Product name	Compact City Water Analyzer
Model	: MWB4-72
Objects measured	: Three basic items (turbidity, color, and
	residual chlorine), electric conductivity,
	pH, temperature, and pressure
Measurement	: Ability to switch between two ranges for
range switching	both turbidity and color measurements.
Display	: Color LCD touch panel
Temperature	: 0 to 40°C for residual chlorine, EC, and
compensation range	pH
Response time	: 90% response within three minutes
Operating power	: 100 to 240V AC ±10%, 50/60Hz
Power consumption	: Approx. 40/55VA (100/240V AC), max.
	of approx. 83/108 VA (100/240V AC)
Transmission	: DC 4 to 20 mA, isolated
output	( Negative (-) side is common.)
Load resistance	: 600Ω or less
Contact switching	: Alarm 1; General alarms (measured value
output signals	High-High/Low-Low limit alarm, light source
	error, residual chlorine motor error, sensor
	error, and start-up mode error)
	Alarm 2; General alarms (concentration
	upper/lower limit alarm, water temperature
	compensation error, and auto calibration error)
	Maintenance; When in ST-BY mode
	Event; During auto cleaning, during auto
	calibration, and during problem diagnosis
	(Contact capacity for all of the above; 24
	VDC 0.2A resistance load))
	Power cut off; The contact is closed when
	a power failure occurs.
	(Contact capacity; 30 VDC 0.2A
	resistance load))
Contact switching	: Cleaning command; When the closed
input signals	contact receives, cell window cleaning
	starts (turbidity / color).Start cell window
	cleaning (turbidity / color)
	Calibration request; When the closed
	contact receives, automatic zero
	calibration starts (turbidity / color / residual
	/ residual chlorine).Start automatic zero
	calibration (turbidity / color / residual chlorine)
	(Resistance load; 200Ωor less, Pulse
	duration: 500mS or greater)
Communication	: RS232C interface or RS485 interface
system	(isolated)
	Communication speed; 9600 BPS
	Synchronous system; Start-stop
	synchronization
	Control system; Half-duplex
	communication system
	One line for communication (dedicated
	cable or connector), one line for
	maintenance (D-SUB connector)
Save functionality	: Data such as measurements can be
	transferred to a memory card.(Compact
	Flash,CF) They can also be processed by
	a computer.
	One minute measurement values can be
	stored in 3-month intervals, and one hour
	values can be stored in 1-year intervals.
Sample water	: No suspension or stagnation.
conditions	Quality; Ensures that the water quality
	(excluding the items below) satisfies the water
	quality standards set by the Water Law or falls
	within the measurement range of this unit.
	Temperature; 0 to 40°C (no freezing)
	Pressure; 0.05 to 0.75MPa
	pH; 5.5 to 8.6 pH (maximum fluctuations; 1pH)
	EC; 8 mS/m (80µS/cm) or greater
	Flow rate; 50 to 100 mL/min
Sample	: 5m3/month or less (9m3/month, including
consumption	a by-pass flow of 100 mL/min)

Automatic calibration	: Zero calibration for turbidity, color, and
	residual chlorine. The internal timer and
	an external contact signal are used to
	start calibration.

	calibration; Calibration time approx. 13
	min. + 9 min. (fixed)
Automatic cleaning	: The internal timer and an external contact
	signal are used to start backwashing (by
	draining the water) to clean the cell
	window for turbidity and color measurements.
	Cleaning cycle setting: 10, 15, 20, 30, or
	60 min.
