WiFi Temperature Data Logger, Model TD2TC for Interchangeable Thermocouple Probes Type K

The TD2TC is a WiFi temperature data logger with two inputs for interchangeable type K or type T thermocouple probes. It records temperatures at freely configurable intervals and transfers the measurements via WiFi to the ThermaData software. This makes it a flexible alternative to traditional LAN thermometers and wired temperature recorders.

The usable temperature range depends on the connected thermocouple probes. The logger supports:

• type K thermocouples typically from around –100 to +1372 °C, and

• type T thermocouples from approx. –100 to +400 °C.

This means the WiFi temperature data logger can cover deep-freeze, refrigeration, ambient and high-temperature / oven applications.

The TD2TC features two external thermocouple sockets. You can connect:

• type K probes (e.g. for high temperatures, ovens, process monitoring)

• type T probes (e.g. for lower temperatures, refrigeration and freezers)

This turns the ThermaData WiFi TD2TC into a very versatile thermocouple data logger for many different applications.

A LAN thermometer is usually integrated directly into the network via Ethernet cable. The TD2TC operates via WiFi:

• no fixed network cabling required

• flexible placement of the data logger

• access to temperature data over the local network or the internet

• ideal wherever an existing WiFi infrastructure is available

So the TD2TC is a modern WLAN / WiFi temperature data logger, suitable for many locations where there is no LAN socket.

No. The ThermaData Studio software can be downloaded and used free of charge; there are no licence or subscription fees.
The software is used to configure the logger and to visualise, analyse and export the temperature data.

The ThermaData WiFi TD2TC connects to your WiFi router. At the configured logging interval, the logger:

1. stores the readings in its internal memory

2. synchronises the data via WiFi with the ThermaData software or server

In this way, you can set up a complete wireless temperature monitoring system with multiple WiFi data loggers.

If the WiFi or connection to the router is temporarily interrupted, the WiFi temperature data logger continues to record. The TD2TC provides internal memory for up to 18,000 readings (2 × 9,000 per channel).
As soon as the connection is restored, the stored data is synchronised automatically – so no readings are lost.

You can define high and low alarm limits for each channel. If these limits are exceeded or undershot:

• a red LED on the device indicates the alarm status

• depending on the ThermaData solution used, the software can be configured to trigger notifications (e.g. pop-ups or emails)

This makes the logger suitable for HACCP-compliant temperature monitoring in many applications.

Typical applications include:

• monitoring of refrigerators and freezers

• temperature control in ovens, heating cabinets, autoclaves

• laboratories, pharmaceutical and medical environments

• food production, catering, gastronomy

• process and quality control in industry and research

In most cases, wherever you would use a classic LAN thermometer, you can also use this WiFi temperature data logger – with greater flexibility regarding installation and placement.

The TD2TC is typically powered by 2 × AA batteries. Depending on the logging interval and WiFi signal quality, the practical battery life is around up to 12 months.
For critical applications, it is advisable to monitor the battery status in the software and plan regular replacement intervals.

Many versions of the ETI ThermaData WiFi TD2TC are supplied with a traceable calibration certificate or can be ordered with one as an option.
This allows the temperature data logger to be integrated easily into quality-critical processes (e.g. pharma, food, ISO/HACCP).

As long as your existing probes:

• are type K or type T, and

• match the plug/connector type used by the TD2TC,

they can usually be reused. However, for optimum accuracy, it is recommended to calibrate the logger and probes together.

Yes. The ThermaData Studio software can manage multiple ThermaData WiFi loggers (e.g. TD, TD1F, TD2F, HTD, etc.) at the same time.
This allows you to build mixed systems with WiFi temperature data loggers for different locations and accuracy requirements.

Yes, the TD2TC can also be used temporarily as a mobile WiFi thermometer – for example for short-term measurement campaigns or validation tasks. The display shows current temperature, min/max values, WiFi status and battery level on site, while the data is recorded and stored in your system in parallel.
