⚡ At a Glance
- • Measuring Accuracy: Accurate to +0.1 / -0.15°C across 35.5 to 42°C
- • Best for: Parents, carers and allergy sufferers needing reliable analogue readings
- • Not ideal for: Users who require instant digital readouts or memory logging
Analogue glass clinical thermometer with a calibrated scale for clinical ranges. Measurements cover 35.5 to 42°C with tight accuracy tolerances.
Safer temperature checks - thanks to a mercury-free liquid metal alloy
The measuring liquid is a gallium, indium and tin alloy that behaves like traditional mercury in a glass column but contains no mercury. No batteries are required because the expansion of the liquid in the glass indicates the temperature.
Safer handling and storage around children and pets, with the familiar glass-column readout used in clinical settings.
Trusted clinical accuracy - with a calibrated glass scale and narrow tolerance
Calibration ensures readings are accurate to +0.1 / -0.15°C within the 35.5–42°C range, suitable for fever detection. A reset tool is provided to return the measuring liquid to the start position between readings.
Consistent, clinically relevant readings make it straightforward to track temperature changes over time.
Hygienic, allergy-friendly handling - thanks to waterproof, nickel- and PVC-free construction
Glass construction is waterproof for washing and the materials are free from nickel and PVC, reducing contact allergens. The thermometer is supplied with a protective case to store between uses.
Simple cleaning and hypoallergenic materials reduce cross-contamination risk, suitable for oral, axillary or rectal use.
