Automated
Designed to automatically monitor a variety of instruments including vibrating wire gages
General Purpose Dataloggers
The Canary Systems® MCLOG is our standard general purpose wireless datalogger. It is designed to automatically monitor a wide variety of instrument types, including SDI-12, vibrating wire, flowmeters, linear potentiometers and 4-20mA, among others.
The MCLOG contains a CR300 series datalogger with a 900 MHz RF401 radios. The MCLOG is available with a number of data acquisition and power supply options, optimized by Canary Systems engineers for a variety of intended applications.
Battery & Enclosure
Power supply options
- AC adaptor
- 20W solar panel including Sunsaver charge controller
- rechargeable lead-acid battery
(12VDC – 12AHr, 24AHr) - replaceable alkaline battery pack
