Digital fridge/freezer thermometer
Description
The Digital Fridge/Freezer Thermometer - Min/Max (SKU DT210) is a compact max/min digital alarm thermometer designed for reliable monitoring of refrigerator and freezer temperatures, ideal for clinical cold chain applications. The unit features a large, easy-to-read LCD display and two temperature sensors: an internal sensor for ambient (room) temperature and a remote water-resistant probe with a PVC lead for measuring appliance temperature inside the fridge or freezer. It measures temperatures over a wide range from approximately -49.9°C to +69.9°C with 0.1°C/°F resolution and typical accuracy of ±1°C. A max/min memory function records highest and lowest temperatures, and a programmable audible alarm alerts users when temperatures move outside preset limits, supporting proper storage of temperature-sensitive medical products. The thermometer is housed in a robust ABS plastic case with integrated foot-stand for shelf mounting and is supplied with mounting accessories for the remote probe.
Bnefits
- Provides continuous, accurate monitoring of fridge and freezer temperatures to help maintain cold chain compliance for medicines, vaccines and other temperature-sensitive products.
- Wide measurement range (approximately -49.9°C to +69.9°C) covers typical clinical refrigerators and freezers.
- Max/min memory function records the highest and lowest temperatures, helping verify temperature excursions over a given time period.
- Programmable audible alarm alerts users if temperatures move outside set limits, supporting prompt corrective action.
- Dual-sensor design with internal ambient sensor and remote water-resistant probe (with around 1 m PVC lead) allows simultaneous monitoring of room and appliance temperatures.
- Large LCD display with 0.1°C/°F resolution provides clear, quick temperature readings.
- Compact, robust ABS case with foot-stand and mounting accessories (suction pad and bracket) enables flexible placement and easy viewing.
- Battery-powered (typically 1.5 V AAA cell) with long battery life (often quoted around 5000 hours), making it suitable for continuous use in clinics and pharmacies.
Indications
- Monitoring storage temperatures in clinical, pharmacy and aesthetic practice refrigerators and freezers used for medicines, vaccines and other temperature-sensitive products.
- Routine temperature logging in cosmetic and aesthetics clinics for compliance with cold chain standards.
- General monitoring of domestic or commercial fridges and freezers where precise temperature control is required.
- Use in medical, laboratory, catering and food-service environments where max/min and alarm functions are needed.
Composition
- Instrument housing: Robust ABS plastic case (approx. 15 x 52 x 73–75 mm).
- Display: Large LCD temperature display (typical digit height around 16 mm).
- Sensors: Two temperature sensors – internal sensor for room/ambient temperature and external water-resistant probe for appliance temperature.
- Probe lead: Approx. 1 metre PVC insulated cable for remote probe.
- Electronics: Digital temperature measurement circuit with max/min memory and alarm function.
- Power source: 1 x 1.5 V AAA battery (typical) supplying approximately 5000 hours of operation.
- Controls: Front or rear buttons for power, °C/°F selection, max/min recall and alarm settings.
- Mounting options: Integrated foot-stand for shelf use; suction pad and/or mounting bracket for probe attachment inside fridge/freezer.
Formulation
- Non-sterile electronic measuring device intended for environmental/appliance temperature monitoring.
- Digital thermometer with max/min memory and audible alarm functionality.
- Designed for repeated, long-term operation in typical indoor and refrigerated appliance environments within stated temperature and humidity ranges.
Packaging
- Supplied as a single digital fridge/freezer thermometer unit per pack.
- Typically includes: main thermometer unit with LCD display, remote water-resistant probe with PVC lead, suction pad and/or mounting bracket for probe, integrated foot-stand and user instructions.
- Battery (1 x AAA) may be supplied pre-installed or separately, depending on supplier packaging.
- Packaged in a protective retail carton or blister pack suitable for clinic or pharmacy storage and shipping.
Usage
- Install or check the AAA battery according to polarity markings, ensuring secure battery compartment closure.
- Place the main thermometer unit outside the fridge/freezer where the display can be easily viewed (e.g., on a worktop or shelf) using the integrated foot-stand or wall mounting if available.
- Route the probe lead carefully and place the remote water-resistant probe inside the fridge or freezer in a representative location away from direct contact with cooling vents, doors or interior lights.
- Secure the probe using the supplied suction pad or mounting bracket on an internal wall of the appliance to prevent it from being moved accidentally.
- Power on the device and select the desired temperature scale (°C or °F) using the appropriate button.
- Allow sufficient time for the probe and internal sensor to equilibrate before relying on readings.
- Set high and low alarm limits according to local cold chain or manufacturer guidelines for stored products, following the button sequence described in the user manual.
- Use the max/min function to review recorded highest and lowest temperatures over the monitoring period; reset max/min when starting a new logging interval as per local SOPs.
- Record temperatures and max/min values at the required frequency in a temperature log book or electronic system, following clinic or pharmacy protocols.
- Do not immerse the main unit in liquid; if the probe is water-resistant, only the probe tip may be exposed to moisture as specified by the manufacturer.
- Clean the outer surfaces of the main unit and probe with a lightly dampened cloth and mild detergent or appropriate disinfectant; avoid strong solvents and do not allow liquid to enter the case.
- Replace the battery when the display fades, low-battery indicator appears (if provided), or readings become unreliable.

Storage Conditions
- Store the thermometer in a cool, dry environment when not in use, away from direct sunlight and extremes of temperature.
- Avoid storing in locations with excessive humidity, condensation or risk of water ingress into the electronic housing.
- Protect from strong impacts, dropping or crushing forces that could damage the ABS case, LCD or internal electronics.
- Remove the battery for long periods of non-use to reduce the risk of battery leakage and internal corrosion.
