HIOKI - Multi-range EC Meters
Brand: Hioki
Model: HI8633 & HI8733
The HI8633 and HI8733 conductivity meters have been designed for use in areas of production and quality control. These meters utilize four-ring potentiometric probes that o&er greater versatility over typical amperometric designs. These rugged probes are made of PVC and are ideal for indoor as well as outdoor measurements. HI8733’s conductivity measurements can be automatically temperature compensated by using the HI76302W probe with the built-in temperature sensor. Temperature compensation for HI8633 is performed by manual adjustment.
