Digital Alarm Thermohygrometer
SK-5600TRH
JAN code : 4974425802098
Calibration : Available
JCSS Accredited Calibration : Available
A high-accuracy digital thermohygrometer with sound and light notifications
The internal sensor measures temperature (down to −10°C) and humidity (up to 95%rh) while the 3-meter external probe measures temperature at a remote place (down to −50°C).
Provides sound and light alerts when a measured value exceeds high thresholds or falls below low thresholds.
■ Overview (Japanese audio)
Feature
■ Temperature and humidity displayed in a row
■ Two temperature sources: Internal sensor and external probe
Pressing the key toggles temperature display. (Humidity is measured internally regardless of the probe.)
Using the external probe enables measurement in a harsh environment such as inside a refrigerator or outdoors.
* Do not put the probe underwater.
■ Maximum and minimum values
Pressing the key cycles through current, maximum, and minimum internal/external temperature and humidity.
Maximum and minimum values are reset by key operation or battery replacement.
■ High and low alarm
Provides audible and LED alerts when preset high or low thresholds are exceeded.
Speaker volume can be set larger, smaller, or turned off.
■ Wall mount and desktop use available
Equipped with a hang hole and a foldable stand.
■ Two power supplies
Applicable to USB-C power input in addition to battery, to enable 24/7 monitoring.
* USB-C cable is not included.
