Portable multi-purpose meter for pH/ORP, conductivity/TDS, dissolved oxygen and salt in one unit. Supplied with the CDPB-03 conductivity/TDS/salt probe; pH, ORP, dissolved oxygen and ATC probes are optional. Backlit LCD, data hold, max/min record and RS232/USB output.
The Lutron YK-2001PHA is one meter for multi-purpose operation: it measures pH/ORP, conductivity/TDS, dissolved oxygen and salt, each with its own separate probe so the instrument is easy to use in different measurement environments. It covers pH 0 to 14, ORP -1999 to 1999 mV, conductivity in four ranges (200 uS, 2 mS, 20 mS, 200 mS), salt from 0 to 12 % (% weight) and dissolved oxygen from 0 to 20.0 mg/L.
The meter is supplied with the CDPB-03 carbon rod conductivity/TDS/salt probe. The pH electrode (any pH electrode with BNC connector), ORP electrode, polarographic dissolved oxygen probe OXPB-11 and ATC temperature probe TP-07 are optional accessories. pH measurement supports automatic (with the ATC probe) or manual temperature compensation and auto calibration at pH 7, pH 4 and pH 10 or other values; conductivity measurement has automatic temperature compensation with a selectable temperature coefficient.
A microcomputer circuit, an LCD with green backlight, data hold, maximum/minimum recording and an RS232/USB PC interface make it suitable for water conditioning, aquariums, fish hatcheries, beverage and food processing, laboratories, the paper and plating industries, quality control and education.
