HT50 USB Humidity and Temperature Data Logger Manual V1.1
USB Humidity and Temperature
Data Logger with Build-in IRT
Model: HT50
Introduction
HT50 USB humidity and temperature data logger with build-in IRT is designed to record room
temperature and humidity of places such as medium/small warehouses and computer rooms. The
build-in IRT is designed to measure surface temperature of objects. The logger automatically
keeps tracking temperature and humidity variations daily; and record both readings according to
the rate set by users. Real time ambient temperature/humidity readings, IRT readings and
recording status will be displayed on the LCD. The portable size and user friendly interface makes
it easy to use and install.
Features
1. Real time ambient temperature/humidity and recording status will be displayed on the LCD
screen; Measurement range: temperature: -20℃-70℃; Humidity: 0-100%RH
2. Measure surface temperature using the build-in infrared thermometer, Measuring range: -20℃
-250℃;
3. Internal EERROM memory, tracks and records 5000 set temperature/humidity readings; battery
life at most 1 year; data recorded stays in the memory until the next reset-up using the included
software. Users are allowed to download data from the logger to the computer.
4. Data transmission via USB link
5. Setup high and low alarm limit, measuring units, sampling rate, start time etc from the included
software.
6. Time synchronization when connected to PC.
7. The included software also supports data analysis, recorded data can be export into a .txt file for
further analysis. The temperature and humidity data can also be displayed in a curve graph which
can be printed and archived.

Function Buttons
MEAS button:
——Press to measure object’s surface temperature using the IRT, and the device will switch to
IRT mode;
——Release to finish the IRT measuring, the last reading will be hold on LCD screen. The logger
will exit from IRT mode if this button is not pressed again in 10 seconds; press again to start
another IRT measurement.
Set button:
Short press this button:
——Turn on the LCD screen when it is off
——While the LCD is on, switch between the four display mode: temperature readings, humidity
readings, mix ratio and working status
Working status has 4 states below:
Log: Indicates the logger is in recording mode
―――: Indicates the logger is in standby mode, in this mode, the device can only display current
ambient temperature and humidity without recording them
FUL: Indicates the logger’s memory is full, recording stopped automatically; current ambient
temperature, humidity and IRT readings can be displayed
CON: logger has not been configured from software, a configuration is needed to set up relative
parameters
Press and hold for 3 seconds to start/stop recording, IRT readings will not be recorded, LCD
switches to working status mode; release the button, LCD switches to previous mode.
Sto button:
Short press this button:
——Turn on the LCD screen when it is off
——While the LCD is on, in temperature display mode, press to switch temperature units

Press and hold for 3 seconds to start/stop recording, IRT readings will also be recorded, LCD
switches to working status mode; release the button, LCD switches to previous mode.
Operation Instructions
1. Battery Install
HT50 uses DC3.6V lithium battery. Pull out the battery compartment ,place the battery at right
polarity, then put back the compartment.
NOTE: If the battery is removed before setup from software or during recording,
the logger has to be reconfigured from software before reactivated, otherwise, devise will
stay in standby mode. In this case, press Set briefly to display working status, “CON” will
be displayed. The former daras were saved. The USB port powers the device while the
logger is connected to a PC. In this case, the battery can be removed without interrupting
the recording. But if pull out the unit from PC, the battery must be installed, then set
again.
2. Software Install
Please install the included driver and software. The software manual with the detailed
installation steps is inside the CD.
3. Activate/Deactivate the Logger
After finish installing the software, plug the logger in the USB port of the PC, set up the logger
according to the software manual. After “Setup” ,hold SET or STO buttons for 3 seconds to
activate/deactivate the logger.
4. Collect and Record Data
HT50 has an internal EEPROM memory. Users are allowed to set up recording rate using the
included software; the logger will collect and record temperature/humidity data automatically.
Press the button to check current ambient humidity, temperature and recording status. When
recording status is displayed, “Log” means the logger is recording data; “FUL” means the
memory is full, recording is stopped.
5. Export Data
Data collected by HT50 can be download to the computer using the included software, and
saved as a *.txt file. This file will list all the data recorded in the logger memory for further
analysis. For detailed steps, please refer to the software manual.
