*Most accurate temperature tester in the world boasts ±0.2°C (±0.5°F) accuracy

The Checktemp® is a digital thermometer featuring a stainless steel penetration probe. It delivers high accuracy temperature measurements over a wide temperature range without worrying about breakage or condensation.

With the Checktemp®, users won't need to worry about breakage, waste, injuries, or difficulty interpreting results; the digital display prevents a parallax error (observing the wrong measurement due to the angle of view) and is optimized for a wide range of environmental temperatures. Checktemp® is provided with Hanna’s unique CAL Check™ function for accurate measurements every time. The Checktemp® implements a CAL Check™ upon startup and reports the status as 0 or Err.

The sharp tipped stainless probe of the Checktemp® easily penetrates semi-solid products making routine temperature checks simple and quick for both incoming and outgoing goods. Checktemp® is the ideal instrument for measuring temperature according to HACCP requirements, and is great for use with semi-solid foods, liquids, and laboratory purposes.
