MODEL 399VP pH/ORP SENSOR	SECTION 1.0
	DESCRIPTION AND SPECIFICATIONS

1.3 ORDERING INFORMATION

The Model 399VP pH/ORP Sensor is available with custom glass electrodes housed in a molded Tefzel body with 1 in. MNPT threads suitable for insertion, submersion or flow through installation. The sensor includes a general purpose hemi bulb pH electrode (flat bulb optional) or a platinum ORP electrode and a double or triple junction gel filled reference electrode. Automatic temperature compensation is standard with the Model 399VP pH, but is not required on the Model 399VP ORP (except when used with the Model 1054A ORP Microprocessor Analyzer). The 399VP is offered with the Variopol (VP) connector and uses a mating VP cable (purchased separately). A remote preamplifier must be used with this sensor.
