Overview

Laboratory thermometers are precision tools used to measure temperature in experiments, sample preparation, and process control. Available as glass (mercury or alcohol), digital probe, infrared, and thermocouple types, they differ in range, response time and chemical resistance. Selecting the right thermometer means matching accuracy, range, probe type and durability to your application. Used units are common but should be inspected and calibrated before critical use.

FAQ

What should I consider when buying a used laboratory thermometer?

Check the type (digital, glass, thermocouple), specified accuracy and range, calibration history and certificates, probe condition, any signs of damage or contamination, and compatibility with the chemicals or sterilization methods you use.

How do I ensure the thermometer is shipped safely to my lab?

Pack probes and fragile glass in padded, rigid containers and secure moving parts. Declare any hazardous components (e.g., mercury), use a carrier experienced with lab equipment, insure the shipment, and include handling instructions to prevent shock or extreme temperature exposure.

What is the maintenance and calibration schedule for lab thermometers?

Follow manufacturer guidance and your lab quality plan: calibrate before critical measurements, periodically (commonly annually or semi-annually depending on use), after any drop or damage, and replace batteries or sensors as needed. Keep calibration records and store devices properly.
