Description
Temperature sensor TFK 325 is an NTC temperature probe rated at 30 kiloohms and fitted with a banana plug connection of 2 × 4 mm for use with compatible portable pH measuring systems. Intended for WTW pH meters, the sensor supports temperature acquisition alongside pH determination in laboratory and field measuring workflows where reliable thermal input is required by the instrument. The compact single-piece unit weighs 0,050 kg, making it convenient for portable meter kits, bench setups, and routine calibration or measurement sequences. Connection via dual 4 mm banana plugs allows straightforward attachment to matching meter inputs without additional adapters when the instrument interface is designed for this format. From manufacturer WTW, the TFK 325 belongs to the measuring-instrument range focused on pH value determination and portable pH meters. Laboratories use such NTC sensors to provide the temperature data needed for accurate pH evaluation and temperature-compensated readings. The clear specification—NTC 30 kiloohms with 2 × 4 mm banana plugs—helps ensure correct pairing with designated WTW pH meter models. Supplied as 1 pc, it is suited to replacement, spare-sensor stocking, or initial equipment of portable pH measuring stations in research, quality control, and teaching laboratories.
This article is part of Temperature probes & sensors, in Temperature measurement.

Questions about Temperature sensor TFK 325, NTC 30 kiloohms, banana plug 2 x 4 mm, 1 unit(s)
What is this article?
Temperature sensor TFK 325, NTC 30 kiloohms, banana plug 2 x 4 mm, 1 unit(s) is the article on this page. Luminix Health distributes WTW 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.
