Dual-Zone Digital Reptile Thermometer & Hygrometer with Wired Probe

Never guess what’s going on inside your terrarium again! The TA318 Dual-Zone Digital Thermometer & Hygrometer allows you to monitor two separate temperature microclimates at once, plus ambient humidity—making it an incredible, cost-effective tool for dialing in thermal gradients across hot and cool sides.

Equipped with a 1.5-meter (4.9 ft) flexible wired probe sensor, you can easily place the probe tip directly on a basking ledge, inside a warm hide, or down on the substrate while keeping the main digital display mounted neatly outside the tank.

Key Features & Highlights

• Dual Temperature Readings: Displays both "IN" (main unit body temperature) and "OUT" (wired probe sensor temperature) simultaneously on a clear, high-contrast LCD screen.
• 1.5m Extended Sensor Probe: Generous 1.5-meter probe cable allows for precise probe placement right where your reptile rests, feeds, or basks.
• Integrated Hygrometer: Tracks indoor relative humidity from 25% RH to 98% RH to ensure proper shedding and hydration conditions.
• MAX/MIN Memory Recalls: Easily recall the highest and lowest recorded temperatures and humidity levels to spot nighttime dips or midday heat spikes.
• Wide Thermal Range:Probe/Outdoor: -40°C to 70°C (-40°F to 158°F)Main Unit/Indoor: 0°C to 50°C (32°F to 122°F)
• Versatile Mounting Options: Features both a flip-out table stand for shelf placement and a rear hanging slot for wall or rack mounting.
• °C / °F Switchable: Convenient toggle switch on the back lets you choose your preferred temperature scale.
• Power: Operates on 1 x AAA battery (not included).

Keeper’s Note & Pro-Tip

Pro-Tip: Run the thin probe cable behind background decor or through a mesh terrarium cable port, securing the probe tip with a suction cup or zip-tie directly at your pet's favorite basking site. Mount the display unit on the outside wall of the enclosure so you can check warm-side and cool-side metrics at a glance without disturbing your animal!
