy. Indoor humidity is tracked from 10% to 99% relative humidity, with 1% resolution and ±5% accuracy, giving a reasonably precise picture of indoor air conditions for everyday comfort monitoring.

Beyond basic temperature and humidity readings, the HTC-2 includes a clock and calendar function with selectable 12-hour or 24-hour display, a daily alarm, and an optional hourly chime for time awareness throughout the day. A maximum/minimum memory function records the highest and lowest temperature and humidity values recorded, which is useful for tracking daily fluctuations or checking overnight lows without needing to watch the display continuously. A comfort index feature further interprets current conditions, indicating whether the environment reads as comfortable, wet, or dry based on the combined temperature and humidity data.

Physically, the HTC-2 is built from ABS plastic and designed for flexible placement, either standing on a desk or shelf using its fold-out stand, or mounted on a wall using the built-in hanging slot. It runs on a single AAA battery, keeping power consumption low and battery life long between replacements.

This combination of dual-location temperature tracking, humidity monitoring, and everyday clock functions makes the HTC-2 a practical addition to homes, offices, greenhouses, or any space where keeping an eye on both indoor comfort and outdoor conditions matters.
