Isotech TTI-10 Handheld Thermometer

The Isotech TTI-10 is a high-quality handheld thermometer that combines the accuracy of a laboratory instrument with the flexibility of a portable meter. With two Pt100 inputs, a resolution of up to 0.001 °C and an accuracy of up to 10 mK, the TTI-10 is ideal as a reference thermometer when using Isotech calibrators such as the Isocal-6, Fast-Cal and Dry Block systems. The TTI-10 also comes into its own in industrial and scientific applications where high precision is required.

High accuracy in a compact instrument

Despite its compact size, the TTI-10 delivers performance normally reserved for benchtop models. The thermometer supports a temperature range from -200 °C to +850 °C, with a resolution of 0.001 °C in the most critical range. The instrument accuracy is ±0.012 °C from –80 °C to +200 °C, and ±0.02 °C ±0.0015% of reading up to 660 °C. This performance makes the TTI‑10 particularly suitable as a portable reference for on-site or field calibrations.

Designed for ease of use

The TTI-10 features a clear two-line LCD display that can show one or two channels simultaneously. Operation is simple and intuitive, with clear buttons for functions such as MAX, MIN, HOLD and AVERAGE. The instrument comes with a protective rubber housing that provides extra grip and shock resistance during field work. The high-quality Lemo connectors ensure a reliable and stable connection of Pt100 sensors.

Logging and data processing

The TTI-10 can store up to 4000 measurements and automatically records minimum, maximum and average values. The logging interval is adjustable from 1 second to 30 minutes, making the instrument suitable for both rapid measurements and long-term monitoring. Via the USB interface, the TTI-10 can be connected to Isotech Cal Notepad software for graphing, logging and further analysis.

Smart system calibration

A particularly useful feature is the learning calibration mode. This allows the TTI-10 to be easily calibrated as a system, together with a Pt100 sensor. The user only needs to enter the reference temperature; the instrument automatically calculates the necessary corrections. This makes it possible to perform accurate system calibration without complex calculations or ITS-90 coefficients.

Compatible with Isotech Semi-Standard PRTs

The TTI-10 is designed to work optimally with Isotech’s Semi-Standard Platinum Resistance Thermometers. In combination with these sensors, a total system uncertainty of 20 mK can be achieved.

Isotech offers several recommended probes, including:

> 935-14-112/TTI – fast response, low strain conduction
> 935-14-61/TTI – fast response, robust handle
> 935-14-116/TTI – general use, up to 450 °C
UKAS-certified system calibrations are available for each of these probes.

Robust, lightweight and efficient

Weighing only 300 grams and with a battery life of 20 hours, the TTI-10 is ideal for mobile use. The instrument runs on a standard 9V PP3 battery and can also be powered via USB. The sturdy ABS housing and rubber protective cover make the instrument suitable for intensive daily use. The Isotech TTI-10 offers a unique combination of portability, accuracy and ease of use. With its high resolution, smart calibration functions, logging capabilities and compatibility with high-quality Pt100 probes, the TTI-10 is a reliable and versatile solution for both laboratories and field technicians. The instrument is ideal as a reference thermometer for temperature calibrations and delivers performance normally found only in laboratory equipment.
