Dataq DataView Data Logger DVTH
DataView DVTH Data Logger for Temperature and Humidity
● Logs temperature, humidity, and dew point
● Built-in real time text and graphical display
● Measures 10 °C ~ 65 °C and 0 ~ 99% RH (non-condensing)
● Stand-alone or PC-connected operation
● Onboard sample memory stores up to 43,344 samples
● Battery-powered with three (3) standard AA batteries
● Built-in USB port for configuration, calibration, and data download
● Export to Microsoft Excel®
The Dataq DataView DVTH is a self-contained, precision data logger for recording the temperature and relative humidity of the surrounding environment. The DVTH can store up to 43,344 temperature samples, or up to 21,672 of both temperature and relative humidity samples, and it also computes and displays Dew Point Temperature in real time. The data logger’s sampling interval may be set from one second to 18 hours in one-second increments. A major feature of the DVTH is a built-in display that provides a real time graphic plot of temperature and RH that even allows you to scroll through the recording history without interrupting the current recording session. Two text summary screens may also be enabled. One displays the current RH, temperature, and dew point in large, easy-to-read block characters. A second displays logging information such as the sampling rate, the number of samples recorded, the length of the current recording and the amount of time left for recording. The Dataq DataView DVTH data logger can be provided with a NIST calibration certificate, and also features a tamper-proof design to make it a solution for highly regulated applications.
Versatile with many applications
Refrigerators; freezers; wine storage; medical facilities; greenhouses; florists; museums; document storage/archive facilities; laboratories; cigar humidors; many more.
Wide measurement range
Temperature operating range is –10 to 65°C (15 to 150°F); RH range is 0 to 99% non-condensing.
Built-in text and graphic display
Allows instant visual confirmation of current temperature, dew point, and RH, along with real time and historical trends and excursions.
On-board sample memory
Allows all data to be recorded over extended periods for later recall through the built-in display or by PC download.
Extended sampling intervals
Programmable sampling intervals range from one second to 18 hours in one second increments for very fine and flexible time resolution.
Programmable alarm thresholds
Over/under alarms may be enabled for both temperature and RH to flag out-of-range conditions.
NIST traceable option
The Dataq DataView Data Logger DVTH can be provided with an NIST traceable certificate to satisfy contractual or regulatory requirements.
Delayed start selection
Allows the DVTH to initiate logging on its own at a specific date and time.
Built-in real time clock
All acquired data is time and date stamped.
Tamper-proof recordings
Unique serial number and session counter combine to ensure tamper-proof data recordings that satisfy the most demanding requirements.
Battery operation
Low-power operation runs on three internal lithium or alkaline AA cells (included) for at least one year depending upon usage.
Automatic shutdown
When not configured to actively log data the DVTH will shut itself down after one hour to conserve battery power.
Memory rollover selection
Configure the DVTH to either stop recording when the memory is full, or rollover to overwrite the earliest recorded data.
Field-adjustable calibration
Allows you to calibrate the DVTH yourself, or we can recalibrate the instrument for a nominal charge.
Integrated USB port
Connect the DVTH to any Windows-based PC for configuration, calibration, or data download.
PC software
Provided Windows-based software allows DVTH configuration, calibration, download, and data graphical review and analysis.
Microsoft Excel export
Built-in data file translator allows data export to Microsoft Excel for further analysis and report generation.
