Digital Fridge Thermometer
Large LCD Display: Features bold, oversized digits that allow you to check the temperature at a glance without even opening the fridge door (if placed near a window).
Min/Max Memory Function: Automatically records and stores the highest and lowest temperatures reached since the last reset. This is vital for identifying if a cooling unit failed overnight or during a power outage.

Quick Answer: A digital fridge thermometer is a thermometer with an electronic display, used to check the temperature inside a refrigerator or freezer holding reagents, samples, culture media, medicines or food. The title gives the type; the display, probe arrangement and range are confirmed on request.
Knowing the Real Temperature Inside a Refrigerator
A refrigerator’s dial or built-in display shows the setting or the air near its own sensor, which is not always the temperature where the samples sit. Air warms each time the door opens, door shelves run warmer than the back, and items against the cooling plate can freeze. An independent digital fridge thermometer placed among the stored items shows what they actually experience.
Designs vary. Some units sit wholly inside the fridge; others keep the display outside with a thin probe cable passed through the door seal, so the temperature can be read without opening the door. Many record the highest and lowest temperatures since they were last reset, which is how a warm spell overnight or over a weekend is detected. Which of these features this model has should be confirmed before ordering.
For stable readings, place the sensor on a middle shelf among the stock, not in the door or against the back wall. Some laboratories put the probe in a small bottle of liquid, such as glycerol solution, so that brief air swings from door openings are damped and the reading follows the temperature of the stored items.

Applications
- Daily temperature checks of reagent, media and sample refrigerators
- Monitoring pharmacy and vaccine fridges against the limits set for their contents
- Checking food storage refrigerators in food science and catering labs
- Spotting overnight or weekend temperature failures with max/min memory
Care & Handling
- Record the reading at the same times each day and reset the max/min memory after recording, if the unit has one.
- Route any probe cable through the door seal so it is not crushed or kinked.
- Replace the battery at the first low-battery sign; a blank display means a lost record.
- Check the digital fridge thermometer against a reference thermometer now and then.
Why Choose LabEquip
Laboratories, pharmacies, clinics and food businesses that must show their refrigerators stayed in range buy an independent thermometer for each unit. LabEquip lists this one in its General Lab Products range, with the non-digital pocket refrigerator thermometer as an alternative; contact LabEquip with the number of fridges to be monitored.
Frequently Asked Questions
Why use a separate thermometer when the fridge has a display?
The fridge’s own display reflects its control sensor or setting, not necessarily the temperature where your stock sits. An independent thermometer on the shelf shows what the stored items actually experience.
Where should the thermometer be placed?
On a middle shelf among the stored items, away from the door, the cooling plate and the back wall. The door is the warmest place and the back wall can be the coldest.
What is the max/min memory for?
It records the highest and lowest temperatures since the last reset. Checking it each morning shows whether the fridge went out of range overnight, even if the current reading looks normal.
Why put the probe in a bottle of liquid?
A probe in liquid responds slowly, like the stored samples themselves, so brief rises from opening the door do not trigger false alarms. The reading then reflects the temperature of the contents rather than the air.
Can it be used in a freezer?
Only if its range extends low enough and its display works in the cold. Units with an external display and probe cable are usually preferred for freezers. Confirm the range at enquiry.
How do I check the thermometer is reading correctly?
Place the probe in a mixture of crushed ice and a little water, stirred, and wait for the reading to settle. It should read close to 0 °C; a larger difference means the thermometer needs replacing or adjustment.
