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.

Specification
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.
