Comark KM400AP Allergen Pocket Digital Thermometer, Range -50°C to +200°C

The KM400AP Waterproof Allergen Thermometer is colour-coded for food allergy procedures and features a thin tip for fast response times.

The pen-style Comark KM400AP Waterproof Allergen Thermometer is purple, the agreed colour in the food service industry for kitchens to identify allergen-free food items.

If your kitchen regularly handles milk, eggs, fish, peanuts, tree nuts (walnuts, almonds), wheat, soybeans, and shellfish (shrimp, crab), or other food allergens, preventing cross-contamination is becoming more and more important. HACCP plans now detail separating foods or ingredients which may cause allergies and also using separate utensils for different foods.

The KM400AP Waterproof Allergen Thermometer has a 1.5mm thin tip for a fast response together with a hold feature on the thermometer which enables the user to temporarily fix the reading the screen while they note a measurement.

Field Calibration Procedures

1. The KM400AP is only calibratable in a slush ice solution (60% crushed ice and 40% tap water) or a water bath. Do not attempt to calibrate in any other manner
2. Immerse the stem of the thermometer to at least 1/2 length in the slush ice solution
3. Wait for the reading to become stable (usually ±1° of 0°C / ±2° of +32°F)
4. Press and hold the D-H button for 8 seconds to begin calibration
5. CAL will be displayed for two seconds and calibration at 0°C / +32°F is completed
6. Remove the thermometer from the ice water and continue to take measurements
7. Note: CAL will be displayed any time the D-H key is pressed for 8 seconds, but the thermometer will not be re-calibrated unless the tip is inserted in ice water
