Calendar Clock
•
24 Hour Calendar Clock.
•
Tests for valid day of the month when setting (eg. 31/09/99 is not valid).
•
Adjusts for leap years.
Peristaltic Pumps
•
The
easyCHEM 770
has 2 x built-in Peristaltic Pumps for ORP and pH control.
•
Chemical resistant Santoprene pump tubing.
•
Standard small pump tubing produces 1.6 Litres / Hour
Large pump tubing produces 5 Litres / Hour
•
An optional fast pump motor is available, which produces 15 Litres / Hour with large tubing
only.
