Description
TPN 390 / EB 334-N surface probe is a dedicated temperature sensor for surface contact measurements across the extended range of -50 °C to +800 °C. This temperature probe serves as an accessory for climate measuring instruments, enabling accurate surface temperature determination in laboratory, process and industrial environments. Supplied as a single piece, it offers a compact form factor suited to routine thermal monitoring tasks. The TPN 390 / EB 334-N model from manufacturer Ebro - a Xylem brand integrates readily into existing climate instrumentation setups where surface rather than immersion or air sensing is required. With a net weight of 0,125 kg and gross weight of 0,15 kg, the probe remains lightweight yet practical for frequent handling. It supports precise data collection on equipment surfaces, materials and process components across a broad thermal window. Ideal for professional climate-control workflows and quality-assurance checks, the sensor helps maintain measurement consistency without unnecessary complexity. Its specialised design addresses applications that demand reliable high-temperature surface readings in demanding laboratory and technical settings.

Questions about TPN 390 / EB 334-N, Surface probe up to +800°C
What is this article?
TPN 390 / EB 334-N, Surface probe up to +800°C is the article on this page. Luminix Health distributes Ebro - a Xylem brand for laboratory use. It sits in Temperature probes & sensors, inside Temperature measurement, in Lab instruments.
A temperature probe is the sensor, Pt100, thermocouple or thermistor, that a meter or a logger reads. The probe, not the display, is what is calibrated. The sheath material and the response time matter in a liquid versus a block.
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.
