AT42 Portable Single-Channel Temp

AT42 Portable Single-Channel TempThe AT42 TEMP is an easy-to-use, portable, single-channel temperature training instrument. Its BUILT-IN MICROPROCESSOR collects and analyzes session data, and presents temperature information in ways that are easier than ever to understand.

AT42 TEMP Features

  • Calculation and display of summary statistics (session mean, max., min., and SD).
  • Temperature display in F or C.
  • Temperature feedback resolution of 0.1 or 0.01 (user selectable).


All AT42 TEMP features are AT YOUR FINGERTIPS. A press of the desired button will change control settings, record or display session data, or select a feedback option.

Exclusive TPI

The AT42 TEMP is the only portable temperature feedback instrument with time period integration (TPI). The TPI feature allows a selectable rate of temperature feedback to the patient. It can provide the absolute temperature in real-time -- or the mean temperature every 1.0, 2.0, 4.0, 10.0 or 60.0 seconds.

TPI values, along with the session mean from the AT42 TEMP's Statistics feature, can be used to DEMONSTRATE IMPROVEMENT both within each session and from session to session.

AT42 with accessories and carrying caseSuperior Feedback

Audio: The AT42 TEMP's audio synthesizer, creates new opportunities for "user-oriented" audio feedback. It provides conventional audio feedback as well as new types of feedback which distinctly indicate the RATE AND DIRECTION of temperature change. Audio feedback selections include:

1. Melodic piano tone,
2. Percussive piano tone
3. Ten tone, and
4. Bi-tone.

Visual: The AT42 TEMP features two visual feedback selections:

1. an LED numerical display that reads out absolute temperature in F or C, and
2. a 10-segment LED lightbar.

Simply Better

The AT42 TEMP is the intelligent choice in temperature biofeedback. It combines USEFUL FEATURES, unavailable on any other instrument, with an affordable price.


The AT42 TEMP is designed to meet/exceed the electrical and safety standards specified by UL 2601, IEC 601 and CSA 871. The default parameters are bolded.
