Can we handle all the following sensors with one CR6 data logger without using the multiplexer? (Cosider the number of units of sensors) 

• CS215 temperature and Humidity probe (one unit)
• CS106 barometer (one unit)
• 034B Wind Sentry Annemometer (one unit)
• TE525MM Tipping Bucket (one unit)
• NR01 Net Radiaometer (one unit)
• 255-100 Evaporation Gauge  (three units)
• CS650 Soil Moisture Sensor (two units)
• 109 Thermometer for water temperature ( three units)

Hi,

It really seems so. But  you can not use the differential measure for the net radiomenter.

Maybe I'm missing something but you may need to double check this. I don't see the three 255-100 evaporation pans in the program. From the manual I was looking at, this is a half bridge measurement. With these 3 measurements in the sensor list, the NR01 will not fit.

FYI, I checked this on a CR1000X and it fits nicely, but again, only if the NR01 measurements are SE. Can you switch to a CR1000X?

Dear Sir,

Many thanks for your feedback and consideration.

Best Regards,

Bushry

Hi

sorry!

I made confusion between the net radiometer and the 4-element model.
Excellent solution for CR1000X
