At present four types of temperature sensors with a variety of design and operating characteristics can be manufactured by MicroSensor Company.
They are:-

Ge-on-GaAs film resistance thermometers
Several versions of Ge-on-GaAs film resistance thermometers with different operating characteristics have been developed. They are intended for operation in different temperature ranges and identified, and differentiated by the labels TTR-x.
    TTR-D operating range is from 0.03 to 300 K;
    TTR-G and TTR-L operating range is from 0.3 to 400 K;
    TTR-M operating range is from 1.0 to 400 K;
    TTR-2 operating range is from 70 to 450 K;
    TTR-3 operating range is from 200 to 500 K.
Dual element thermometer (DERT)
The DERT has been designed to provide temperature measurements over a wide range, from ultralow to high temperatures, with high sensitivity and resolution over the whole range. This is achieved by using two Ge-on-GaAs film resistor elements combined in a single package which have high sensitivity over complementary ranges within the extended temperature range.

Dual function sensor (DFS)
The DFS has been developed to provide concurrent and coincident measurements of temperature (1.5 K to 400 K and 0.1 K to 400 K) and magnetic fields (up to 30 T). The DFS consists of a Ge-on-GaAs film resistance thermometer and an InSb-on-GaAs film Hall-effect magnetic field sensor combined in a single package. The DFS approach can be applied to the problem in cryogenic thermometry of temperature measurements in high magnetic fields, since, by simultaneous, direct measurements of temperature and local magnetic field, and knowledge of the field sensitivity of the thermometer it is possible to compute a correction for the field effects on the thermometer, and to provide in a compact way both temperature and magnetic field information.

Ge-bulk resistance thermometers
Several versions of Ge-bulk resistance thermometers with different operating characteristics can be produced. They cover the operating temperature range from 0.3 to 300 K.

Si diode temperature sensor for measurements of temperature in the 1.5 K to 450 K range.

The sensors provide:

    wide temperature range for operation (0.03 K to 500 K) 
    monotonic response over a wide temperature range
    small temperature reading errors for operation in magnetic fields
    small size
    extremely fast response to temperature changes
    high radiation tolerance
    high quality and low price

We also develop and produce special-purpose devices such as microcalorimeters and multi-purpose sensors. You can order it.
