Description
■ Notice:
Be sure to purchase chart paper with a temperature range of −15 to 40°C, humidity range of 0 to 100%rh. Confirm the temperature range with care in advance as we also offer paper of different ranges.
Feature
■ Sigma II Thermohygrograph series is an ultimate gatewatcher of temperature and humidity at sensitive professional places such as factories of semiconductors or LSI, experimental chambers, and pharmaceutical warehouses.
Record on a chart roll is visible through the transparent cover made of acrylic glass. Not only it is easy to carry by holding the handle on the top, but also turning the same handle makes the cover open to enable easy maintenance.
Dustproof paper suitable for a clean room or a hospital and normal paper are selectable. Three different intervals before exchanging paper determined by an internal quartz clock are available: 1 day, 7 days, and 32 days.
