CTCII™ Conductivity Controller / TDS Chemical Treatment Controller / Cooling Tower Controller

The CTCII is an ideal low cost controller for your chemical treatment needs. The single-input controller provides accurate water measurement with conductivity sensors that have built-in temperature compensation. The alarm and single set-point is easily set with the control knob located on the front of the unit, while the clear screw-down lid prevents accidental changes. Adjustable set-point hysteresis prevents relay chattering and improves control.

Two 110VAC powered outlets allow direct connections to dosing pumps for ease of installation. A 3/4'' NPT(M) conductivity sensor with a 10-ft cord that provides temperature compensation between 32 to 212°F (0 to 100°C) at pressures up to 75 psi @ 140 °F (60°C). Add accessory flow switch and manifold to complete the installation.

Designed Specifically for Chemical Treatment - excellent for Cooling Towers

The unique circuitry of the CTCII™ Chemical Treatment Controller guarantees accurate and reliable measurements. Drift free performance is assured by “field proven” electronics, including automatic DC offset compensation and highly accurate drive voltage.

Since Temperature Compensation is at the “heart” of accurate water measurement, all MyronL CTCII controllers feature a highly refined and precise TC circuit. This feature perfectly matches the water temperature coefficient as it changes. All models corrected to 25°C.

Standard on all models are two heavy-duty 10 amp output relays, operating on increasing readings. Bright red/green LED indicates above or below set point values.

All CTCII models feature a compact IP65/ NEMA 4X water resistant and corrosion proof rated enclosure 4.7 x 6.3 in./120 x 160 mm. They are suitable for bench or surface mounting.

4 MODELS TO CHOOSE FROM*:

• CTCII

• CTCIIT (with Limit Timer)

• CTCIID (with 3-1/2 Digit LCD)

• CTCIITD (with Limit Timer & 3-1/2 Digit LCD)
