Limited time offer! FREE digital meter with purchase of micro electrode Selection of pH, redox ORP, DO & common ion electrodes

Receive a free digital meter ($190 - $290 value*) when purchasing one of our industry-standard micro electrodes. Choose between micro pH, micro redox, micro DO or micro ion electrodes.

Our industry standard micro electrodes have been can measure samples as small as 10 microliters which is less than 1/5 the volume of a single drop of liquid. They can also measure small biological and chemical specimens down to less than 1 mm in length. The probes have tips sizes from 0.5 to 2 mm.

Purchase any of the following electrodes and receive a companion digital meter FREE:

• Micro pH electrode - FREE digital pH meter with purchase.
• Micro redox electrode - FREE compatible redox millivolt meter with purchase.
• pO2, PCO2 & O2 needle electrode - FREE compatible concentration readout meter with purchase.
• Micro ion selective electrodes - micro measurement for large selection of ions including Cl, K, Na, F, CN, NO3, SO4, O2, I, Br, S, Ag, Cu, Pb, Cd, Hg, ClO4, Ba, and CO2. Receive a FREE compatible millivolt meter with purchase.
