Advanced Dual-Zone Monitoring: The HTC-2 Thermometer with Probe
For agricultural specialists, hardware engineers, and DIY hobbyists, standard room thermometers simply aren't enough. The HTC-2 is engineered to solve a specific problem: monitoring two completely different environments at the exact same time. By utilizing its built-in internal sensor alongside an extended wired external probe, you can track ambient room conditions while simultaneously measuring the extreme temperatures inside an enclosure.
Disclaimer for our buyers: To set the right expectations, this device measures humidity ONLY on the main indoor unit. The external wired probe is strictly for temperature measurement (-50°C to +70°C). It is a standalone battery-powered tool and does not feature data-logging exports or wireless connectivity.
Core Capabilities
Simultaneous IN/OUT temp display. External probe reads extreme temps (-50°C to 70°C). Main unit tracks indoor humidity (10%-99%). Includes clock, calendar, and Max/Min data recall.
Industrial & Agricultural Applications
If you need precise micro-climate management, the HTC-2 is your primary tool. Poultry farmers use the main unit to track the ambient barn while dropping the external probe directly into chick brooders or egg incubators. Hydroponic growers use the probe to monitor Deep Water Culture (DWC) nutrient reservoirs while tracking greenhouse humidity. It is also highly effective for reptile terrariums, cold-chain transport coolers, and HVAC duct testing, allowing you to see the temperature difference between two zones at a single glance
Hardware & Performance Data
Unlike standard monitors, the HTC-2 handles a much wider thermal range. The Indoor Temperature Range covers -10°C to 50°C (14°F to 122°F), while the Outdoor Probe Range extends from an extreme -50°C up to 70°C (-58°F to 158°F). Humidity Monitoring operates from 10% to 99% RH on the main unit. The device maintains a strict Accuracy Variance of ±1°C and ±5% RH. Navigating the data is simple using the 3-Button Interface, and the unit is entirely powered by a highly efficient 1.5V AAA battery system.
