DDG-99B Conductivity Transmitter丨Intelligent Online丨Boiler water surface water

Product Feature

16-bit high-precision A/D and high-performance microprocessor technology, capable of conducting conductivity and temperature test, temperature compensation, instrument self-checking and other functions
Graphic dot matrix liquid crystal, with LED backlighting, with a protective case that can operate under direct sunlight exposure.
The range can be automatically switched, and the range of the output signal can be set arbitrarily within the full range.
Automatic temperature compensation. Select the measured water quality according to different working conditions. Store multiple compensation curves in memory. Press the buttons to correct the temperature compensation coefficient and click the constant.
Automatically adjust the measurement frequency to avoid electrode polarization and improve measurement accuracy

The DDG-99B series conductivity transmitter is a four-wire, single-channel transmitter independently developed by Dongrun Instruments. The transmitter offers more signal output and control functions, making operation more convenient. It is compatible with Dongrun as well as commonly used contact-type two-electrode conductivity sensors in the market.
