Testo 905-T1 - Penetration Thermometer

Testo 905-T1 Overview

The Testo 905-T1 is a compact penetration thermometer with a permanently integrated Type K thermocouple probe, covering a large -50 to +350 °C measuring range. Its fast response time makes it especially effective in liquids and semi-solid media, and the swivelling display can be turned to the best reading angle. Small enough to keep in a pocket, it is an everyday tool for laboratory, chemical, pharmaceutical and industrial temperature checks.

Who the Testo 905-T1 is for

The Testo 905-T1 is for lab, chemical and pharmaceutical technicians, process and maintenance staff, and anyone who needs a quick reading inside a liquid, a paste or a duct without a separate probe and cable. Its fixed Type K probe reaches temperatures that many pocket thermometers cannot, and testo says it is especially accurate in the upper part of its range.

From the testo 905 data sheet (0981 9284):

• Accuracy ±1 °C from -50 to +99.9 °C and ±1% of reading above that, referenced to +25 °C
• 0.1 °C resolution on a one-line LCD that swivels for easier reading, with auto-off
• 3 × AAA cells give about 1000 hours of use
• Instrument operating range 0 to +40 °C; storage -20 to +70 °C
• 80 g, and supplied with an attachment clip

See all thermometers or the Testo brand page. For surfaces such as pipes and plates choose the Testo 905-T2; for interchangeable Type K probes the Testo 925; and for food checks the Testo 106. All figures are in the official testo 905 data sheetPDF.

Testo 905-T1 FAQ

Short answers about the Testo 905-T1:

• Can the Testo 905-T1 measure above 350 °C? Yes, for a short time. testo allows readings up to +500 °C for 1 to 2 minutes.
• How fast does the Testo 905-T1 respond? About 10 seconds to t99 in water.
• How deep can the Testo 905-T1 probe be immersed? testo’s instruction manual allows a maximum of 180 mm of the 200 mm probe shaft, and warns that media hotter than 350 °C can damage the housing.
• Can the probe be replaced with a different one? No. The Type K probe is fixed to the instrument; for plug-in probes use a Testo 925.
• What is the difference between the 905-T1 and the 905-T2? The 905-T1 has a pointed probe for immersion and penetration; the 905-T2 has a sprung cross-band head for surfaces and reaches t99 in about 5 s.
