How to Use
Connection of Probe:
While the main unit is turned off, insert the connector of the probe straight into
the probe connector on the main unit so that an arrow mark on the probe faces
frontward. Turn the nut on the probe next until the probe is fixed.
Do not turn black elastic parts.
Refer to the manual for the main unit of SK-110TRH-B as well.
Sensor Filter:
An optional sensor filter sold separately can cover S110TRH-10/20 to resist a dusty environment.
Cautions
To use the probes for SK-110TRH-B properly, follow the instructions below.
 Do not use the probe in any non-standard atmosphere or submerged in liquids.
 Do not touch the humidity sensor with hands.
 Do not store in bubble buffers or antistatic bags, which have a distinctive color such as blue, pink, or rose pink in
general. It may damage the humidity sensor.
 If the probe gets condensed with moisture, turn the power off immediately and dry it naturally under room temperature
before use.
 Be sure not to burn yourself when measuring high temperature.
 Do not wet, give a heavy shock to, forcibly pull, disassemble, or customize the probe.
 For repair or calibration, contact us or a retailer from which you have purchased.

Accessory Instruction manual
* Probes are consumables which deteriorate over time. Thus, a
regular recalibration and replacement are advised. Especially, the
accuracy of the humidity sensor worsens for 0.5%rh per year even in
a good condition.
** As for SK-110TRH-30, its cable moves into the telescoping probe
when the probe is extended. Therefore, the total length of the cable
and the probe is always around 1.7 m.
