ML-017 – standalone data logger

Home » ML-017

Low power standalone data logger

The ML-017 data logger is similar to the ML-417 however this measurement devices does not include the cellular communication abilities. Making it a cost efficient solution for on-premises data logging or as a stand alone data logging device.

Equipped with an ML-OA-WIFI option board this device can also de used for wireless data logging via WiFi.

outdoor data logger

Our multi-purpose data logger is customizable for any application

Available with several power provisions (e.g. batteries, DC input, solar panel input etc.)

2 current loop inputs, 2 voltage inputs, 1 potentiometer input and 3 digital inputs.

Provided with a serial port to capture measurements from ASCII, MODBUS, NMEA or SDI-12 compatible sensors

Up to 8 mathematical channels are available to calculate meaningful engineering values derived from sensor input values

Cost efficient data logging solution

A self providing monitoring station

When equipped with the integrated solar panel and ML-OA-WIFI option board a complete self providing wireless monitoring station can be arranged, all you need is a logger and applicable sensor(s). This self providing data logger is costs saving, because you don’t need: a) solar panels, b) big batteries and c) encapsulating cabinet.
