Tinytag Talk Thermistor Probe

Small and highly flexible, this probe is ideal for use in confined and hard to reach locations. With a temperature range of -40°C to 125°C, it has the fastest response time of any unit in our range. It is typically used for environmental monitoring and for pipe-work monitoring. Please note: the probe is supplied with the logger, so separate ordering is only required for spare or replacement probes.
