The meter is specifically designed for measuring the temperature in many chemical processes that take place during the beer production including mashing, wort separation, fermentation and finally packaging, distribution and aging. Both air temperature and product internal temperature can be measured with this thermometer. The dedicated probe FC762N2 shaft is designed for continuous contact with foodstuffs in accordance with Regulation (EC) 1935/2004.

Temperature plays a central function in brewing operations. Spot checking temperature throughout the process ensures daily work routines are carried out at the correct temperature, and equipment is operating efficiently. Temperature measurements are made at the hot water tank, the mash tank, the boil kettle, fermenter, bright beer tank and final storage area. Temperature checks provide peace of mind the operation is running smoothly and the batch will be uncompromised.

CAL Check™ function

Hanna's brew thermometer includes our exclusive CAL Check™ technology. CAL Check™ ensures that your meter is working optimally so you can be confident in all your results.

Long battery life

The included AAA batteries provide 4500 hours of continuous use. When the battery level is below 10%, a warning symbol flashes to indicate that the battery is low. If a low battery will affect your results, the meter will shut off to prevent false readings caused by a low battery level.

Automatic shutdown

The auto-shutoff feature extends the life of the battery for peace of mind and energy savings if the meter is accidentally left on. The auto shut-off feature can be set to turn off the meter at 8 or 60 minutes, or it can be disabled so that the meter remains on continuously.

Portable design

Hanna's brew thermometer was designed to fit comfortably in your hand for testing on the go. A large LCD display provides at-a-glance readings from any angle, and one-button operation streamlines the testing process for any brewer.

Built to be durable

Designed to withstand real-life shocks, drops and spills, the IP65 body and included boot offer added protection for a durable thermometer that can handle any brewing environment. These meters are well protected against dust and water spray from all directions.

Waterproof connection

A Quick DIN connector makes attaching and removing the probe simple and easy. The rubber coating protects the cable and creates a tight connection for increased reliability.

Supplied with a 1 m stainless steel temperature probe

The FC762N2 temperature probe is a rugged penetration probe measuring 1 meter in length. The stainless steel probe is both durable and easy to clean, the perfect combination to meet the harsh environment encountered in breweries. Each probe is extra long so you can reach deeper into your tanks without compromising safety or accuracy.

Completely interchangeable probes

Hanna's brew thermometer works with a wide range of thermistor probes, including an assortment of specially designed FC762 probes, so you can get the right probe for your brewery.  

Technical Q&A

What is a portable thermistor thermometer used for in beer brewing?

A portable thermistor thermometer is used to measure temperature during different stages of the brewing process. Accurate temperature monitoring is important during steps such as mashing, wort boiling, fermentation, and storage, as these processes depend on maintaining specific temperature ranges for proper enzyme activity and yeast performance. 

How does a thermistor thermometer measure temperature?

A thermistor thermometer measures temperature using a semiconductor sensor whose electrical resistance changes with temperature. The instrument converts this resistance change into a digital temperature reading, allowing for fast and highly sensitive measurements suitable for laboratory and food-processing applications.

Why is temperature control important in brewing?

Temperature plays a critical role in brewing because it influences enzyme reactions during mashing, sugar extraction, yeast activity during fermentation, and overall flavor development. Monitoring temperature throughout the brewing process helps ensure consistent product quality and efficient operation of brewing equipment.

What temperature range can a brewing thermistor thermometer typically measure?

Portable brewing thermometers commonly measure temperatures in a range of approximately −20 °C to 120 °C (−4 °F to 248 °F), which covers typical brewing processes from cold storage and fermentation to hot mash and boiling stages.

How accurate are thermistor thermometers used in brewing?

High-quality portable thermistor thermometers can achieve measurement accuracy of around ±0.1 °C for the meter and approximately ±0.3 °C for the probe within common brewing temperature ranges. This level of precision allows brewers to maintain consistent mash temperatures and fermentation conditions. 

What type of probe is commonly used with brewing thermometers?

Brewing thermometers are often equipped with a stainless-steel penetration probe designed for direct contact with liquids and food products. Long probes, typically about 1 meter in length, allow the user to safely measure temperatures deep inside mash tuns, kettles, and fermentation tanks. 

Are portable brewing thermometers designed for harsh environments?

Yes. Many brewing thermometers are designed with rugged housings and water-resistant or splash-resistant protection (such as IP65 or IP67 ratings) to withstand the demanding conditions found in breweries, including moisture, spills, and frequent cleaning. 

What features improve usability in a portable brewing thermometer?

Common features include a large LCD display, interchangeable probes, automatic power-off to conserve battery life, diagnostic functions to verify instrument performance, and durable connectors for quick probe attachment. These features help brewers obtain reliable temperature readings during daily operations. 

Application Q&A

When is data logging especially valuable?

Logging is valuable when trends matter more than a single spot reading, such as curing history, storage conditions, verification records, or alarm-driven incident response.

Who is this best suited for?

Food processors, kitchens, breweries, and qa teams will get the most value when they need repeatable measurements plus a record they can review, export, or act on later.

Because it combines 1m Stainless Steel Thermistor Temperature Probe (FC762N2), Calibration Check feature, User calibration at 0 °C, this product is a strong fit for food-process temperature checks and recorded verification where documentation and repeatability are important.
