T&D Data Loggers with a high precision temp-humidity sensor have been updated from "-H" type to "-S" type models. The "S" type models come with one of the following new high precision temp-humidity sensor: SHA-3151 or SHB-3101, which have improved environmental resistance (i.e. improved accuracy when measuring in a high humidity environment, or in an environment that is exposed to corrosive gases and/or organic solvents). This makes consistent and accurate humidity measurement possible even in difficult conditions.
