DC-40-Temperature Fruit and Vegetable Room Display is a purpose-built solution designed to provide accurate, highly visible room temperature monitoring for agricultural and food processing environments. This custom order is heading to McCall Farms, a plant and vegetable farm focused on maintaining precise environmental conditions to protect product quality, ensure consistency, and support operational efficiency. In facilities where temperature stability directly impacts freshness and storage outcomes, having a dependable and easy-to-read display is essential.

The DC-40 model is primarily intended for indoor use, making it ideal for fruit and vegetable storage rooms, processing areas, packaging zones, and climate-controlled facilities. While it can be used outdoors in certain conditions, this configuration is optimized for indoor environments where consistent monitoring is required. Its main function is simple yet critical: measure and clearly display the ambient room temperature in a given area so staff can verify conditions at a glance.

At the core of the system is the electronic temperature probe, mounted externally and protected by a durable plastic housing. The probe continuously measures the surrounding air temperature and relays the data to the display unit. The entire system is powered by a 120 VAC wall adapter, ensuring reliable and steady operation without the need for complex wiring.

One of the key user-adjustable features of the DC-40 is the ability to switch between Celsius and Fahrenheit. The unit may ship displaying temperature in Celsius—for example, 25°C—but can easily be converted to Fahrenheit using the onboard dip switch located within the probe housing. To make this change:

• Twist and lift the probe’s protective plastic cover to access the main board.
• Locate the labeled temperature probe dip switch.
• Switch 5 to the ON position.
• Switch 6 to the OFF position.
• Allow the unit a moment to update the display.

Once configured, the display will automatically convert the reading—for instance, from 25°C to 77°F. After adjustment, simply replace the cover to protect the internal components.

From a hardware standpoint, this model is engineered for durability and visibility in demanding environments. Key construction and performance features include:

• 14-gauge aluminum enclosure
• Black powder-coated finish that is fingerprint and dust resistant
• Four-inch high display digits
• Visibility range up to 200 feet
• Four-digit display format
• Measurement range:
  • -50°C to 90°C
  • -58°F to 194°F
• 0.05° resolution for precise temperature readings
• 120 VAC power wall adapter
• Rear teardrop knockouts for 4×4 or 2×4 electrical rough-in box mounting

The included electronic probe features pleated wiring extending 25 feet, allowing flexible placement within the monitored area. It can be wall-mounted to ensure accurate environmental sampling exactly where temperature tracking is most important.

For operations like those at McCall Farms, the goal is straightforward: maintain optimal storage conditions for fruits and vegetables while giving staff a clear, immediate visual confirmation of room temperature. The DC-40-Temperature Fruit and Vegetable Room Display delivers that capability with durability, precision, and ease of use.
