a.
While the temperature repeatability is constant for the whole temperature range (from 0 °C to 95 °C), the temperature
accuracy is not constant for the whole range. For temperatures above 90 °C, the temperature accuracy is typically
between 0.01 °C and 0.05 °C.

c.
Cooling down further than 20 °C (68 °F) below ambient temperature only with external cooling using the cooling kit
d.
For the measuring cell together with the injection adapters DMA/CarboQC (Mat. No. 19680) in the temperature range
of 0 to 50 °C (32 to 122 °F). For temperatures higher than 50 °C (122 °F), the maximum allowed pressure is 5 bar
(72.5 psi). See also Appendix C.2.
