TMAH Conductivity Meter HE-960TM

TMAH Conductivity Meter. Perfect for Controlling TMAH Developer Concentrations

The HE-960TM offers high precision measurement of the conductivity of TMAH (Tetra Methyl Ammonium Hydroxide) solutions, the main component of the photoresist developer that is used in semiconductor and liquid crystal processes.
The HE-960TM is also an environmentally-friendly product that uses lead-free solder for mounting chips on the PCB. And, with its 4-electrode FES-126Ni dedicated sensor, this unit has a high chemical resistance and offers a wide range of measurement, perfect conditions for measuring TMAH.
