Hanna Checktemp® Digital Thermometer

The Checktemp® Digital Thermometer HI98501 is a digital thermometer with stainless steel penetration probe.

It delivers high accuracy temperature measurements over a wide temperature range without worrying about breakage or condensation.

• CAL Check™
• ℃/℉ readout

The Checktemp® offers NO breakage, NO waste, NO injuries and NO difficulty in reading; 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-tip 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.

Q&A

How accurate is the Checktemp digital thermometer?

The thermometer offers high accuracy of approximately ±0.2 °C (±0.5 °F) within the core working range, ensuring reliable readings for most professional and industrial applications.

What temperature range can it measure?

It measures temperatures from about −50.0 °C to 150.0 °C (−58.0 °F to 302.0 °F), covering most common needs from freezing to high‑temperature conditions.

What is the CAL Check™ function?

The built‑in CAL Check™ automatically verifies the thermometer’s calibration every time it is turned on. It displays a status of “0” if calibration is correct or “Err” if there’s a problem, helping users trust each measurement. 

Is the thermometer durable and suitable for daily use?

Yes. The unit is water‑resistant with an IP65 rating, has a large easy‑to‑read display, and uses an AISI 316 stainless‑steel probe, making it tough enough for daily professional or field use. 

How long does the battery last?

The thermometer runs on a small coin cell battery (CR2032) and can last up to approximately 3000 hours of continuous use, reducing the need for frequent battery changes. Can the Checktemp thermometer be used in food safety programs?

Yes. It is HACCP compatible and suitable for monitoring temperature as part of food safety and quality control procedures in processing, storage, and transport environments.

How easy is it to use?

The Checktemp thermometer is simple and intuitive: turn it on and it begins measuring. It also allows users to switch between °C and °F, and includes an automatic shut‑off feature to save battery when not in use.
