Fluorescence dissolved oxygen sensor
Description
The DS380 series of
fluorescent dissolved oxygen sensorsuse a new generation of fluorescence
lifetime technology andhighperformance fluorescent materials. No oxygen
consumption,o flow rate limitation, no electrolyte, no maintenance and
calibration,no interference from hydrogen sulfide, excellent stability.
Built-intemperature sensor, automatic temperature compensation. RS485 output,
can be networked without a controller.
Features
Digital sensor, RS485 output, support
MODBUS
No film, no electrolyte, no interference,
no need for frequent calibration
No oxygen consumption, no flow rate limit
Built-in temperature sensor, automatic
temperature compensation
