What we measure
Each parameter maps to a Whilogger model.
-
Temperature
Shows when limits were exceeded.
-40 to +85 °C (WL42: +80 °C)
-
Relative humidity
Tracks moisture in storage and rooms.
0–95 %RH
-
Pressure
Logged alongside temperature and humidity.
250–1300 mbar
-
Pulse, event and state
Counts pulses, records events and tracks states.
0–30 VDC input
-
Light
Tracks exposure and photoperiods.
Lux and ON/OFF
-
Thermocouple signals
Profiles ovens and process steps.
8 types, up to +1820 °C (probe-dependent)
-
Strain and bridge sensors
Logs force, load and stress.
±32 mVDC
-
Shock
Listed as WL71 Ultra Shock.
Specifications pending
The Whilogger software on your computer
Connect the logger to your computer over USB and work with its data in the Whilogger software.
-
Connect over USB
Type-C on most models, the AUX-to-USB cable on WL1B.
-
Several loggers, one computer
Connect more than one Whilogger and choose which data sets to view.
-
Live readings
WL1B, WL1C, WL21, WL22 and WL23 show readings in real time.
-
Reports and analysis
Graphs, tables and statistics, with CSV or Excel export on models such as WL42, WL51 and WL61.
-
Configuration
Set the logger up from the software, on its own Configuration tab.
How data acquisition works
From a physical quantity to a record you can analyse.
-
1 Physical parameter
Temperature, humidity, pressure, light, a signal or a force.
-
2 Sensor or input
On-board sensor, thermocouple probe, bridge sensor or digital input, depending on the model.
-
3 Whilogger datalogger
Measures in the field, without anyone standing next to it.
-
4 On-board memory
Stores readings on the device: 1,000,000+ logs on models that publish a capacity.
-
5 Data transfer
Logs are read out to a computer over USB.
-
6 Analysis
Graphs, tables and statistics in the Whilogger software. Export options vary by model.
-
Standalone logging
The logger records on its own, with no continuous connection, and the data is retrieved afterwards.
-
Live reading on a computer
WL1B, WL1C, WL21, WL22 and WL23 also show readings in real time while connected to a computer: through the AUX-to-USB cable on WL1B, Type-C on the others.
-
Whilogger Software
Graphs, tables and statistics, with CSV or Excel export on models such as WL42, WL51 and WL61.
Industrial applications
Where logged data answers what a single reading cannot. Available data depends on the logger.
Warehouse and cold storage
Check that storage conditions held, day and night.

Why Whilogger?
What the model pages publish, conditions included.
-
1,000,000+ log capacity
Published on models with a full specification page.
-
Up to 10 years of battery life
Stated under standard settings, so real life depends on configuration. WL51 and WL61 are listed with a long-life battery.
-
USB-powered operation
WL1C, WL21, WL22 and WL23 can run from USB without a battery.
-
Four start modes
On many models. WL1C, for example, starts on a schedule, on a threshold, by button or over USB.
-
Software for analysis
Graphs, tables and statistics, with CSV or Excel export on models such as WL42, WL51 and WL61.
-
Feedback in the field
An LED alarm indicator on most models, and manual logging from the device button on several.
The figures on this page are measurement ranges, not accuracy. For accuracy, check the datasheet of the model you are considering.
