Dual indoor/outdoor digital thermometer with clear backlit LCD and 1.5 m external sensor cable — ideal for monitoring cabin and external temperatures simultaneously. Key benefits Know both inside and outside temperatures at a glance: Dual-sensing display prevents surprises and helps you make quick decisions about heating, cooling, and ventilation. Reliable readings across a wide range: Indoor range -20 °C to +70 °C and outdoor range -50 °C to +70 °C cover extreme conditions and everyday use. Easy to read in any light: Backlit LCD with selectable blue, red, or green digital display makes temperature checks quick and accurate day or night. Flexible placement for accurate external readings: The 1.5 meter sensor cable lets you place the external probe where it best measures outdoor or engine-bay conditions without moving the display. Space-saving, vehicle-friendly design: Compact black housing (7.6 x 3.4 x 1.5 cm) fits discreetly on dashboards, consoles, or other small spaces. What it does and why it matters Simultaneous monitoring: Displays indoor and outdoor temperatures at once so you can compare conditions and adjust ventilation or climate controls accordingly. Wide temperature coverage: Measures very low and high temperatures that typical thermometers don’t handle, useful for cold weather prep or monitoring high-heat environments. Visible in any environment: The backlit, color-selectable LCD keeps information readable during daytime glare and nighttime driving. Key specifications Indoor temperature range: -20 °C to +70 °C Outdoor temperature range: -50 °C to +70 °C External sensor cable length: 1.5 meters Display: Backlit LCD with optional blue, red, or green digital color Housing color and size: Black, 7.6 x 3.4 x 1.5 cm Compatibility and placement Designed for vehicle interiors but suitable for other small environments where simultaneous indoor/outdoor temperature monitoring is useful. Place the display on a dashboard, console, or shelf; route the 1.5 m sensor cable to the external spot you need to monitor (under a window, near an intake, or outside a vehicle). No special integrations required — functions independently as a dedicated temperature display. Practical applications Road trips and winter travel: Monitor cabin comfort while keeping track of outside freezing temperatures to plan rest stops and driving speed. Engine or equipment monitoring: Run the external probe near an engine bay, battery compartment, or external equipment to keep an eye on heat exposure without relocating the display. Home garage or workshop: Position the display inside while the external sensor measures outdoor or isolated work areas to balance ventilation and heating. What makes it stand out True dual-sensing capability with wide measurement ranges and a long external cable for flexible, accurate placement. Clean, compact design that integrates into vehicle interiors without obstructing sightlines or controls. Clear, backlit digital display with selectable color options for comfortable viewing in any lighting condition.
