The Merlin data logger is a compact, low power multi channel device capable of handling a range of analogue and serial inputs and logging data at speeds of up to 50Hz. It has 10 analogue inputs with a 0-5V input range. Seven of these inputs can also be configured to read frequency inputs from flow meters. The unit also has a serial RS485 port for connection to Keller digital pressure sensors, and other serial devices. The logger also has a high contrast backlit LCD display for viewing real time readings, with the option of a second display where large format text is required.

The MSR 145WD is a miniature data logger equipped with a Bluetooth Low Energy wireless radio link and OLED graphic display. The logger has options for monitoring temperature, humidity, pressure, 3-axis accelerometer (X, Y and Z axes) and light with internal and external sensors. The units are available with a 230mAh or 900mAh battery and in an IP60 or IP67 housings. The BLE connection allows for a radio link of up to 10m using a 2.4GHz frequency and multiple MSR145WD loggers can be connected at once.

The MSR 145W2D is a miniature data logger equipped with an OLED graphic display and WiFi/WLAN network connectivity. The logger has options for monitoring temperature, humidity, pressure, 3-axis accelerometer (X, Y and Z axes) and light with internal and external sensors. The units are available with a 230mAh or 900mAh battery and in an IP60 or waterproof IP67 housings. The WiFi/WLAN can be integrated into an existing WiFi network, or via an access point and the units range can be extended using standard WiFi extenders.

The MSR 147WD is a miniature data logger with plug-in sensors. The loggers also comes equipped with a Bluetooth Low Energy wireless radio link and OLED graphic display. The logger has options for monitoring temperature, humidity external sensors, plus internal air pressure and 3-axis accelerometer (X, Y and Z axes). The units are available with a 230mAh battery in an IP60 or IP67 housings. The BLE connection allows for a radio link of up to 10m using a 2.4GHz frequency and multiple MSR147WD loggers can be connected at once. The Bluetooth connection allows for the measured data to your smartphone and to transfer it to the MSR SmartCloud.

The MSR147W2D is a miniature data logger equipped with an OLED graphic display and WiFi/WLAN network connectivity. The logger has options for monitoring up to 5 plug-in temperature or humidity sensors, plus internal pressure and 3-axis accelerometer (X, Y and Z axes). The units are available with a 230mAh battery and in an IP60 or waterproof IP67 housings. The WiFi/WLAN can be integrated into an existing WiFi network, or via an access point and the units range can be extended using standard WiFi extenders.

The MSR255 is a robust multi-talent data logger with an integrated LCD screen. The unit has the option of measuring temperature, humidity, air pressure and light sensors with both internal and external sensors together with the option of a 3-axis accelerometer (X, Y and Z axes). The units are currently available in a standard IP 60, and will shortly be available in a waterproof IP67, housings. The MSR255 has an internal memory for over 2 million readings and uses an internal 2300mAh rechargeable lithium polymer battery.
