DFP450W

A Digital Pocket Test That

Measures Dishwasher

Final Rinse Temperature

The DFP450W was specifically designed for the harshest foodservice environments. Potentially hazardous

mercury thermometers are often used to check the extreme temperature and water soluble conditions of

commercial dishwater. Eliminate the risk of a mercury spill; the

DFP450W maintains the heat and resists the

water of Commercial 2-Cycle dishwashers.

Do not be alarmed if the DFP450W display is blacked out when you remove it from the

dishwasher - this is normal. In the dish washing process, high heat shocks the display

but the electronics still record the maximum temperature. Once cooled, the display

will return to normal. Reset and you are ready for the next cycle.

The DFP450W is a digital pocket test thermometer specifically designed for measuring the final rinse temperature in commercial dishwashers, making it ideal for foodservice environments. This device offers a safe and accurate alternative to traditional mercury thermometers, eliminating the risk of mercury spills in food preparation areas.

Function Description

The primary function of the DFP450W is to accurately measure and record temperatures, particularly the maximum temperature reached during a dishwasher cycle. It is designed to withstand the harsh conditions of commercial dishwashers, including high heat and water exposure. The unit features a "MAX" button to display the highest temperature recorded, which is crucial for ensuring dishwashers meet sanitization standards. Even if the display temporarily blacks out due to extreme heat during a dishwasher cycle, the internal electronics continue to record the maximum temperature, and the display returns to normal once cooled.

Important Technical Specifications

Temperature Range: -40° to 450°F (-40° to 232°C)
Accuracy: ±2°F (±1°C)
Resolution: 0.1°
Display: 0.25" / 6.4 mm High LCD Display
Stem Length: 5" / 27 mm
Sensor Type: Thermistor sensor located in the probe tip
Power Source: 1.5 Volt Battery
Certifications: NSF certified

Usage Features

ON/OFF Control: The unit is turned on and off by pressing the "ON/OFF" button. It features an auto shut-off function after 10 minutes of non-use to conserve battery life.
Maximum Temperature Memory: Pressing the "MAX" button displays the highest temperature recorded. This feature is particularly useful for applications where extreme temperatures are reached, such as in freezers and dishwashers. The unit retains the maximum temperature reading even after it shuts off. To clear the "MAX" reading, press and hold the "MAX" button for 3 seconds while in "MAX" mode; the unit will then revert to displaying the current temperature.
Quick Response Time: The thermistor sensor in the probe tip ensures quick response times and accurate readings, which is essential for efficient temperature monitoring.
Field Calibration: The DFP450W can be field calibrated to maintain accuracy. The calibration process involves immersing the stem at least 1 inch into a slush mix (finely crushed ice and water) without touching the container's sides or bottom. For recalibration, the thermometer must register within the temperature range of 23°F (-5°C) to 41°F (5°C). To enter calibration mode, press and hold the "ON/OFF" button for 8 seconds until "CAL" is displayed on the LCD. Once the display stabilizes, press the "CAL" button until the display reads 32°F (0°C). The unit is then calibrated and ready for use.
Durability: Designed to withstand the heat and water of commercial 2-cycle dishwashers, making it suitable for demanding foodservice environments.

Maintenance Features

Cleaning: Stubborn grease can be removed from the stem using a scouring pad or fine steel wool.
Lifetime Warranty: The DFP450W comes with a lifetime warranty, indicating the manufacturer's confidence in its durability and reliability.

The DFP450W is a robust and reliable tool for ensuring food safety by accurately monitoring critical temperatures in commercial dishwashers, providing peace of mind for foodservice professionals.
