HTD ThermaData, Humidity & Temperature Logger, LCD Display, Internal Sensors
- visual display of high & low alarm status
- records up to a maximum of 16,000 readings
- simple visual inspection shows if limits exceeded
The new humidity and temperature ThermaData loggers are portable data-loggers that measure and record both temperature and relative humidity (%rh) over the range of -20 to +85°C and 0 to 100% RH.
At programmable intervals, the loggers will record simultaneously both temperature and humidity, recording up to a maximum of 16,000 readings (8,000 humidity and 8,000 temperature).
The ThermaData® HTD humidity logger has a built-in LCD display that shows both temperature and humidity levels and includes internal humidity and temperature sensors.
Each logger incorporates a red and green LED, the flashing green LED indicates that the logger is active/logging and the flashing red LED indicates that your customised pre-set alarms have been exceeded.
The humidity and temperature ThermaData loggers are suitable for a diverse range of applications which include HVAC climate monitoring, QA monitoring of storage areas etc.
Attention humidity sensor:
The humidity sensors housed in these products are susceptible to contamination from pollutants such as solvents and exposure to saturated air and therefore are not covered under the 2 year warranty. Furthermore it is expected that the sensor’s readings will drift by up to 0.5% per year.
ThermaData logger software:
The ThermaData logger is connected to a PC via a USB cradle. By clicking the relevant icon the data can be downloaded and displayed either as a graph, table or summary. The information can be analysed by zooming in, storing to disc or exporting in Excel (.xls) or as a text (.txt) file to other software packages.
The ThermaData Studio software incorporates several useful functions, including the ability to display two traces on a graph, the trace colours are user selectable. All files can be viewed as thumbnail icons for easy identification.
The ThermaData Studio software will work equally with all ThermaData loggers. The software is both powerful and sophisticated, yet user-friendly enabling temperature data to be organised and analysed to provide management information. The software allows the user to programme the logging sample/interval rate (0.1 to 255 minutes), the real-time clock, °C or °F, delayed start (maximum 23 hours, 59 minutes and 59 seconds) or select a magnetic start option. It is also possible to include a 32-character user ID for each logger.
By selecting continuous logging in the software options, it is possible to start the ThermaData logger only once and never have to reset its parameters again, even if downloaded regularly. Unlike most low cost loggers, the ThermaData logger will continue recording during and after downloading the data. The ThermaData Studio software is supplied with each USB cradle.
Please note: when initially ordering loggers it is necessary to order at least one ThermaData logger cradle.
