Drift
a
(dry)
a. ASTM drift tests require a temperature change of less than 2 °C/hour (3.6 °F/hour) over a one hour period. Larger
ambient changes will result in larger drift. Better drift performance depends on better control of temperature fluctuations.
To realize the highest performance, minimize the frequency and the amplitude of temperature changes to below
1 °C/hour (1.8 °F/hour). Turbulences around one minute or less can be ignored.

Feature Specification
Integrated leak management Leak sensors, as standard, and safe leak handling. Drip
trays direct all leaks to the front of the instrument, and then
into the waste line.
Operating flow rate range 0.010 to 4.000 mL/min, in 0.001 mL increments.
Maximum operating pressure 41,369 kPa (413 bar, 6000 psi) up to 3.25 mL/min.
pH range pH 2 to 12.
Unattended operation Leak sensors, full 96-hour diagnostic data display through
the console software.
