BL 983314 is a simple to operate resistivity controller designed for ultra pure water, reverse osmosis, and water conditioning applications. The BL 983314 resistivity controller is also ideal for continuous monitoring of process solutions. Set point and calibration are manually adjusted with a trimmer and the alarm relay allows for simple control.
Readings are automatically temperature compensated, with three different coefficients (β=2.4, 3.5 or 4.5 %/°C). The alarm contact can be used for connection to an alarm, pump, solenoid or dosing system.
The relay contact is open when readings are higher than the set point, while for measurements lower than set point, the relay contact is closed. The Hysteresis is typically 0.20 MW/cm from the set point.
Measurements are displayed on the LCD and the multicolored LED continuously indicates if the controller is in measurement, dosing or alarm mode. Users can choose automatic or manual dosing mode with a switch on the front panel. Manual control is particularly useful during maintenance operations, because it permits operators to enable or disable the dosing relay according to need.
The overtime control system advises users when the relay is active for too long, helping to prevent over-dosage.
Order Information: BL 983314-0 (12 VDC) and BL 983314-1 ( 115/230V) are supplied with mounting brackets, transparent cover and instruction manual.

6,000 + (and growing) factories in our existing network are eager to make it for you.
When it comes to selling in stock products, we are no difference from many other Internet retailers, but we take pride in going extra miles to do something special for you: Have some products custom made for you.
We cannot do everything, but we usually can accommodate a certain changes in product options such as color, size, material, or minor design twist. We primarily work with vendors or factories, not individual artist or craftsman. For custom made products, we usually only cater to bulk size order that meets the minimum quantity requirement of a single factory run. Don't be shy. Ask. What we can accomplish may surprise you!
