March 2017 – The new and fully contact-free data logger "Patbox" from Witt-Gasetechnik is a highly mobile solution for measuring pressure and temperature rapidly and accurately everywhere in production.

This compact instrument with OLED colour display is really easy to operate: The Patbox does not have to be connected, but instead registers pressure and temperature via integrated sensors.

This allows the setting and monitoring of machines that work with vacuum, for example inert gas packaging. Even the control and setting of pressurized lines is possible using this practical box.

Once initiated via the button or timer, the box registers its measurements at intervals of 100 ms, 1s, 10 s or 1 min. The logging runs until cancelled by pressing a button, or until the memory is full or the battery empty. The internal flash chip records 600,000 entries: at ten measurements per second, extremely precise progress monitoring over up to 16 hours is also possible in addition to purely random sampling.

Only 90x50x20 mm in size, the Patbox communicates pressure and temperature data via the NFC standard. This cordless near field communication based on RFID ensures simpler data transmission – an advantage in comparison to USB as in other systems. The measuring range extends from 1 to 2,000 mbar or -20 to 60 °C. The data can be read via a smartphone or tablet app for Android.

The 550 mAh battery is charged wirelessly on a charging base. According to the manufacturer, 1.5 to 7 days operating time are possible once charged, depending on the measuring interval. The device is also waterproof and dustproof according to IP55.
