Lutron YK-2001PHA is a handheld multi-purpose water meter for pH/ORP, conductivity/TDS, salt and dissolved oxygen. It is supplied with the CDPB-03 conductivity/TDS/salt probe; pH, ORP, ATC and oxygen probes are optional. Backlit LCD, data hold, max/min record and RS232/USB output.
The Lutron YK-2001PHA is one handheld meter for multi-purpose water measurement: pH/ORP, conductivity/TDS, dissolved oxygen and salt. It measures pH from 0 to 14.00 pH, ORP within ± 1999 mV, conductivity in four ranges (200 uS / 2 mS / 20 mS / 200 mS), dissolved oxygen from 0 to 20.0 mg/L and salt from 0 to 12 % salt (% weight).
Each quantity is measured with its own separate probe, which makes the meter easy to use in different measurement environments. The Conductivity/TDS/Salt probe CDPB-03 is included; the pH electrode, ORP electrode, ATC temperature probe and dissolved oxygen probe are optional. The dissolved oxygen function uses a polarographic type oxygen probe with a built-in temperature sensor, automatic temperature compensation and adjustable "% SALT" and "Mountain Height" compensation values.
The meter is built around a microcomputer circuit and has an LCD with green backlight, data hold, maximum and minimum recording and an RS232/USB PC computer interface. It is powered by a DC 9V (006 P) battery or a DC 9V adapter.
