12207 Min/Max and 12213, 12215 Certified Min/Max Alarm Thermometers FAQs
Can I calibrate my 12207 Min/Max Alarm Digital Thermometer?
No. The product is not user-calibratable. The external probe can have the calibration verified at 0.0°C using crushed ice and water.
Why is the temperature not changing on my thermometer or the display is flashing?
The thermometer is in “Min/Max” or ”Alarm Set” mode. If the display is flashing press the “Alarm Set“ button until it stops flashing. If “Min” or “Max” is showing press the “Min/Max” button until neither show. It should now display the temperature.
Can I calibrate my 12213 or 12215 Certified Alarm Thermometer?
No. The product is not user-calibratable but comes with a NIST traceable Certificate of Calibration good for 1 year from the date of purchase.
Can I verify the calibration on my 12213, 12215 glycol bottle thermometers myself?
It is possible but without a circulating ice water bath it is difficult to maintain the stable temperature long enough due to the slower response time of the glycol bottle. In cases where the accuracy is in question it can be tested following the DeltaTrak approved procedure. It is better to purchase a new unit with a Certificate of Calibration if the product was purchased more than 1 year ago.
Should I send in my 12213 or 12215 Certified Alarm Thermometer for calibration each year?
No. It is better to purchase a new thermometer with a Certificate of Calibration and full year warranty for about the same cost as a calibration.
After 30 minutes of putting the glycol bottle from my 12213 or 12215 Certified Alarm Thermometer in my refrigerator is the temperature reading still above the actual refrigerator temperature?
The glycol bottle is designed for slower thermal response time so the temperature readings do not spike up when the door is opened and warm air enters. It can take an hour or 2 before the glycol in the bottle reaches the same temperature as the air in the refrigerator.
The temperature is reading way off on my 12213 or 12215 Certified Alarm Thermometer when the glycol bottle is in the refrigerator or freezer?
The thermometer is set to "In” (12213) or “Int” (12215) Internal Sensor and should be set to “Out” (12213) or “Ext” (12215) - the external sensor in the glycol bottle. Press the “Int/Ext” button until the display reads “Out” or “Ext”.
The alarm is not working on my thermometer?
Either the alarm is turned-off or the external sensor temperature is within the set alarm limits in the thermometer. Press the "Alarm Set" and verify the alarms are correct. Press the “Alarm Set” button until the display shows “AL” in the lower left corner.
Will the alarm settings work for the Internal Sensor also?
No. The alarms are only for the External Sensor.
Will the alarms drain the battery if the alarm is sounding too long?
Yes. Depending on the charge of the battery if the thermometer is in alarm for many hours the battery will eventually die and the unit stop working.
