Widely applicable to refrigerators, air conditioners, freezers, fish tanks, incubators, aquariums, and greenhouses. Ideal for home, office, car, etc.

The machine has a luxurious and elegant appearance, yet is small and compact. It is particularly suitable for measuring the temperature of electrical refrigeration products such as refrigerators, air conditioners, and cold storage units.

Temperature measurement and time display in various settings such as home, office, car, etc. It has a wide range of applications, simple and practical operation, and an intuitive and clear display. It features the following:

Dual temperature probes can detect two temperatures simultaneously.

Equipped with a clock display.

Celsius to Fahrenheit conversion.

High precision and intuitive display.

Time display range: 1:00-12:59

Temperature range: -50°C (-58°F) to +70°C (158°F)

Accuracy: ±1°C

Resolution: >-20°C corresponds to 0.1°C, ≤-20°C corresponds to 1.0°C

Instructions:

1. Open the battery cover on the body and install the battery. Do not install it upside down.

2. FSW is the function conversion key. When displaying the indoor temperature, "IN" is displayed simultaneously, and when displaying the outdoor temperature, "OUT" is displayed simultaneously. 3. Upon startup, the LCD screen will display the full display for 2 seconds, then display the current indoor temperature. During the 2-second full display, the function key will not change state. 4. If you press and hold the FSW function key for more than 4 seconds, it will turn off. However, the clock will continue to count down. 5. During measurement, if the temperature is greater than or equal to 70°C (158°F), the LCD screen will display H°C (°F) to the first decimal place; if the temperature is less than -50°C (-58°F), the LCD screen will display H°C (°F) to the first decimal place. The digit will then display L°C (°F).

6. If the battery is insufficient, the LCD screen will flash at a rate of 1 Hz and the battery must be replaced if the measurement is not permitted.

6. (°C/°F) is the Celsius/Fahrenheit switch, which can be selected depending on the brand.

7. Setting the time:

①First press the FSW button to switch the LCD screen to the time display.

②Setting the hour (HR button): Press once to increase by 1 hour; if it exceeds 12, it will continue counting from 1.

③Setting the minutes (MIN button): Press once to increase by 1 minute; if it exceeds 59, it will continue counting from 00. 8. A built-in sensor probe can measure the temperature around the body (inside). 9. Place the sensor probe outside the machine. Position the probe where the temperature needs to be measured, and the temperature value can be displayed on the LCD screen.
