Industrial Conductivity Meter Converter 'WDM-135A/WDM-136A'
Easy to operate 2-electrode type! An industrial conductivity (electrical conductivity) meter converter that allows you to change the measurement range to 10 different settings for each cell constant.
The WDM-135A model (2-wire type) / WDM-136A model (4-wire type) is a compact and robust aluminum-cased, easy-to-operate 2-electrode field-installed conductivity (electrical conductivity) meter converter (transmitter). It supports a wide measurement range from ultra-pure water (0–0.2 μS/cm) to industrial wastewater (0–20 mS/cm) and a wide temperature compensation range from -5 to 120°C. There are 2-wire (DC 24V power supply) and 4-wire (AC-free power supply) options, with a transmission output of DC 4–20 mA. 【Features】 ■ Wide measurement range ■ Adjustable measurement range ■ Temperature measurement display ■ Self-diagnosis ■ Automatic return to measurement mode *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Other Features】 ■ The measurement range can be changed to 10 types for each cell constant. ■ Displays the temperature of the sample water (-5 to 120℃). ■ Measurement values can be adjusted to known electrical conductivity values (adjustment range: measurement value ±10%). ■ Equipped with a burnout function that alerts to abnormalities by driving the transmission output to the upper or lower limit when there is a failure in the measurement system, such as abnormal temperature compensation resistance or memory element failure. ■ Automatically returns to measurement mode after 2 hours in maintenance mode. *For more details, please refer to the PDF document or feel free to contact us.
