Simultaneous readout of pH, conductivity or TDS and temperature
Fully featured pH and Conductivity meterss in a single, hand held unit
Automatic or Manual calibration of both functions
Power on self-check routine
Environmentally protected case to IP65
Supplied with FREE Carry case
The Model 430 is designed to readily withstand the rigours of portable analysis, while reliably measuring pH and conductivity in a simple and professional manner.
This product allows the simultaneous readout of pH, conductivity or TDS and temperature using the 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 with manual override. Conductivity calibration can be performed 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.
An indication of battery life is also permanently shown on the display. An automatic switch off facility helps to conserve battery life.
The Model 430 is housed in a robust, ergonomically designed case that is environmentally protected to IP65. This product is ideal for field or any portable situation.

This product is currently unavailable, due to the manufacturer having delays in external testing. This product should be available again in January 2015.
In the meantime, we recommend the HI-8424N Waterproof pH Meter as the closest replacement.
