The meter offers strong accuracy supported by automatic calibration checks every 50 power cycles and field calibration for the non-invasive mode, which helps maintain trustworthy results over time.

The large, clear display and enhanced battery life (three times longer than earlier models) ensure it’s easy to use for extended periods without frequent recharging or confusion over readings. Bluetooth connectivity is a modern plus, allowing users to save and download measurements through the Protimeter app with time and date stamps, which is great for keeping detailed records. Customizable options like auto shut-off, backlight, and buzzer improve usability, letting users tailor the device to their workflow.

This dual method is useful for both thorough moisture diagnosis and quick checks. The meter also includes a hygrometry feature to monitor indoor humidity, helping assess ventilation and air quality related to moisture problems. It comes with handy extras such as a heavy-duty moisture probe, calibration check device, and software, all packed in a durable hard case, making it convenient for field use. The display and readout are clear enough for easy interpretation, and calibration options ensure reliable accuracy over time.
