New data for “Suitable for monitoring” has been added to the filters on the -25°C to -45°C freezers page. If your work requires independent temperature monitoring of either chamber or core temperatures, consider selecting "Yes" for this attribute. Most inexpensive spark free units do not offer fan circulation and this can cause significant temperature gradients within the chamber. Units we consider suitable for temperature monitoring have temperature variances of less than 0.1°C.
