The 1441 Taylor Digital Waterproof Thermometer is a highly accurate instrument with dual channels for two separate and independent temperature measurements. Temperatures are measured and reported by two sensor probes, each on its own 9-foot 9-inch (3-meter) cable. This thermometer has a weather resistant housing for indoor or outdoor use. Temperatures can be displayed in °F or °C. The 1441's memory stores, and allows you to display, the maximum and minimum temperatures for the current 24-hour period and the past six 24-hour periods for each of its two channels. The 1441 is a high-quality instrument that is suitable for a variety of industrial and institutional applications, including manufacturing, food service (food storage), and medical (drug storage) facilities. Naturally, it can be used in homes and offices as well.

The measuring range of the Taylor 1441 thermometer is -40°F to +120°F or -40°C to +50°C in 0.1° increments. The operating temperature range for the thermometer body is -4°F to +120°F or -20°C to +50°C. You select °F or °C by pressing a button in the battery compartment on the back of the thermometer body.

Under the hinged cover on the front of the 1441 are three control pushbuttons for each sensor probe. To view the current temperature for a particular sensor probe, you simply press its ON button. Pressing MAX once shows the highest temperature recorded during the current 24-hour period. Pressing MAX six more times displays the maximum recorded temperatures for the past six 24-hour periods, which are indicated by D.1 through D.6 in the display. Similarly, pressing MIN once shows the lowest temperature recorded during the current 24-hour period. Pressing MIN six more times displays the minimum recorded temperatures for the past six 24-hour periods, which are again indicated by D.1 through D.6 in the display. Pressing MAX or MIN after the D.6 reading is displayed returns the display to the current temperature. The oldest (D.6) maximum and minimum readings are automatically dropped each day, and the minimum and maximum temperatures for each period move from D.1 to D.2, D.2 to D.3, etc.

In addition to the six control pushbuttons under the front cover is a small, recessed memory reset pushbutton. You can press it to reboot the 1441's microprocessor and sequence the start time of the min/max recording periods.

The temperature displays automatically turn off 10 minutes after being turned on. However, the 1441's advanced microprocessor circuit continues to record temperature data when the displays are off. This maximizes battery life because the displays are on only for the time needed to read the temperature and recall min/max data.

For powering, the 1441 requires one AA (1.5V) battery, which is not included and must be obtained separately. We recommend using an alkaline battery unless the thermometer body will be located where temperatures remain below freezing for extended periods. In this case, install a lithium battery instead of an alkaline battery. A low-battery indicator in the display tells you when replacement is necessary. When replacing the battery, be sure to replace the battery compartment cover correctly with its gasket in place to maintain watertight integrity.

As mentioned above, the Taylor 1441 is designed for indoor or outdoor use. On the back of the case at the top and bottom are two flanges for attaching the 1441 a wall or other vertical surface. You'll need to supply the screws for doing this.

For more than 150 years, Taylor measurement products have been the professional's choice for accuracy, readability, and durability, and the 1441 is no exception. With functional, no-nonsense styling and precision craftsmanship, the Taylor 1441 Digital Waterproof Maximum/Minimum Thermometer an excellent choice when accurate temperature measurement via probe is required at two separate locations in close proximity to one another. The 1441 is covered by a Taylor 1-year limited warranty.
