Sonda a immersione testo 0628 7503 sensore di temperatura -30 a 90 °C, modello 0628 7503 di testo

The testo immersion probe 0628 7503 is a temperature sensor designed for direct immersion measurements in liquids and semi-solid media over a range of -30 to 90 °C. Intended for use with compatible testo instruments, the probe provides rapid, reliable temperature readings for process control, HVAC verification, laboratory testing and food safety checks. The probe's construction supports routine monitoring where an immersion sensor is required and where accurate temperature feedback is needed to maintain product quality or system performance.

Advantages

The immersion probe offers a compact design suitable for insertion into fluids and pastes, delivering consistent measurement across its specified temperature range. Its construction minimizes response time and supports stable readings in continuous or intermittent measurement tasks. The probe is compatible with testo devices that accept this probe type, enabling straightforward integration into existing test routines. Materials and design focus on practical handling and reliable operation in environments such as process lines, HVAC systems, laboratories and food production facilities.

Suitable for

• Temperature checks in liquids (water, oils, process fluids)
• Measurements in semi-solid samples and viscous media
• Routine process control and HVAC system verification
• Laboratory testing where direct immersion is required
• Food industry temperature monitoring during production and quality control

Key specifications

• Measurement range: -30 to 90 °C
• Sensor type: immersion temperature probe for direct insertion
• Compatibility: fits testo instruments accepting this probe model
• Intended media: liquids and semi-solid substances
• Typical application areas: process control, HVAC, laboratory and food industry

How to use

Connect the immersion probe to a compatible testo instrument according to the instrument's input requirements. Insert the probe tip directly into the liquid or semi-solid sample to the recommended immersion depth for accurate measurement; ensure the sensor element is fully immersed and avoid contacting container walls or bottom if this may affect readings. Allow the reading to stabilise before recording values. After use, follow the manufacturer's guidance for cleaning and storage appropriate to the sampled media.

Recommendations

For reliable results, choose an appropriate immersion depth that covers the sensor element, avoid mechanical stress on the probe shaft, and clean the probe after contact with food or corrosive media. Verify compatibility with the testo instrument before use and consult the instrument manual for calibration and connection details.
