FAQs

Q1: Which smartphones are compatible with the Bluetooth function?

A: The UT383BT connects via Bluetooth (version 4.0 or higher) using the custom UNI-T “iENV” mobile app. It is fully compatible with Apple devices running iOS 8.4 or higher, and Android devices running version 4.3 or higher.

Q2: What is the maximum illuminance this meter can measure?

A: This digital photometer features a wide measurement range up to 199,900 Lux (approximately 18,500 Fc). If the environmental illumination exceeds this maximum limit, the LCD screen will automatically display “OL” to indicate an overload.

Q3: Can I switch the measurement units between Lux and Foot-candles (Fc)?

A: Yes, absolutely. The device features a dedicated “LUX/FC” button on the front panel. You can easily toggle between Lux (the standard international metric unit) and Foot-candles (widely used in the US) depending on your specific project requirements.

Q4: Will the lux meter store data if I am not connected to the smartphone app?

A: The device itself features a “Data Hold” function and tracks MAX/MIN values directly on its LCD screen for quick field readings. However, to record, store, and export continuous real-time data logs, you must keep the device connected to the iENV app via Bluetooth.

Q5: Is this light meter suitable for measuring LED grow lights for indoor plants?

A: Yes, it is highly recommended for indoor agriculture. You can use this photometer to accurately map the light intensity under your LED grow lights, ensuring your indoor plants are receiving the optimal luminosity for healthy photosynthesis and growth.
