Thermometers are essential medical devices used to measure body temperature. Various types serve different clinical needs, including simple glass thermometers, oval clinical thermometers, infrared forehead thermometers for non-contact use, and digital non-flexible thermometers offering quick and accurate readings.

•  Glass for simple and oval clinical thermometers

•   Plastic housing and electronic sensors for infrared and digital thermometers

 •  Medical Diagnostic Instruments

•  Thermometers

•  Simple & oval: glass tube with temperature scale

•  Infrared: handheld device with sensor and digital display

•  Digital non-flexible: handheld with electronic sensor and digital display

•  Measuring body temperature orally, rectally, axillary, or via forehead (infrared)

•  Used in clinics, hospitals, and home care for fever monitoring and diagnosis

•  Simple and oval: reliable, no batteries required

•  Infrared: non-contact, hygienic, fast results

•  Digital: quick, easy-to-read, accurate

•  Multiple options for different clinical needs

•  Glass thermometers fragile and can contain mercury (environmental concern)

•  Infrared devices may require calibration

•  Digital thermometers require batteries

•  Non-flexible digital thermometers less comfortable for some users

•  Handle glass thermometers carefully to avoid breakage

•  Keep digital and infrared thermometers clean and sanitized

•  Follow manufacturer instructions for accurate readings

•  Replace batteries in digital devices timely

•  HS Code: 9025.19 (Instruments for measuring temperature)

•  HSN Code: 9025.19.90

•  For glass thermometers, shake before use to reset

•  Place appropriately depending on type (oral, rectal, axillary, forehead)

•  Clean after every use with alcohol wipes/ Store in protective case or dry place

 •  Clean with 70% isopropyl alcohol or disinfectant wipes after each use

 •  Avoid immersing digital/infrared thermometers in liquids

Veterinary Application

•  Simple and digital thermometers are often used for measuring animal body temperature

•  Infrared thermometers are preferred for non-contact temperature checks in sensitive or aggressive animals

Human Application

•  All types are widely used for human clinical temperature monitoring in hospitals and homes

•  Infrared thermometers gained popularity for quick, non-invasive screening especially during pandemics

Q1: What is the best thermometer for quick readings?

Infrared and digital thermometers.

Q2: Are glass thermometers safe?

They are safe if handled carefully but may contain mercury which is hazardous if broken.

Q3: Can infrared thermometers be used on animals?

Yes, for non-contact temperature readings.

Q4: How often should digital thermometer batteries be changed?

Typically every 6-12 months or as needed.

Q5: How to clean thermometers?

With 70% isopropyl alcohol or disinfectant wipes.
