CLASS 120 KISTOCK DATA LOGGERS

Overview

The Sauermann KISTOCK KT120 and KH120 are data loggers designed for measuring and recording temperature and humidity.

Operating Conditions, Storage, and Battery

• Operating Temperature: KT120: -40 to +70 °C; KH120: -20 to +70 °C
• Protection: KT120: IP65; KH120: IP20
• Storage Temperature: -40 to +85 °C
• Battery Power Supply: 1 x CR2450 button battery

Display

The device features a digital display with various indicators:

• END: Indicates the dataset is finished.
• REC (flashing): Indicates a value is being recorded; flashing means the dataset has not yet started.
• Storage Capacity Indicators:
  • Slowly flashing: Dataset is between 80% and 90% of storage capacity.
  • Quickly flashing: Dataset is between 90% and 100% of storage capacity.
  • Constant: Storage capacity is full.
• Max/Min Values: The displayed values are the recorded maximum/minimum values for the displayed channels.
• Alarm Indicator: Indicates the alarm action type (rising or falling action).
• BAT (constant): Indicates that the batteries have to be replaced.
• Channel Number: Indicates the channel number which is measuring.

Units displayed can be: °C (Celsius), °F (Fahrenheit), %RH (Relative humidity for KH 120).

Recorder Function

The KISTOCK allows recording measured values instantaneously at a predefined interval, or continuously via loop recording.

Dataset Start Types:

• Delayed start (with predefined date and time).
• Start via software.
• Start via push-button.

Dataset Stop Types:

• According to a predefined date and time (if started the same way).
• According to a recording duration.
• According to a predefined number of recording points.
• When storage capacity is full.
• Via the "Stop" option in the software.
• By holding the "OK" key for approximately 5 seconds (if previously activated by software).

Mounting

The KISTOCK data loggers feature magnetic mounting for easy installation.
