Whether you are surveying in the desert, monitoring in the field or testing in the laboratory, the RefineTM JR series of portable reference electrodes offer a reliable, rugged and accurate device that never lets you down. Precision engineered to work with all existing field equipment on the market today, and with a range of tips and choice of gel or solution fill.
Select JR1 cell (conical ceramic tip) when taking measurements on general soils and sands.
Select JR2 cell (flat ceramic tip) when taking measurements on hard surfaces such as tarmac and concrete. Best results obtained where surface is wetted and a temporary wetted sponge is placed and fitted over the ceramic tip of the cell.
The JR1 and JR2 electrodes should be calibrated on a regular basis to ensure accuracy and the media should be replenished when spent.
