SPEC SHEET
CDH-420
The CDH-420 conductivity/ TDS/resistivity/salinity and temperature meter is a fully waterproof and rugged handheld meter suitable for use in industrial plants and job sites with harsh environments. The meter is also well suited for use in laboratory environments. Built to meet the IP66 waterproof design the meter will actually float if accidentally dropped into water.
The unit combines a fully sealed tactile keypad and menu driven operation for mode selection, diagnosis and measurement routines to provide full flexibility and ease of use. The setup menu allows access to all user defined options. The menu is three tiered, allowing for set-up of calibration parameters, instrument parameters, such as languages (English, French, German, Italian, Spanish and Swedish), temperature and auto shut off time delay.
The CDH-420 display will simultaneously display temperature, conductivity, TDS or resistivity values. The meter can also store up to 100 data points and recall these onto the instruments display. In addition, the user has the option of downloading results to a PC by utilizing the integral bi-directional RS-232 infrared link with the optional interface cradle and software.
The CDH-420 is supplied complete with waterproof meter, waterproof sensor, batteries and complete operator's manual.
