Additional Details

The ZS-ABB is a portable industrial temperature and humidity data reader designed for field inspections, sensor configuration, equipment testing, and multipoint temperature monitoring.

Featuring an upgraded 3.2-inch color display and enhanced driver software, the device provides a convenient way to inspect and configure digital temperature monitoring systems without requiring a permanently installed computer or monitoring station.

The handheld reader supports both two-wire and three-wire sensor configurations, with compatibility across a range of digital temperature and humidity sensor chips. It can monitor up to 200 measurement points per channel and supports extension cable lengths of up to 700 meters when used with compatible sensors.

Built-in sensor identification tools allow users to modify cable numbers and individual sensor level identifiers directly from the device. These functions simplify sensor commissioning, system configuration, and troubleshooting during installation or maintenance.

The ZS-ABB also includes onboard storage for up to 32 measurement records, allowing users to review historical temperature readings and compare measurements taken at different times.

For installations involving long cable runs or unstable sensor communication, a dedicated long-distance measurement mode prioritizes reading stability over measurement speed.

Its rechargeable cold-resistant battery, USB Type-C charging interface, and portable design make the ZS-ABB suitable for industrial facilities, coal storage systems, water tanks, geothermal monitoring installations, ground-freezing shafts, and other distributed temperature monitoring applications.
