The waterproof 4.7 kΩ NTC thermistor probe is used in experiments to study how the resistance of a negative temperature coefficient semiconducting thermistor depends on temperature. The probe is immersed in a water bath and the current passing through it is measured for known voltage.
Probe: B57891-M472-K
Resistance at 25°C: 4.7 kΩ (±10%)
Coefficient B25/100: 3980 K (±3%)
Maximum temperature: 120°C
Maximum power: 0.2 W
Maximum voltage: 30 V DC
Measurement category: CAT I
Connectors: 4 mm safety plugs
Total length: approx. 0.75 m
Weight: approx. 40 g
