DATATRACE (temperature data loggers)

Key functions

Heat-resistance of the body (140 ℃)

The data loggers can measure the atmospheric temperature/pressure/humidity inside equipment and facilities during retort/autoclave , fryer, and dry-heat sterilization.

Compact and light (18 mmφx 20 mm,17 g)

They are easy to attach to equipment and enable precise measurement of the temperature/pressure/humidity.

Cordless type

Micropack’s cordless feature helps prevent accidents, such as disconnection of the sensor from the equipment, even during a mobile process and, consequently, reduces time and manpower requirements.

Users can exchange batteries by themselves

Battery life is approx. 3 months.

A lineup of a wide range of sensors.

A wide range of sensors allows the measurement of different processes and for different uses.

When integrated with heat-resistant containers, the data logger can measure up to 400 ℃.

A wide range of fixtures

The use of fixtures makes it easier to attach the sensor to products and equipment. We can also design and provide new fixtures.

Various types of loggers, such as temperature data loggers, pressure data loggers, and relative humidity data loggers, are available for various uses. Datatrace products have been employed by more than 1,000 companies for the past 20 years, and are the No.1 selling data loggers in Japan.
