Jenway Enterprise 430 Portable pH/Conductivity Meter
MAIN FEATURES and BENEFITS
Simultaneous readout of pH, conductivity or TDS and temperature
Combined pH and conductivity probe assembly
with integral ATC sensor - replaceable pH electrode
Easy to read with backlit liquid crystal display
1 or 2 point pH calibration with
auto buffer recognition (manual override)
Direct conductivity calibration on standard solutions
or by direct cell constant entry
Rugged and robust design
Now supplied with free carrying case
The Model 430 is designed to readily withstand the rigours of portable analysis, whilst reliably measuring pH and conductivity in a simple and professional manner. This product uniquely allows the simultaneous readout of pH, conductivity or TDS and temperature using a custom backlit liquid crystal display. Calibration errors are clearly indicated, together with the parameter in error.
The 430 offers 1 or 2 point pH calibration and automatic buffer recognition (4.00, 7.00, 9.22 and 10.05) with a manual override facility. Conductivity calibration can be performed with direct calibration on standard solutions or by direct cell constant entry. The conductivity/TDS range is automatically selected for optimum resolution and temperature compensated using an adjustable temperature coefficient.
The 430 is supplied with a combined pH and conductivity probe assembly (a temperature sensor is also incorporated to provide automatic temperature compensation). The probe connects to the instrument via a single mini-DIN connector for operator convenience.
The instrument is housed in a robust, ergonomically designed case that is environmentally protected to IP67 standards.
An automatic switch off facility helps to conserve battery life, with low battery indication being shown on the display.
