For a limited time purchases of the ExtechSDL100 come with a free Extech 401014 Big Digit Indoor/Outdoor Thermometer.
The Extech SDL100 displays and stores pH readings (from 0 to 14.00 pH) and ORP readings ((±1999mV). It is supplied with a temperature probe which can be inserted into the meter and offers automatic temperature compensation. The logger stores data on an SD card which can then be transferred onto a PC. The RS-232 port enables users to stream data directly onto a computer.
The large, backlit LCD dual display is incredibly easy to read, and shows pH or mV alongside Temperature. Accurate readings are ensured with a 3 point calibration. The SDL100 stores 99 readings manually and 20M readings via the 2G SD card. A Min/Max function and Data Hold (which will freeze readings on the screen) are included as standard. The automatic shutdown feature conserves battery life.

Bought four of the SDL100 loggers. Each one had a consistent quality build. Easy to follow set up instructions, and worked exactly as I hoped.
