2335 - Precision Digital pHmeter

The ultimate hi-resolution pH-meter

2335The AMEL Model 2335 Digital pH Meter offers a new dimension to the quality, accuracy, and reliability normally associated with instruments produced by AMEL.

The newly developed microprocessor offers quality features such as:

  1. Simplicity of use
  2. High level of flexibility
  3. Unrivalled performance
  4. Exceptional price to performance ratio

The Model 2335 offers high performance in any application, whether it be precise laboratory use, routine measurements in various industrial fields, or in education.

The large display provides the user with total control of all parameters, and the intuitive keyboard permits rapid calibration checks when following the step by step instructions given in the menu.

Usb connection is provided for printing results and software control.
