All units feature a digital input which can be used as an event trigger or as a counter input enabling counts of up to 65535 per period to be recorded.

Powered by its own, user replaceable, internal battery that has a typical life in excess of 6 years, up to 128,000 readings can be recorded at intervals from 1 second to 24 hours.

The SL7000 features unprecedented accuracy, combining our extensive knowledge of instrumentation precision with data logging technology. High end resolution of 16 Bit for all universal inputs and a modular build ensures that the unit is competitively priced whatever the application.

An on-board LCD display (Optional) shows selected channel information and integral LED displays provide immediate scanning and alarm status information.

The logger can be set to start immediate, start on an event (either a trigger event or the exercising of an external digital input) or start with the application of an external magnet (Provided). This feature enables loggers to be set up in advance of the mission by a supervisor and to be launched at the start of the journey / log period by an operator.

The SL700 series data loggers are compact, self powered data loggers. Each data logger is battery powered for up to 10 years. They have three memory options that will store either 21500, 87000 or 1 million readings at sample rates from 45mS* to 8 hours. The SL700 series data loggers can be used to measure temperature via thermistor, thermocouple or Pt100 sensors, relative humidity, gauge and absolute pressure and pulse signals.

All members of the SL700 data loggers can be used in conjunction with the SL-ACC19 GSM modem which allows the data loggers to be mounted in either remote or mobile installations. Then, using a conventional modem, it is possible to dial up the remote site and view current operating conditions as well as downloading the stored readings. It is also possible for the data logger to dial out or send a SMS text message in the event of an alarm condition. All SL700 seriesdata loggers have a 10 year battery warranty and a 3 year electronics part warranty.

The SL400 system is a radio based wireless telemetry system. Ideal for retro fitting a monitoring system into an existing installation with minimum downtime and cost.

The SL400 system comprises of remote radio transmitters that measure temperature, relative humidity, low differential pressure, mA or voltage signals and periodically transmits the values back to a receiving base station. The radio transmitters operate on the worldwide, license free frequency and have an output power of only 10mW which does not interfere with other sensitive electronic equipment but allows up to 1000m transmission range.

The SL400 base stations can now be supplied with Ethernet connectivity. This means that there is no longer a restriction on the distance from the transmitters to the base station.
The SL400-ETHERNET base station can be connected to your existing Ethernet network in a convenient location to pick up the relevant transmissions and the data passed over your network.

The software supports up to 20 base stations.

The SL50R Button Reader™ interfaces to the RS232 or 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 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.

Three self contained, battery powered, USB data loggers. The SL51USB and SL52USB are single channel temperature data loggers. The SL54USB records temperature and relative humidity. All three 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. Depending on the model chosen, 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.

All three USB 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.

Each of the three models have specific advantages:

SL51USB - Lowest cost, stores 2048 readings and ±1°C accuracy

SL52USB - Up to 8192 readings, ±0.5°C accuracy and faster sample rates

SL54USB - Temperature & relative humidity version
The SL52USB also has a "start when alarm" function which inhibits data logging until the data logger has been in an alarm condition. Ideal for temperature related fault finding.
