Digital thermometers

Choose by what you measure. A penetration probe goes into liquids and semi-solids, such as media, gels or food samples, like the digital thermometer with stainless steel piercing probe. A surface probe has a flat tip for hot plates, heating blocks and other surfaces. A wireless sensor sits in a fridge, freezer or incubator and sends readings without opening the door, such as the wireless temperature gauge. For continuous records, see data loggers. Separate probes are in temperature probes and sensors. Questions? Ask sales@luminixhealth.com.

Resolution is the smallest step the display shows, such as 0.1 or 0.01 °C; it is not the same as accuracy, which tells you how close the reading is to the true temperature. A display with 0.01 °C can still be less accurate than one with 0.1 °C, so read the accuracy on the product page. Then check that the measuring range covers your coldest and warmest application with some margin, as with the multi-channel thermometer with 0.1 °C resolution.

You need one when your quality system, an audit or a customer asks for traceable temperature measurements, for example for fridges, incubators or stability storage. A calibration certificate documents the deviation of the thermometer at defined points. Some thermometers are sold with a certificate, which the product page states; for others, you can order calibration separately in calibration service and certificates. Plan recalibration at the interval your quality system sets. For routine checks without audit requirements, a thermometer without certificate is usually enough. Not sure what your audit requires?

A digital thermometer reads quickly and clearly, and many models store minimum and maximum values or measure several channels at once, such as the electronic max/min thermometer with bar chart. Probes can be replaced and readings logged. A glass thermometer needs no battery, has no electronics to fail and is simple to check against a reference, which is why many labs keep one for baths and ovens; see laboratory glass thermometers. Choose glass for simple fixed points and digital for logging, alarms or several points. Questions? Ask sales@luminixhealth.com.

A digital thermometer is a display plus a sensor. The resolution on the screen can be finer than the accuracy. The stated accuracy and the calibration point are what the number is worth. The probe type has to be the one the meter expects.

A thermometer reports a temperature. A liquid-in-glass thermometer is a calibrated column. A digital thermometer is a sensor and a display, and the sensor, not the display, is what is calibrated. An infrared thermometer reads a surface and depends on emissivity. A data logger stores the reading over time. Without a stated uncertainty and a calibration point, the number is only an indication. The scale is maintained by the BIPM and compared by EURAMET. Accreditation is BELAC.
