How often do you need to calibrate (check) your Thermoprobe (Also referred to as PET)?

ICL is a factory authorized representative, service, parts and calibration facility. We stock all parts for all current ThermoProbe models and can repair and re-calibrate (with new certificate) all models quickly, professionally and at competitive rates.

We have “loaner” ThermoProbes available for emergency situations. Call us by 4:00 pm Eastern time and you’ll have a loaner the next morning! There is no charge for the “loaner” service, except for shipping. Just send us back the “loaner” when you get your repaired ThermoProbe back from us.

7.8.2 Initial Calibration

Before initial use, and at least once a year thereafter, each portable electronic thermometer shall be re-standardized in a laboratory or other qualified calibration facility. The thermometer shall be re-standardized by comparing it at three or more temperatures with either a National Bureau of Standards (NBS) (ICL note: NBS is now NIST) certified thermometer or an equivalent thermometer with accuracy traceable to the NBS in accordance with the manufacturer’s instructions. These standardization checks will ensure that accuracy is maintained within the limits given in Table 3.

8.2.1 Field verification

Before each use, or once per day (whichever is less frequent), portable electronic thermometers should be spot checked by comparing the ambient reading against an ASTM glass stem thermometer in liquid. If the readings differ by more than 0.5 degree F (or 0.25 degree C), the portable electronic thermometer should be re-standardized before it is used for custody transfer.

8.2.2 Monthly Verification and Inspection

On a monthly schedule, the portable electronic thermometer should be checked at two or more temperatures near the ends of its range against an NIST certified thermometer or an equivalent thermometer with accuracy traceable to the NIST. Make this check by placing the two thermometers side-by-side in a circulating bath and leaving them undisturbed for at least 10 minutes before making comparative readings. Alternately, the ice point and boiling point of fresh water may be used for accuracy check. The boiling point of fresh water must be corrected for altitude. If the thermometer readings differ by more than the tolerances listed in Table 1, the thermometer should be re-standardized (see 7.8.2)

In addition, the following physical checks should be made:

  1. The junction between the cable and the probe should be checked for mechanical damage.
  2. The cable insulation should be checked for cuts, breaks, or abrasion.

ICL Calibration Laboratories can perform this calibration and certification for you with a one to two day turnaround.
