T4000 – the professional multifunction measuring device

The T4000 is a modular multifunction measuring device for professional applications in fields such as water damage restoration, building diagnostics, leak detection, and material testing.

As a central measuring unit, the T4000 works with interchangeable sensors and electrodes. Depending on the connected component, it can record material and wood moisture, indoor climate, deep-seated moisture, air flow, or leaks via H₂ tracer gas.

This makes the T4000 an alternative to several specialized individual devices and supports structured measuring processes – from the initial orientation measurement to the documented project completion. Sensors from the T3000 series are compatible with the completely newly developed successor model, the T4000, via an adapter cable. Thanks to full cross-compatibility, both T3000 sensors can be used on the T4000 and new T4000 sensors on the T3000.

The T4000 is designed for daily use under demanding conditions. The shock-resistant housing with non-slip rubber coating reliably protects the electronics. The scratch-resistant Panda Glass 7H display is shatterproof and designed for the mechanical stresses of construction site use.

The LP12 Quick-Connect system allows for easy operation even when wearing gloves. Sensors can be changed in seconds without the need for tools. The base unit remains the same; only the sensor technology is adapted to the respective measurement application.

Result: A measuring device for professional continuous use that works and measures reliably even under high stress.

Depending on the connected sensor or the electrodes used, the T4000 supports various measuring principles:

Capacitive sensors allow for non-destructive surface analysis of building materials. High-quality resistance electrodes enable quantitative measurements in wood and building materials. In doing so, the T4000 takes into account over 200 stored wood species, including temperature compensation. Climate sensors record temperature, humidity, dew point, absolute humidity, and specific humidity. A heated sensor element reduces measurement drifts in high humidity or due to deposits. Optionally, special sensors enable H₂ tracer gas detection for leak location.

All these types of measurement require the appropriate sensor or electrodes – the measuring device forms the common basis. This results in reliable measurement results that make causes visible and enable well-founded decisions.

Measured values are stored in the device or archived on microSD. The internal memory, in combination with an exchangeable microSD card, allows for extensive measurement series as well as continuous long-term recordings even over years. Via Bluetooth, they can be transferred to the MultiMeasure Mobile app, where measurement series are visualized, projects are organized, and reports are created.

The expandable memory allows for long-term recordings over months or years – for example, to monitor drying processes or indoor climate developments.

Firmware updates are carried out over-the-air or via microSD. New functions can be installed directly on the device without having to send it in.

A wide range of compatible SDI sensors is available for the T4000, including climate sensors (e.g., TS220SDI, TS240SDI), capacitive material moisture sensors (TS670SDI), and sensors for H₂ tracer gas for leak detection. The sensors are automatically recognized and allow for the targeted expansion of the measuring system depending on the application, from building diagnostics and climate assessment to water damage analysis.

For resistance measurements, the system supports various electrode families, including round, flat, ram, and hand electrodes, as well as insulated versions for measurements in multi-layer components. The range is complemented by special electrodes for wood, screed, and insulation materials. This allows the T4000 to be precisely adapted to different materials and measurement situations.

The accessory portfolio includes adapter cables for integrating existing T3000 sensor technology (e.g., TC35), connection cables, replacement and special tips, a test block for accuracy checks, and additional system accessories for maintenance and expansion. This allows existing sensor technology to continue to be used, measurement accuracy to be regularly checked, and the system to be expanded as needed – an important foundation for long-term professional use.
