Amplify ISE, pH or Redox electrode mV signals to allow longer cables between electrode and computer interface or data-acquisition system – up to 50m.

Three types:

• TRA-IS1-B, For one electrode, either as combination or with a separate reference electrode. Battery-powered – particularly for field use. 
• LAB-EA4-C. For four electrodes simultaneously with a common reference system in one vessel or in four separate vessels each with own reference 
• LAB-EA4-CI As above but with four, separate, isolated channels to avoid ground loops .
