The TR-73U has all the great features of temperature and humidity data logger plus a third channel for monitoring and recording ambient pressure.
This compact unit has a large 4 digit LCD display for reading current values that can be set to show any single channel, or all three on a rotating basis. The logger can store up to 8,000 sample triplets,
operates on a single AA battery and incorporates a USB interface for rapid data downloading.
The TR-73U ships complete with software, sensor and cable included.

3 Measurement and Recording
TR-73U Thermo Recorders are data loggers capable of measuring, displaying and recording temperature, humidity and ambient pressure data.
TR-73U has one temperature, one humidity and one ambient pressure channel.
The data recorded into the TR-73U units can then be downloaded quickly via USB cable to your computer whereby with our exclusive software you can easily process the data into graphs, tables, save to files and/or print it out.
Moreover, it is possible to connect more than one unit at the same time.
Internal Temperature Measuring Range -10°C to 60°C
The external sensor that comes with the TR-73U can measure and record from -10°C to 60°C.
External Temperature Measuring Range 0°C to 50°C
The external sensor that comes with the TR-73U can measure and record from 0°C to 50°C.
Humidity Measurement Range 10% to 95%RH
The external sensor that comes with the TR-73U can measure and record temperature
from 0 to 50°C and humidity from 10 to 95% RH.
Internal Barometric Pressure Measurement Range 750 to 1100 hPa
The internal ambient pressure sensor that comes with the TR-73U can measure and record pressure
from 750 to 1100 hPa.
Large Data Capacity: 8,000 Readings X 3 Channels
Each channel can record up to 8,000 readings; giving you about one year of continuous recording
at a recording interval of 60 minutes.
15 Recording Intervals, 2 Recording Methods
You can select from 15 recording intervals from one second to one hour.
There are also two methods of recording to chose from.
One Time Method: Recording stops when 8,000 readings have been recorded.
Endless Loop Method: When 8,000 readings have been recorded the oldest data is overwritten and recording continues.
Reliable Backup Function
When battery power becomes low a battery life warning will appear on the unit's display indicating that the battery should be changed. If within a short time the battery is changed, measurement and recording will not be interrupted and there will be no data loss. If the battery is not changed the unit will automatically go into SLEEP mode whereby measurement and recording will stop but, due to our
BACK UP FUNCTION, data will not be lost and will remain saved for up to one year.
