...Two in One

All these data loggers can be used to monitor temperature and relative humidity in a wide range of applications. From simple office environment monitoring, through process monitoring and monitoring relative humidity and temperature sensitive products in transit. Some can be configured to accept multiple sensors, like the SL7000 . Wireless environmental monitoring systems for measuring temperature and relative humidity and transmitting the readings back to a central location are available with SL400 e spYdaq systems.

SL54TH and SL54TH-A - Temperature & Relative Humidity Data Logger
The SL54TH is our lowest cost temperature and relative humidity data logger. It is a self contained and self powered with the ability to record up to 8,000 data points. The SL54TH can operate in a temperature range of -20°C to +85°C and up to 100%RH. They are very small (about the same size as a watch battery) which enables them to be inserted into small items and packages. The SL54TH-A is identical to the SL54TH but with an improved relative humidity accuracy of ±2%. The SL50R Button Reader™ interfaces to the USB port of a PC and is totally compatible with the user friendly, TempIT-Lite operating software which enables the logger to be set up and the data read and displayed in graphical format. Data can be stored and retrieved at a later time. The software can be up-graded to TempIT-Pro which provides various additional features such as data table view, export data to spreadsheet, email graphs and automated MKT Calculations etc. The TempIT software also automatically calculates dew point from the measured temperature and relative humidity readings. The SL54TH and SL54TH-A also calculate dew point.

SL54M and SL54M-A - Temperature & Relative Humidity Data Logger
The SL54M temperature and relative humidity data logger is identical in operation to the SL54TH but is supplied with the SL50-ACC02 rubberised holder. The holder makes installation easier, either via the through hole or using the integral magnet. It is a self contained and self powered with the ability to record up to 8,000 data points. The SL54M can operate in a temperature range of -10°C to +50°C and up to 100%RH. The SL54M-A is identical to the SL54M but with an improved relative humidity accuracy of ±2%. The SL50R Button Reader™ interfaces to the USB port of a PC and is totally compatible with the user friendly, TempIT-Lite operating software which enables the logger to be set up and the data read and displayed in graphical format. Data can be stored and retrieved at a later time.

SL54USB and SL54USB-A - Temperature & Relative Humidity USB Data Logger
The SL54USB records temperature and relative humidity. The SL54USB data loggers plug directly into the USB port of the computer for configuration. They are then removed from the USB slot and placed where monitoring is required. When the monitoring is complete, the data logger is placed back in the USB slot for data retrieval. They have the ability to record up to 8,000 data points and have a measuring temperature range of -10°C to +85°C and 0 to 95%RH. The SL54USB data loggers are fully compatible with our user friendly software - TempIT. TempIT-Lite is free of charge and allows the logger to be set up and the data read and displayed in graphical format. Graphs can be stored, printed or retrieved at a later time. TempIT-Lite can be up-graded to TempIT-Pro which provides various additional features such as data table view, export data to spreadsheet, email graphs, F0 and A0 calculations, and automated mean kinetic temperature (MKT) calculations etc.
