Witt Patbox mobile pressure and temperature data logger

The Patbox from Witt-Gasetechnik is a contact-free mobile data logger for measuring pressure and temperature rapidly everywhere in production.

The compact instrument with OLED colour display is easy to operate. It does not have to be connected, instead registering pressure and temperature via integrated sensors using NFC communication.

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

Only 90 x 50 x 20 mm in size, the product 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 2000 mbar or -20°C 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 seven days operating time are possible once charged, depending on the measuring interval. The device is also waterproof and dustproof according to IP55.
