Control instruments LD MULTICHANNEL PLUS

MULTIPLE READING DIGITAL SYSTEMS WITH PID REGULATION

They are multiple digital measuring systems for complete control of water treatment and chemicals dosage, ensuring, depending on model, the control on acid (pH) and on a second parameter (by customer request different parameters combination can be set).

LD MULTICHANNEL PLUS

CONTROL INSTRUMENT

LD MULTICHANNEL control instruments are a series of multiple reading digital systems with PID regulation that meet a wide range of applications.
They are multiple digital measuring systems for complete control of water treatment and chemicals dosage, ensuring, depending on model, the control on acid (pH) and on a second parameter (by customer request different parameters combination can be set).

LD MULTICHANNEL instruments have: easy control by encoder wheel, flow control, local & remote control, ERMES web communication, permanent data storage with system log, PT100 temperature probe, stand-by input, alarms, programmable delay at dosing start-up (up to 60 minutes), priority dosage, probe readout menu and check-up, multiple probe readings can be viewed, working modes (on/off, impulsive proportional, proportional PWM and fixed PWM), automatic or manual dosing activity, chlorine/bromine selection with ECL6 (LDPHCL), flocculant output 230 VAC (LDPHCL and LDPHRH) and mA output (optional).
