OWON Technology B41T 3-in-1 measurement tool

SKU CH-AEAX-HZ5V4 MPN B41T

A 3-in-1 digital multimeter, data logger and thermometer with Bluetooth multi-device app support and voice safety alerts

  • 3-in-1 multimeter, data logger and thermometer
  • Bluetooth app connects multiple devices for remote monitoring
  • Voice safety warnings alert you during measurements
  • Trend charts analyse changing readings over time
  • Smart voice reading speaks measured values aloud

3-in-1 data logger multimeter thermometer

The OWON B41T combines a digital multimeter, a data logger and a temperature meter in one handheld device. It measures DC voltage up to 1000 V and AC voltage up to 750 V with stated accuracies of ±(0.1 %+10 dig) and ±(1.0 %+25 dig) respectively. Bluetooth connectivity lets multiple units stream readings to a mobile app for remote monitoring.

Voice warnings and trend charts simplify setup

Pairing with the app is straightforward and enables smart voice-reading of live values. Voice warnings sound when measured signals exceed safe limits, reducing the chance of accidental overload. The special chart mode plots change trends on screen so you can spot drift without exporting logs. No driver installation is required on the phone.

Verify your test leads and temperature probe

The meter ships with standard probes for voltage, current and resistance ranges listed in the specifications. Temperature measurement covers -50 °C to 400 °C using a K-type thermocouple, so confirm you have a compatible probe for the expected range. The 21 999-count display and 40 Hz to 10 kHz frequency response suit general electrical and HVAC troubleshooting.

Questions about this item

How can I confirm the B41T is measuring DC voltage correctly after setup?

Apply a known DC voltage source and verify the reading falls within the stated accuracy of ±(0.05%+10 digits) for the 220 mV range or ±(0.1%+10 digits) for the 1000 V range.

What accessories are included with the B41T and what must I buy separately for temperature measurement?

The unit includes the multimeter and Bluetooth data-logging function; a K-type thermocouple probe is required separately to use the -50 °C to 400 °C temperature feature.

Which measurement range should I select on the B41T to resolve a 0.01 µA DC current change?

Choose the 220 µA DC current range, which provides 0.01 µA resolution with ±(0.5%+10 digits) accuracy for fine low-current work.
