LD MULTICHANNEL control instruments are a series of multiple reading
digital systems 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).
- 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)
- mA output (optional).
