It is very important that suitable multi meters are used to take measurements. We are often asked what would be a suitable DVM for monitoring our electrodes in service. We recommend two types of meters which have both high and low input impedance.
- the Metrix MX56C Digital Multimeter which is a rugged unit suitable for site uses and has high and low input impedance . Details for the unit can be found by clicking here.
- the Escort-99 multimeter has an input impedance of >1Gohm on the 0-1000mV scale and 10Mohm for 5-1000V range.Details for the unit can be found by clicking here.
