Waterproof portable thermistor thermometer for brewing - HI935012


In stock

HI935012 is a waterproof portable thermistor thermometer designed for brewing industry. The HI935012 is supplied with the FC762N2 stainless steel probe that is 1 meter in length and is used to measure the temperature of mash in the center of a tank. This meter can be used at other critical points of the brewing process including the wort boil and fermentation.

  • CAL Check to ensure internal electronics are within acceptable tolerances
  • Probe Error Messages
  • High accuracy ±0.1℃/±0.2℉


The HI935012 is a waterproof portable thermistor thermometer made for the brewing professional that needs to measure the temperature in the center of a tank or vessel. The HI935012 is supplied with the FC762N2 thermistor probe that is made of stainless steel and is 1-meter long. For a fast and accurate measurement, the pre-calibrated semi-conductor sensor is located in the tip of the probe.

The HI935012, as a meter, can measure over a wide range of temperatures from -50.0 ℃ (-58.0 ℉) up to 150 ℃ (302 ℉) and offers a very high accuracy of ±0.1 ℃ (±0.2 ℉). The accuracy of the meter is assured with advanced diagnostic features including CAL-Check that checks for an abnormal drift of the internal electronics. Using a properly prepared ice bath, the meter and probe can be calibrated by the user. Additional features to have confidence in the measurements include a battery error prevention system (BEPS) that will not allow a reading to be taken when there is not sufficient battery power and probe diagnostics that alert the user when the probe is not connected

There are many considerations when designing a thermometer for the food professional. Below are features that we considered to be important and beneficial.

CAL Check

The calibration check (CAL Check) feature of the HI935012 is an internal diagnostic feature that checks for any drift in the electronics that occurs with all digital thermometers over time. When the meter is turned CAL Check looks to see if the internal calibration is within ±0.3 ℃. If the drift is greater and error (err) message will be displayed. With CAL Check you can be confident that the meter is working properly

Long Battery Life

The thermometer has an exceptional battery life of approximately 4500 hours using three common AAA batteries. The battery percent level is displayed when powered on alerting the user to the remaining battery life

Probe Error Messages

The “NO PROBE” message is displayed on the meter when a probe is not attached or there is a break in the cable

1M Stainless Steel Probe

The supplied FC762N2 thermistor probe that is 1 M (39″) long and 10 mm (0.39″) in diameter. This extra-long probe allows for the measurement of temperature in the middle of tank to make sure it is consistent throughout.

Supplied with Carrying Case

The HI935102 is supplied with a soft carrying case that holds both the probe and the meter. There is a pouch inside for easy access to the meter.

Supplied with Instrument Quality Certificate

HI935012 with the FC762N2 are calibrated according to an ISO9001 calibration system using standards and reference instruments in which the accuracy is traceable the National Institute of Standards (NIST) in the USA, or to internationally acceptable physical standards

Additional Features/Benefits:

Large LCD

  • An enhanced LCD displays the measurement reading in ℃ or ℉, stability indicator, error messages, and low battery indicator.

Stability Indicator

  • An hourglass indicator is displayed on the LCD until a stable reading is obtained. Once a reading stabilizes, the indicator disappears and a reading can be taken.

Automatic Shut-off

  • The meter can be set to automatically turn off after 8 minutes or 60 minutes to conserve battery life in the event that the meter is left on. The auto-off feature can also be disabled.

Ergonomic, rugged, waterproof (IP65) design

  • For additional protection the HI710027 shockproof rubber boot is available as an accessory.
