Extech Big Digit Indoor/Outdoor Thermometer with Temperature Alarm

The Extech Big Digit Indoor/Outdoor Thermometer provides continuous monitoring of two distinct environments simultaneously. Featuring a large LCD display with easy-to-read 1-inch (25mm) digits, it clearly shows both the indoor temperature from its built-in sensor and the outdoor temperature from a connected external probe.

A key feature is its user-programmable high and low audible temperature alarms for the external probe. This allows you to set critical thresholds for applications like freezer monitoring, greenhouse control, or room temperature management, receiving an instant alert if temperatures fall outside your specified safe range.

The unit includes a wired, water-resistant external sensor with a long 9.6-foot (3-metre) thin cable. This flexible design enables easy installation through windows, doors, or small openings to monitor outdoor conditions, or it can be placed inside refrigerators, freezers, or other temperature-controlled rooms.

Key Features:

• Dual Display: Monitors and displays indoor and outdoor temperatures at the same time.
• Programmable Alarms: Set custom high and low audible alarms for the external probe temperature.
• Min/Max Memory: Internal memory function records and stores the minimum and maximum temperature readings over time for later review.
• Versatile Mounting: Includes a built-in stand for desktop use and a mounting bracket for secure wall display.
• High-Resolution Reading: Offers a precise 0.1°F/°C resolution with a basic accuracy of ±1.8°F (±1°C).

Ideal for homes, offices, server rooms, greenhouses, and commercial refrigeration, this thermometer offers reliable monitoring and vital alerting functions to protect your assets and ensure optimal environmental conditions.
