Again another major advancement in the p H field is developed by Beckman—and available exclusively with Beckman pH Equip>m e n t . . . the Automatic Multiple Glass Electrode Recording Switelm I
WHAT IT DOES: This switch makes possible automatic and continuous pH recording from as many as SIX different electrode stations, using only one Beckman pH Indicator and one multiple recording instrument. Thus, from a single indicator and recorder installation, you can maintain automatic and continuous check over the pH in as many as six different operations o f your plant processes. HOW IT WORKS: The switch is completely automatic in operation and there's noth-
The Automatic Multi-Electrode Switch is another Beckman pH development of major importance to modern industrial control operations. Like the Beckman High pH Electrode, the Beckman High Temperature Electrode and other Beckman advancements, this new pH development is available in Beckman Equipment exclusively!
ing to require the operator's attention at any time. Automatically the switch connects the first set of electrodes into the automatic pH indicator and gives time for the r e corder to print the pH reading from this set of electrodes on the chart. Then the switch automatically disconnects the first station and connects in the next electrode station for recording its pH reading . . . repeating this operation on as many as six electrode stations, and then repeating the cycle over again, continuously, without any attention from the operator.
Now, more than ever, Beckman is the ONLY make of pH equip· ment incorporating ALL the modern pH advancements!
