Series 50 Multi-parameter Controller
One Controller, One Family of Sensors
Simple, Powerful, Affordable
The Chemitec Series 50 controller combines Plug & Play ease of use with support for multiple parameters. The controller simultaneously supports two separate sensors for two separate measurement parameters, selectable from pH/ORP, turbidity, suspended solids and optical dissolved oxygen. Each parameter is supportable alone or in combination.
▲ Eliminates the need for multiple dedicated controllers
▲ Supports 1 or 2 sensors, reducing equipment costs
▲ Supports addition of a second sensor at a later time
▲ Plug & Play operation with all Chemitec digital sensors
Series 50 Multi-parameter Controller for pH, Dissolved Oxygen, suspended solids, turbidity, Nitrate, Ammonia, Conductivity and Chlorine.
Plug & Play with automatic sensor recognition, 144x144 wall mount, supports up to 2 sensors with RS 485 digital output
Measuring range determined by sensor
Automatic or manual Temperature Compensation
Graphic display for simultaneous display of: size, temp., analog and digital output
(set point), alarms. Keyboard programming (5 digits).
Function keys for calibration and graphic display of measurement data.
Internal data logger (4 Mbit flash) with ability to display graphical and tabular trends of measures with an indication of the minimum, maximum and average of the period. Four programmable set points (2 for each measure) for range and activation time.
Output for alarm: min/max delay set point, residence time, failure.
Output for programming automatic electrode cleaning interval and duration.
Digital input for activation and inhibition assays washing remotely. Three programmable analog outputs 0/4 to 20mA. Programmable limits within the measurement range of the sensor (ability to combine 2 equivalent measurements to generate third output averaging the two measurements).
PID control function can be activated on analog or digital (frequency or pulse).
Serial port RS485 with MODBUS RTU protocol.
USB master module to download data on USB Flash Drive 2.0
