The PosiTest OTL arrives fully calibrated and ready to measure. A Long-Form Certificate of Calibration traceable to NIST is included, which documents actual readings taken by your instrument at our calibration laboratory on standards traceable to a national metrology institute. Beware of ‘Certificates’ or ‘Certificates of Conformance’ offered by competitors. These typically do not include actual instrument readings, and are often insufficient to meet common quality requirements.
The PosiTest OTL and K-type thermocouple Temperature Probes are calibrated at the factory — with no expiry or end date. They have no shelf life; therefore the length of time in use is not a good indicator for recalibration intervals.
Many organizations with quality programs and recertification programs require annual recalibrations, and this is a good starting point for most users. DeFelsko recommends that customers establish calibration intervals based upon their own experience and work environment. Based on our product knowledge, data, and customer feedback, a one year calibration interval from the date the instrument was placed in service is a good starting point.
No. Due to the lengthy calibration process, it is more economical for the PosiTest OTL temperature probes to be replaced if required.
The PosiTest OTL is available in two configurations. The PosiTest OTL XT Kit features an enhanced holder with heatsink for greater endurance at high temperatures.
A wide variety of spring clamp and magnetic temperature probes are available with either 1.8, 3.6, or 6 m (6’, 12’, or 20') stainless steel braided cables for testing air or surface temperatures. Each temperature probe includes a Certificate of Calibration traceable to NIST.
A wide variety of temperature probes are available with 1.8, 3.6, or 6 m (6', 12', or 20') stainless steel braided cables (sold separately).

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.
A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!
Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
Stated accuracy of Td is ±3C for Td from -40 to 80C.
