Greisinger GTF 401 Sonda de inmersión Pt1000, -50 a +400°C, jack 3,5 mm 100670

Measuring temperature in liquids, air, or gases with a standard multimeter can be inaccurate and slow. The Greisinger GTF 401 immersion probe solves this by providing a fast, precise Pt1000 sensor in a robust stainless steel tube, designed for direct connection to compatible Greisinger thermometers.

Who is it for

Laboratory technicians, HVAC engineers, and industrial maintenance staff who need reliable temperature readings in fluids or gases and already use Greisinger handheld instruments with a 3.5 mm jack input.

Main features

• Pt1000 sensor element (DIN EN 60751, Class B) for high accuracy and stability.
• Wide measurement range: -50 to +400 °C at the probe tip, -50 to +250 °C at the handle and cable.
• Fast response: approximately 5 seconds (t90) in water.
• Durable stainless steel probe tube, 3 mm diameter, 100 mm length, with IP65 protection on probe and handle.
• 1 m PVC cable with 3.5 mm stereo jack plug for direct connection to Greisinger GTH 1150, GMH 3xxx, and GMH 5xxx series.

Tips

For best accuracy, immerse the probe tip at least 50 mm into the medium and allow a few seconds for thermal equilibrium. Avoid bending the cable sharply near the handle to prolong its life.
