Questions about Two-channel data logger testo 184 H1, -20 to +70 °C, 0-100 % RH, 1 unit(s)
What is this article?
Two-channel data logger testo 184 H1, -20 to +70 °C, 0-100 % RH, 1 unit(s) is the article on this page. Luminix Health distributes Testo for laboratory use. It sits in Data loggers, inside Temperature measurement, in Lab instruments.
A data logger stores a temperature, a humidity or another signal over time, so a shipment or a room has a record rather than a spot reading. The interval, the memory and the sensor range are the specification. A logger that is full has stopped being a record.
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.
Which category should I open next?
The category is Temperature measurement. The sub-category is Data loggers. The catalogue is Lab instruments.
