testo 905-T1 - Compact Penetration Thermometer
The testo 905-T1 is a compact and highly responsive penetration thermometer designed for accurate temperature measurements in liquids, soft or powdery substances, and air. Equipped with a permanently integrated Type K thermocouple probe, it offers a wide measuring range from -50 to +350 °C, with the capability to measure up to +500 °C for short durations (1 to 2 minutes). Its fast response time ensures quick and reliable readings, making it ideal for professionals requiring precise temperature monitoring in diverse environments.

Your Benefits
- Wide temperature range: Measures from -50 to +350 °C; short-term up to +500 °C.
- Fast response time: t₉₉ = 10 seconds in water for quick readings.
- Integrated Type K probe: Long, pointed thermocouple suitable for various substances.
- Pivoting LCD display: Ensures easy reading from multiple angles.
- Lightweight and portable: Includes attachment clip; weighs only 80 g.
Professional Precision & Speed
The testo 905-T1 penetration thermometer is engineered for professionals who demand precision and speed. Its integrated Type K thermocouple probe is designed with a long, pointed shaft (200 mm), making it perfectly suited for immersion and penetration in laboratory work, chemical processing, pharmaceuticals, and HVAC systems.
User convenience is significantly enhanced by the pivoting LCD display, which allows for clear visibility of readings even when probing at awkward angles. Coupled with a battery life of up to 1000 hours and a durable ABS housing that withstands the rigours of daily use, the CE-certified testo 905-T1 is an essential, reliable tool for daily industrial applications.
Tradie Pro Tip: The pivoting display is an absolute lifesaver when you're taking readings in awkward spots like deep vats or tight HVAC ducts. Just remember, while it can handle high-heat bursts up to +500 °C, keep those extreme temperature readings strictly under two minutes to protect the sensor!
