Thermometer KAISER Precision Thermometer model 4086 — body 10–50 °C, accuracy ±2 °C

KAISER Precision Thermometer model 4086 is a compact alcohol-filled clinical thermometer for measuring human body temperature. The instrument features a luminous blue capillary and a clear glass scale from 10 to 50 °C with 0.2 °C graduations, providing quick single-point readings. With a reported accuracy of ±2 °C for body measurements and a maximum immersion depth of 60 mm, this thermometer is intended for basic temperature checks at home, in clinics, or in field situations where simple, portable monitoring is needed.

Advantages

The thermometer’s alcohol-filled bulb and luminous blue capillary ensure visible readings in varied lighting conditions. Its compact glass tube and fine 0.2 °C calibration steps make it easy to read single-point values, while the maximum immersion depth of 60 mm supports safe use for oral or auxiliary measurements. The design focuses on portability and straightforward operation without reliance on batteries or electronics.

Suitable for

• Basic body temperature checks at home
• Primary care clinics and screening stations
• Field use where a simple, non-electronic thermometer is preferred
• Situations requiring a compact, battery-free temperature measurement

How to use

Before use, ensure the thermometer is clean and the alcohol column is below the normal body temperature mark. For oral measurement, place the bulb under the tongue and close the mouth for the recommended time indicated by local clinical guidance. For auxiliary measurement, place the bulb in the armpit with the arm held firmly against the body. After reading, return the thermometer to a level position and note the value indicated on the glass scale. Clean the bulb and stem with an appropriate disinfectant or alcohol wipe before and after each use and store the thermometer in a protective case to avoid breakage.

Usage recommendations

Use the thermometer only as intended for basic body temperature checks. Handle the glass instrument carefully to avoid breakage. Do not attempt to repair a damaged glass thermometer; replace it if the glass is cracked or the filling is lost. For clinically critical measurements or when higher accuracy is required, consider using a medical thermometer with certified clinical accuracy.
