(3) adopt photo-electricity coupling no power pulse output, and indication using electricity by led, and can realize collecting reading meter so as to control using electricity and management. It is used for measuring active energy power loss in frequency 50 hz or 60 hz single phase ac electricity net and which is installed in meter box indoors or outdoors. 44.5x28.5x39cm/carton

This compact tester features a large easy-to-read LCD. Unlike other pH testers, the pH electrode can be interchanged with any pH electrode of different size and shape. This allows you to use application specific electrodes and saves the cost of a new meter when it is finally necessary to replace an exhausted electrode. The tester is fast, accurate, lightweight. Testing pH has never been easier!
