HOBO® RH Sensor Replacement Kit (HUM-RHPCB-3C) Manual
For use with UX100-011A loggers
1 Remove the cap from the logger case with a one quarter turn
counter-clockwise.
2 Pull to remove the RH sensor from the board inside the logger.
Discard the sensor.
3 Wearing gloves or finger cots to prevent contamination or
damage, hold the replacement sensor by the sides of the board
only. Do not touch the actual sensor (the small black square).
Touching the sensor may compromise accuracy. Insert the
connector on the sensor board into the pins on the board in the
logger. Make sure the RH sensor is oriented with the flat part of
the board pointed down (shown on reverse side) and gently insert
the connector into the pins on the logger board.
