Light source Class 1 LED (light emitting diode) with peak wavelength of 610 nm.
Estimated 50,000 hours minimum life; hard water and soft water
indicator.
Detector Silicon photo detector
Optical path length 8.89 mm (0.35 in.)
Time delay One reading above the trip point is necessary to trigger a soft-to-hard
water alarm transition. One reading below the trip point is necessary to
trigger a hard-to-soft water alarm transition.
Trip point 0.3, 1, 2, 5, 10, 20, 50 and 100 mg/L. Refer to Trip point specifications
on page 4.
Reagents Buffer and indicator solution. 500 mL of each reagent every 2 months.
Reagent shelf life 1 year
Power requirements 115/230 VAC, 70 VA, 50/60 Hz, 1.25 A Fuse
Electrical connections Two 3-wire barrier terminal blocks. Wire range: 18–12 AWG
(0.75–1.0 mm

)
Hard water alarm relay SPDT relay, set to on when the hard water indicator is on. The alarm
can be disabled.
Contact rating 5 A resistive at 100–240 VAC
Operating temperature 5 to 40 °C (32 to 104 °F)
Storage temperature -40 to 60 °C (-40 to 140 °F)
Operating humidity Relative humidity: 5–95% at different temperatures, non-condensing
Sampling rate New sample: every 1.9 minutes ±5% at 60 Hz; 2.3 minutes ±5% at
50 Hz
Sample flow rate to sample conditioning 50 to 500 mL/minute flow rate necessary (250 mL/minute
recommended)
Inlet pressure to instrument 1 to 5 psig (0.07 to 0.34 bar), 1.5 psig (0.1 bar) is optimum, > 5 psig
(0.34 bar) can cause sample tubing failure
Inlet pressure to sample conditioning 1.5 psig to 75 psig (0.1 to 5.2 bar)
Inlet fitting At instrument, 6.35 mm (0.25 in.) OD polyethylene tubing with quick-
disconnect fitting
