Good morning, i would like to know how many probes are included in the instrument? in the second image i see two probes, could i send a real-time imag

Thank you for your question. The full set includes: Complete with 6 x AA batteries, SD card, hard carrying case, sample buffers, mini pH electrode (60120B), and Thermistor temperature probe (850188)

Can this perform orp readings without orp electrode? or do we have to buy 67500b standard orp electrode additionally? if so can you offer that as well

Yes, you would need to order the orp probe to measure the orp.

Is this unit capable of continuous immersion logging of typical drinking water to SD card? We'll calibrate every 24 hours, but weekly is better

Thank you so much for your interest in our products. Yes, the SDL100 is capable to datalog information from 1 second to almost 9 hours. All this data will be saved on the SD card. Please notice that the SD card capacity is up to 16GB. Please check all the specifications of this unit here http://www.extech.com/products/resources/SDL100_UM-en.pdf
