The HTC-2 Digital Indoor/Outdoor Thermo-Hygrometer is a high-precision, dual-zone monitoring device designed for both residential and professional environments. At Electrapac, we recommend this model for users who need to track environmental conditions in two different locations simultaneously, such as inside a greenhouse and outside, or inside a server room and the hallway.

Product Overview

The HTC-2 features a large, easy-to-read LCD screen that displays temperature, humidity, and time. Its standout feature is the external waterproof probe on a 1.5-meter cable. This allows you to keep the main unit indoors while the probe measures the temperature of the outdoors, a refrigerator, or a specialized incubation chamber.

Key Features for Electrapac Customers

• Dual Temperature Monitoring: Displays both "In" (Local) and "Out" (Probe) temperatures on the screen at the same time.

• Max/Min Memory: Automatically records the highest and lowest temperature and humidity readings since the last reset—essential for tracking overnight fluctuations.

• Integrated Clock & Alarm: Includes a 12/24 hour clock and a daily alarm function, making it a perfect desk or wall companion.

• Large LCD Display: Features bold, high-contrast digits that can be read from across a room.

• Flexible Mounting: Equipped with a fold-out stand for tabletop use and a hanging hole for wall mounting.

• Switchable Units: Easily toggle between Celsius (°C) and Fahrenheit (°F) based on your preference.

Setup & Usage Guide

To get the most accurate readings from your Electrapac HTC-2:

1. Probe Placement: Ensure the external probe is not in direct sunlight or touching a hot/cold metal surface, as this will result in "ghost" readings.

2. Indoor Positioning: Keep the main unit away from air conditioning vents or heaters to ensure the "Indoor" reading reflects the true ambient room temperature.

3. Battery Care: Use a high-quality AAA battery. If the display becomes faint, replace the battery immediately to maintain sensor accuracy.

4. Button Functions:

   • MODE: Switch between Clock and Alarm.

   • ADJ: Adjust the time/date/alarm.

   • MAX/MIN: View the stored peak and lowest values.

Primary Applications

• HVAC & Industrial: Monitoring the temperature difference between supply and return air in ventilation systems.

• Agriculture & Gardening: Placing the probe inside a hydroponic grow tent while keeping the display outside for easy checking.

• Food Storage: Keeping the probe inside a freezer or refrigerator while the display stays safely on the outside door.

• Pet Care: Monitoring the specific "basking spot" temperature in a reptile terrarium or bird incubator.

• Home Comfort: Tracking the efficiency of home insulation by comparing indoor vs. outdoor temperatures.
