- General Description
The 873EC Analyzer measures the conductivity of aqueous solutions. Its measurement display
may be read in either µS/cm, mS/cm, or percent (%). Solution temperature is also measured by
the 873EC for automatic temperature compensation and may be displayed whenever the user
wants.
It provides an isolated output signal proportional to the measurement for transmission to an
external receiver. The plastic panel-mounted analyzer transmits one output signal only, while the
metal enclosure analyzers can transmit two output signals.
Instrument Features
Described below are some of the features of the 873EC Electrochemical Analyzer:
♦ Plastic or Metal NEMA 4X Enclosure
♦ Dual Alarms
♦ Dual Isolated Analog Outputs on Metal Enclosure
♦ EEPROM Memory
♦ Instrument Security Code
♦ Hazardous Area Classification (Metal Units)
♦ Front Panel Display
♦ Front Panel Keypad
♦ Application Flexibility
♦ Storm Door Option
Enclosures
The plastic enclosure is intended for panel mounting in general purpose locations, and mounts in
1/4 DIN size panel cutout. It meets the enclosure ratings of NEMA 1, CSA Enclosure 1, and IEC
Degree of Protection IP-45.
The metal enclosure is intended for field locations and may be either panel, pipe, or surface
mounted. The housing is extruded aluminum coated with a tough epoxy-based paint. The
enclosure is watertight, dusttight, and corrosion-resistant, meeting the enclosure ratings of
NEMA 4X, CSA Enclosure 4X, and IEC Degree of Protection IP-65. The unit fits in a
92 x 92 mm (3.6 x 3.6 in) panel cutout (1/4 DIN size). The field-mounted enclosure provides
protection against radio frequency interference (RFI) and electromagnetic interference (EMI). - Email:fengyun862@gmail / 2804538582@qq.com
