SL64TH / SL64TH-A Miniature Temperature and Humidity Data Logger With High Accuracy Option
The next generation of miniature temperature and relative humidity data loggers that measures from -20°C to +70°C (-4°F to +158°F) and 0 to 100% relative humidity. With a temperature accuracy of ±0.2°C / ±0.4°F and a relative humidity accuracy of ±3.5%. Compared to the SL50 series data loggers, all dLog data loggers have a larger memory, improved accuracy, non-volatile memory, so the data can be downloaded should the battery be depleted and a remaining battery life indicator.
All dLog data loggers communicate with the USB-powered NFC reader. The same reader can be used with all members of the dLog family. The TempIT5 software also has a remaining battery life feature, and the stored data can still be downloaded even if the data logger battery is dead.
The SL64TH-A is supplied with a UKAS 17025 traceable calibration certificate and improved temperature and relative humidity accuracies.
Starter kits are available with either two or five SL64TH or two or five SL64TH-A temperature data loggers, USB interface cable and the TempIT5-PRO software.

description
The SL64TH & SL64TH-A can be programmed to take readings from once every 3 seconds to once every 24 hours. The data loggers can be programmed to start logging immediately, on a specific time and date, if the measured temperature goes above or below preprogrammed limits or even, after specific time period and also above or below preprogrammed temperature limits.
Starter kits are available with either TWO or FIVE temperature data loggers, the USB Interface and the TempIT5-PRO software.
The SL64TH is a self contained, multiple use, small temperature and relative humidity data logger with the ability to record up to 9,500 temperature and humidity readings over the temperature range of -20°C to +70°C and 0 to 100% RH with an accuracy of ±0.2°C and 3.5%.
The SL64TH-A is supplied with a UKAS Traceable calibration certificate and an improved accuracy of ±0.1°C ±0.1% of calibrated span (minimum span of 20°C). The default calibration points are 0°C, +20°C and +40°C and 21% RH, 43% RH and 75% RH at an ambiet temperature of 21°C. Contact us if you require different calibration points. You can choose any three temperature points from -19°C to +69°C and there must a a difference of 20°C or more between the highest and lowest calibration points. For the humidity calibration, you can choose three humidity points from 10% to 90% at ambient temperature from +10°C to +40°C. It is possible to have more than three calibration points but please contact us for more information.
Being only 22mm in diameter and 11mm thick, the SL64TH is an incredibly small temperature data logger, ideal for use in confined spaces.
The memory can hold up to 9,500 readings and can be cleared at the start of each data logging session, allowing the data logger to be reused over and over.
The SL60-READER NFC interface is required to connect to the USB port of the computer and is compatible with the user friendly, and free of charge, TempIT5-Lite operating software. This enables the miniature temperature data logger to be set up and the readings downloaded from the data logger and displayed in a graphical format. Data can also be saved and retrieved at a later time. The software can be upgraded to TempIT5-Pro which provides various additional features such as data table view, export data to spreadsheet, graph annotations, and automated MKT, F0, A0 and PU calculations.
The NFC USB Interface lead and software are not included with this temperature data logger unless you purchase one or more of the starter kits but you can find details of these and other related items in the accessories section.
