The testo 905-T1 penetration thermometer has a large measuring range from -50 to +350 °C and can even measure up to +500 °C for a short time (1 to 2 minutes). Its permanently integrated type K thermocouple probe makes this possible. In addition, the penetration thermometer is characterised by its short response time. The thermocouple probe reacts very quickly, particularly in water (or other liquids). The penetration thermometer is therefore ideally suited for measurements in fluid substances in laboratory, chemical and pharmaceutical areas. However, as well as immersion/penetration of the long, pointed probe shaft in liquids and soft or powdery substances being possible, you can also insert it in ventilation ducts to measure the temperature there. The penetration thermometer is also a winner when it comes to accuracy, because it achieves a higher level than typical comparable models.
