Product Detail

Manual

Brief Introduction

This instrument can measure temperature, optical dissolved oxygen, fiber optic turbidity, four-electrode conductivity, pH, salinity, etc. The BQ401 multi-parameter handheld probe can support up to 4 types of probe measurements. When connected to the instrument, these data can be automatically identified. This meter is equipped with a backlight display and operation keyboard. It has comprehensive functions and simple operation. The interface is simple. It can also realize measurement data storage, sensor calibration and other functions at the same time, and it can export USB data to achieve more high-end functions. The pursuit of high cost performance is our consistent pursuit.

Features
