The PCE-THB 38 Environmental Meter is ideal for detecting and digitally displaying humidity, temperature and barometric pressure. Temperature is measured by an RTD sensor and air humidity is measured by a highly repeatable, capacitive sensor. All products are test instruments, and the Environmental Meter is sent out manufacturer calibrated. An ISO certification is available optionally.
